The present invention relates to a light and shadow projection system, in particular to an interactive banquet light and shadow projection system and method thereof. The present invention also relates to an interactive banquet light and shadow projection method of the system.

Many banquets require a carpet entrance ceremony, which is usually held at important social occasions. These banquets may include weddings, award ceremonies, film festivals, fashion shows, charity parties, etc. The above banquets usually create a grand atmosphere by laying carpets, which adds visual appeal to these banquets to welcome important guests. For example, at a wedding banquet, the bride usually walks on a specially designed wedding carpet, symbolizing the beginning of her new life. There may be flowers or other decorations on the carpet to add romance and ceremony.

However, existing carpet items are usually relatively simple and cannot meet the modern people's constant pursuit and changes in visual effects. In addition, existing lighting equipment cannot effectively produce special effects suitable for carpets to achieve a perfect combination with the space.

According to one embodiment of the present invention, an interactive banquet light and shadow projection system is proposed, which includes a light and shadow object database, a light and shadow image generation module and a light and shadow image projection module. The light and shadow object database stores a plurality of light and shadow objects. The light and shadow image generation module captures the image of the predetermined carpet area of the banquet venue, and selects one or more of the light and shadow objects to obtain a plurality of selected light and shadow objects, and generates a light and shadow carpet image matching the surface visual features of the image of the predetermined carpet area and the selected light and shadow objects. The light and shadow image projection module projects the light and shadow carpet image to the predetermined carpet area, so that the predetermined carpet area produces a mixed virtual and real light and shadow carpet visual effect.

The following will refer to the relevant drawings to illustrate the embodiments of the interactive banquet light and shadow projection system and method according to the present invention. For the sake of clarity and convenience of the diagram description, the components in the diagram may be exaggerated or reduced in size and proportion. In the following description and/or patent application, when it is mentioned that an element is "connected" or "coupled" to another element, it may be directly connected or coupled to the other element or there may be an intervening element; and when it is mentioned that an element is "directly connected" or "directly coupled" to another element, there is no intervening element, and other words used to describe the relationship between elements or layers should be interpreted in the same way. For ease of understanding, the same elements in the following embodiments are illustrated with the same symbols.

Please refer to Figure 1 and Figure 2, which are a block diagram and a schematic diagram of the interactive banquet light and shadow projection system of the first embodiment of the present invention. As shown in the figure, the interactive banquet light and shadow projection system 1 includes a light and shadow object database 11, a light and shadow image generation module 12 and a light and shadow image projection module 13. The interactive banquet light and shadow projection system 1 can be applied to various banquets. The "banquet" described in this manual generally refers to various occasions such as weddings, award ceremonies, film exhibitions, fashion shows, charity parties, etc., but is not limited to these.

The light and shadow object database 11 stores a plurality of light and shadow objects. These light and shadow objects can be various patterns, such as flowers, insects, animals, fruits, buildings, and geometric shapes. In one embodiment, the light and shadow object database 11 can be a storage device, such as a hard drive, various computers, cloud storage devices, etc.

The light and shadow image generation module 12 captures the image of the predetermined carpet area PS of the banquet venue, and selects one or more of the light and shadow objects 111 to obtain a plurality of selected light and shadow objects 121, and generates a light and shadow carpet image 122 matching the surface visual features of the image of the predetermined carpet area PS of the banquet venue and the selected light and shadow objects 121. The predetermined carpet area PS may be a floor or a floor with a carpet. In one embodiment, the light and shadow image generation module 12 may be a personal computer, a laptop, a workstation, a server or other similar devices.

The light and shadow image projection module 13 projects the light and shadow carpet image 122 onto the predetermined carpet area PS, so that the predetermined carpet area PS produces a mixed virtual and real visual effect. In one embodiment, the light and shadow image projection module 13 can be a projector or other similar components.

As can be seen from the above, the interactive banquet light and shadow projection system 1 can generate a light and shadow carpet image 122 that matches the predetermined carpet area PS according to the selected light and shadow objects 121 through the light projection technology to generate a dazzling and vivid light and shadow carpet image 122. Among them, the light and shadow image generation module 12 can first capture and store the image of the predetermined carpet area PS of the banquet venue, which has a surface visual feature; this surface visual feature can include the surface texture of the predetermined carpet area PS. Then, the light and shadow image generation module 12 can perform texture special effect processing to superimpose visual special effects such as color block elements and particles on the surface texture of the predetermined carpet area PS. Next, the light and shadow image generation module 12 can perform shadow special effect processing to add shadow special effect to the surface texture of the predetermined carpet area PS so as to present a three-dimensional visual effect. Finally, the light and shadow image generation module 12 can perform color special effect processing to fill the surface texture of the predetermined carpet area PS with appropriate colors so as to achieve vivid color changes. Through the above-mentioned various special effect processing, the light and shadow image generation module 12 can generate a light and shadow carpet image 122 that matches and blends with the predetermined carpet area PS according to the selected light and shadow objects 121, which can have virtual and real mixed projection effects such as color block elements, particle dynamics, shadow changes, three-dimensional visual effects, and vivid color changes. In this way, the light and shadow carpet image 122 can blend with the texture of the predetermined carpet area PS itself to produce a virtual and real mixed projection effect. Therefore, the interactive banquet light and shadow projection system 1 can generate a light and shadow carpet image 122 with rich visual effects, so as to achieve a perfect combination of the light and shadow carpet image 122 and the space.

Of course, this embodiment is only used for illustration and not to limit the scope of the invention. Equivalent modifications or changes made to the interactive banquet light and shadow projection system 1 of this embodiment should still be included in the patent scope of the invention.

Please refer to Figure 3, which is a block diagram of the interactive banquet light and shadow projection system of the second embodiment of the present invention, and please refer to Figure 2 at the same time. As shown in the figure, the interactive banquet light and shadow projection system 1 includes a light and shadow object database 11, a light and shadow image generation module 12 and a light and shadow image projection module 13.

The above-mentioned components are similar to the aforementioned embodiments, so they will not be described in detail here. Unlike the aforementioned embodiments, the interactive banquet light and shadow projection system 1 further includes a motion detection module 14. The motion detection module 14 detects the gait and/or speed of the target object BT (as shown in FIG. 2, the target object BT of this embodiment is a bride, but is not limited to this; in another embodiment, the target object BT may also be a groom or other important person) to generate a motion detection result 141. Then, the light and shadow image generation module 12 adjusts a plurality of light and shadow parameters of the light and shadow carpet image 122 according to the motion detection result 141. For example, these light and shadow parameters may include but are not limited to one or more of the color, brightness, size, pattern and movement speed of the light and shadow carpet image 122. In one embodiment, the motion detection module 14 may be an infrared sensor, a 3D scanning device, an image recognition system capable of performing motion detection, etc.

For example, when the gait of the target object BT is slow, the light and shadow image generation module 12 adjusts the color of the light and shadow carpet image 122 according to the motion detection result 141, so that it changes from light to dark (or from dark to light) at a slower speed. On the contrary, when the gait of the target object BT is fast, the light and shadow image generation module 12 adjusts the color of the light and shadow carpet image 122 according to the motion detection result 141, so that it changes from light to dark (or from dark to light) at a faster speed. Similarly, the light and shadow image generation module 12 can also adjust the brightness of the light and shadow carpet image 122 according to the gait of the target object BT, so that it changes from light to dark (or from dark to light) at a speed corresponding to the gait of the target object BT. The light and shadow image generation module 12 can also adjust the size or pattern of the light and shadow carpet image 122 according to the gait of the target object BT, so that it changes at a speed corresponding to the gait of the target object BT. In another embodiment, when the gait of the target object BT is fast, the light and shadow image generation module 12 adjusts the moving speed of the selected light and shadow object 121 of the light and shadow carpet image 122 according to the motion detection result 141, so that it moves with the target object BT, thereby generating a vivid and interactive visual effect.

As can be seen from the above, in this embodiment, the interactive banquet light and shadow projection system 1 has a motion detection module 14. The motion detection module 14 can detect the gait and/or speed of the target object BT to generate a motion detection result 141. The light and shadow image generation module 12 adjusts a plurality of light and shadow parameters of the light and shadow carpet image 122 according to the motion detection result 141, such as one or more of color, brightness, size, pattern and moving speed. Therefore, the interactive banquet light and shadow projection system 1 can generate a light and shadow carpet image 122 that can interact with the target object BT, so that the light and shadow carpet image 122 can achieve an interactive visual effect to produce an eye-catching visual special effect.

Of course, this embodiment is only used for illustration and not to limit the scope of the invention. Equivalent modifications or changes made to the interactive banquet light and shadow projection system 1 of this embodiment should still be included in the patent scope of the invention.

Please refer to Figures 4, 5 and 6. Figure 4 is a block diagram of the interactive banquet light and shadow projection system of the third embodiment of the present invention. Figures 5 and 6 are respectively the first schematic diagram and the second schematic diagram of the interactive banquet light and shadow projection system of the third embodiment of the present invention. As shown in Figure 4, the interactive banquet light and shadow projection system 1 includes a light and shadow object database 11, a light and shadow image generation module 12, a light and shadow image projection module 13 and a motion detection module 14.

The above components are similar to the above embodiments, so they will not be described in detail here. Different from the above embodiments, the interactive banquet light and shadow projection system 1 further includes a moving track tracking module 15. The moving track tracking module 15 can detect the target object BT to calculate the offset 151 of the detected target object BT relative to the predetermined carpet area PS, and control the light and shadow image projection module 13 according to the above offset 151 to adjust the light and shadow carpet image 122. In one embodiment, the moving track tracking module 15 can be a combination of a camera and a computing device. The computing device can be, but is not limited to, a central processing unit, a special application integrated circuit chip, etc.

In this embodiment, the moving track tracking module 15 detects a first feature point P1 of the left foot of the target object BT and a second feature point P2 of the right foot of the target object BT. The first feature point P1 and the second feature point P2 are points that can represent the movement directions of the left foot and the right foot of the target object BT, respectively; for example, the first feature point P1 and the second feature point P2 can be the toe of the left foot and the toe of the right foot, respectively. Then, the moving track tracking module 15 calculates the reference point P0 between the first feature point P1 and the second feature point P2 when the time interval when the first feature point P1 and the second feature point P2 are at a preset distance is within the preset time interval. The aforementioned default distance can be the average distance of a person's stride when walking (e.g., 10 cm to 25 cm), which can be appropriately adjusted according to the target BT's gender and age, etc. Since a person's feet touch the ground at the same time for a short period of time when walking, this time interval can be the aforementioned default time interval (e.g., 0.1 second to 0.5 second), which can also be appropriately adjusted according to the target BT's gender and age, etc. When the above conditions are met (the first feature point P1 and the second feature point P2 are at a preset distance, and the time interval between the first feature point P1 and the second feature point P2 is within the preset time interval), the moving track tracking module 15 can calculate the reference point P0 between the first feature point P1 and the second feature point P2; the reference point P0 can be the midpoint between the first feature point P1 and the second feature point P2. Then, the moving track tracking module 15 calculates the offset 151 between the reference point P0 and the preset track line L1 of the predetermined carpet area PS; the preset track line L1 can be the center line of the predetermined carpet area PS (the center line can cut the predetermined carpet area PS into two parts of equal area), but is not limited thereto. In another embodiment, the preset track line L1 may also be a straight line parallel to the center line of the predetermined carpet area PS. Finally, the moving track tracking module 15 controls the light and shadow image projection module 13 according to the offset to appropriately move the light and shadow carpet image 122 so that the light and shadow carpet image 122 can move with the target object BT. In another embodiment, the first feature point P1 and the second feature point P2 may be the heel of the left foot and the heel of the right foot, respectively. In another embodiment, the first feature point P1 and the second feature point P2 may also be adjusted according to actual needs.

As shown in FIG. 5 , the moving track tracking module 15 can calculate the offset 151 between the reference point P0 and the preset track line L1 of the predetermined carpet area PS as 0 through the above-mentioned mechanism. At this time, the moving track tracking module 15 controls the light and shadow image projection module 13 to keep the light and shadow carpet image 122 from moving left or right.

As shown in FIG. 6 , the moving track tracking module 15 can calculate the offset 151 between the reference point P0 and the preset track line L1 of the predetermined carpet area PS as the distance D1 through the above-mentioned mechanism. At this time, the moving track tracking module 15 controls the light and shadow image projection module 13 to keep the light and shadow carpet image 122 moving to the left. In this way, the light and shadow carpet image 122 can move with the target object BT.

As can be seen from the above, the interactive banquet light and shadow projection system 1 has a moving track tracking module 15. The moving track tracking module 15 detects the offset 151 between the moving track of the target object BT and the preset track line of the predetermined carpet area PS, and adjusts the light and shadow carpet image 122 according to the offset. Therefore, the light and shadow carpet image 122 can change with the moving track of the target object BT to further enhance the interactive visual effect of the light and shadow carpet image 122.

Of course, this embodiment is only used for illustration and not to limit the scope of the present invention. Equivalent modifications or changes made to the interactive banquet light and shadow projection system 1 of this embodiment should still be included in the patent scope of the present invention.

It is worth mentioning that the carpets in existing banquet venues are usually relatively simple and cannot provide any special effects. Existing lighting equipment cannot effectively produce special effects suitable for carpets to achieve a perfect combination with the space. On the contrary, according to an embodiment of the present invention, an interactive banquet light and shadow projection system includes a light and shadow object database, a light and shadow image generation module, and a light and shadow image projection module. The light and shadow object database stores a plurality of light and shadow objects. The light and shadow image generation module captures the image of the predetermined carpet area of the banquet venue, and selects one or more of the light and shadow objects to obtain a plurality of selected light and shadow objects, and generates a light and shadow carpet image that matches the surface visual features of the image of the predetermined carpet area of the banquet venue and the selected light and shadow objects. The light and shadow image projection module projects the light and shadow carpet image onto the predetermined carpet area, so that the predetermined carpet area produces a mixed virtual and real light and shadow carpet visual effect. Therefore, the interactive banquet light and shadow projection system can produce a dazzling and vivid light and shadow carpet image to replace the existing carpet and combine it with the surface visual characteristics of the predetermined carpet area. Therefore, the interactive banquet light and shadow projection system can produce a light and shadow carpet image with rich visual effects to achieve a perfect combination of light and shadow carpet image and space.

Furthermore, according to an embodiment of the present invention, the interactive banquet light and shadow projection system has a motion detection module. The motion detection module can detect the gait and/or speed of the target object to generate a motion detection result. The light and shadow image generation module adjusts a plurality of light and shadow parameters of the light and shadow carpet image according to the motion detection result, such as one or more of color, brightness, size, pattern and moving speed. Therefore, the interactive banquet light and shadow projection system can generate a light and shadow carpet image with an interactive visual effect, so that the light and shadow carpet image can achieve a more eye-catching visual effect.

In addition, according to the embodiment of the present invention, the interactive banquet light and shadow projection system has a moving track tracking module. The moving track tracking module detects the offset between the moving track of the target object and the preset track line of the predetermined carpet area, and adjusts the light and shadow carpet image according to the offset. Therefore, the light and shadow carpet image can change with the moving track of the target object to further enhance the interactive visual effect of the light and shadow carpet image. From the above, it can be seen that the interactive banquet light and shadow projection system according to the embodiment of the present invention can indeed achieve excellent technical effects.

Please refer to Figure 7, which is a block diagram of the interactive banquet light and shadow projection system of the fourth embodiment of the present invention, and please refer to Figure 2 at the same time. As shown in the figure, the interactive banquet light and shadow projection system 1 includes a light and shadow object database 11, a light and shadow image generation module 12, a light and shadow image projection module 13, a motion detection module 14 and a movement trajectory tracking module 15.

The above-mentioned components are similar to the aforementioned embodiments, so they will not be described in detail here. Unlike the aforementioned embodiments, the interactive banquet light and shadow projection system 1 further includes an artificial intelligence module 16. The artificial intelligence module 16 can analyze the personal information 161 of the target object BT, and the light and shadow image generation module 12 selects one or more of the light and shadow objects 111 according to the personal information to obtain the selected light and shadow objects 121. The personal information 161 of the target object BT may include but is not limited to gender, race, age, etc. Therefore, the artificial intelligence module 16 can infer the preferences of the target object BT based on the personal information 161 of the target object BT, so that the light and shadow image generation module 12 can find the selected light and shadow objects 121 that are more likely to meet the preferences of the target object BT from the light and shadow objects 111. Through the above mechanism, the light and shadow image generation module 12 can generate a light and shadow carpet image 122 that is more in line with the preferences of the target object BT.

Of course, this embodiment is only used for illustration and not to limit the scope of the invention. Equivalent modifications or changes made to the interactive banquet light and shadow projection system 1 of this embodiment should still be included in the patent scope of the invention.

Please refer to Figure 8, which is a block diagram of the interactive banquet light and shadow projection system of the fifth embodiment of the present invention, and please refer to Figure 2 at the same time. As shown in the figure, the interactive banquet light and shadow projection system 1 includes a light and shadow object database 11, a light and shadow image generation module 12, a light and shadow image projection module 13, a motion detection module 14, a movement trajectory tracking module 15 and an artificial intelligence module 16.

The above-mentioned components are similar to the aforementioned embodiments, so they will not be described in detail here. Different from the aforementioned embodiments, the interactive banquet light and shadow projection system 1 further includes a cloud server 17. In addition, the user can interact with the interactive banquet light and shadow projection system 1 through the electronic device ED. The above-mentioned electronic device ED can be a smart phone, a smart watch, a tablet computer, a laptop computer, a personal computer, etc. By installing a corresponding application on the electronic device ED, the user can send an operation instruction Ls to the light and shadow image generation module 12 through the electronic device ED to select one or more of the light and shadow objects 111 in the light and shadow object database 11, thereby generating the selected light and shadow objects 121. In addition, the user can also upload the light and shadow objects 111 that meet the user's preferences to the light and shadow image generation module 12 as the selected light and shadow objects 121. On the other hand, the user can also send an operation instruction Ls to the light and shadow image generation module 12 by operating the application of the electronic device ED to change the color and size of the selected light and shadow objects 121, or perform some personalized adjustments.

At the same time, the light and shadow image generation module 12 also transmits the user's operation command Ls to the cloud server 17. Then, the cloud server 17 can store each user's operation command Ls, gender, race, age and other personal information, and perform big data analysis. In this way, the cloud server 17 can provide various special recommendation solutions after a period of time and transmit them to the light and shadow image generation module 12. For example, the cloud server 17 can provide a light and shadow object combination or a light and shadow carpet image 122 that meets the user's gender, race, and age as a recommendation solution based on the user's personal information. For example, the light and shadow image generation module 12 can also provide the light and shadow object combination or the light and shadow carpet image 122 that is most popular with the public as a recommendation solution. In this way, when the user interacts with the interactive banquet light and shadow projection system 1 through the electronic device ED, he can directly choose from the above-mentioned recommended solutions.

Of course, this embodiment is only used for illustration and not to limit the scope of the invention. Equivalent modifications or changes made to the interactive banquet light and shadow projection system 1 of this embodiment should still be included in the patent scope of the invention.

The light and shadow object database stores a plurality of light and shadow objects. The light and shadow image generation module captures an image of a predetermined carpet area of a banquet venue, and selects one or more of the light and shadow objects to obtain a plurality of selected light and shadow objects, and generates a light and shadow carpet image matching the surface visual features of the image of the predetermined carpet area of the banquet venue and the selected light and shadow objects. The light and shadow image projection module projects the light and shadow carpet image to the predetermined carpet area, so that the predetermined carpet area produces a mixed virtual and real light and shadow carpet visual effect. Therefore, the interactive banquet light and shadow projection system can produce dazzling and vivid light and shadow carpet images to replace the existing carpet and combine with the surface visual characteristics of the predetermined carpet area. Therefore, the interactive banquet light and shadow projection system can produce light and shadow carpet images with rich visual effects to achieve a perfect combination of light and shadow carpet images and space.

Furthermore, according to an embodiment of the present invention, the interactive banquet light and shadow projection system has a motion detection module. The motion detection module can detect the gait and/or speed of the target object to generate a motion detection result. The light and shadow image generation module adjusts a plurality of light and shadow parameters of the light and shadow carpet image according to the motion detection result, such as one or more of color, brightness, size, pattern and moving speed. Therefore, the interactive banquet light and shadow projection system can generate a light and shadow carpet image with an interactive visual effect, so that the light and shadow carpet image can achieve a more eye-catching visual effect.

In addition, according to an embodiment of the present invention, the interactive banquet light and shadow projection system has a moving track tracking module. The moving track tracking module detects the offset between the moving track of the target object and the preset track line of the predetermined carpet area, and adjusts the light and shadow carpet image according to the offset. Therefore, the light and shadow carpet image can change with the moving track of the target object to further enhance the interactive visual effect of the light and shadow carpet image.

In addition, according to an embodiment of the present invention, the interactive banquet light and shadow projection system has an artificial intelligence module. The artificial intelligence module can analyze the personal information of the target object. The light and shadow image generation module selects one or more of the light and shadow objects according to the personal information to obtain the selected light and shadow objects. Therefore, through the above mechanism, the light and shadow image generation module can generate a light and shadow carpet image that is more in line with the preferences of the target object.

Furthermore, according to the embodiments of the present invention, the interactive banquet light and shadow projection system can be applied not only to banquet venues, but also to other banquets or ceremonies to provide a light and shadow carpet image with interactive visual effects. Therefore, the application of the interactive banquet light and shadow projection system can be more extensive and more flexible in use.

It can be seen that this invention has indeed achieved the desired improved effect by breaking through the previous technology, and it is not easy for people familiar with the technology to think of. Its progress and practicality obviously meet the patent application requirements. Therefore, I have filed a patent application in accordance with the law and sincerely request your approval of this invention patent application to encourage creativity.
