Therefore, for those skilled in the art, without departing from the spirit and principles of the present invention, various changes and modifications to the present invention should be obvious and can be easily achieved.

According to an embodiment of the present invention, referring to FIG. 1 , a system 10 capable of generating projection light includes a sensing module 100 , a control module 200 , and a display module 300 . Wherein, the sensing module 100 is configured to sense the light information F of the ambient light AL. Specifically, the sensing module 100 can be installed in any specific environment, and sense the ambient light AL of the specific environment, so as to obtain the light information F of the ambient light AL. For example, the light information F of the ambient light AL may include direct light angle, direct light intensity, direct light color temperature, diffuse light intensity, diffuse light color temperature, or a combination thereof. In addition, ambient light AL refers to the comprehensive performance of light in an actual specific environment, and is not limited to sunlight, other natural light or artificial light. As mentioned above, according to this embodiment, the sensing module 100 of the system 10 can transmit the light information F to the control module 200 of the system 10 after obtaining it. Next, the control module 200 receives the light information F of the ambient light AL sensed by the sensing module 100 , and generates a projection light signal N according to the light information F. Then, the control module 200 transmits the projection light signal N to the display module 300 .

According to some embodiments, the control module 200 can include an electronic control circuit with a single-chip microcontroller (Microcontroller Unit, MCU) such as Arduino, ARM, Raspberry Pi, etc. to receive light information F, and can use commercially available Windows/Android/ SoC and other systems write logic control programs to analyze and judge light information F and generate projected light signals N. However, as long as the above actions and functions can be realized, the embodiments of the present invention are not limited thereto.

As above, the display module 300 can generate a projection light PL, and adjust the optical properties of the projection light PL according to the projection light signal N. That is, the display module 300 can generate the projection light PL corresponding to the light information F. For example, the sensing module 100 can obtain light information F including direct light angle, direct light intensity, direct light color temperature, diffuse light intensity, and diffuse light color temperature, which reflect the optical properties of the ambient light AL. Then, the control module 200 generates the projection light signal N after receiving the light information F, and makes the display module 300 generate corresponding projection light PL of direct light and diffuse light. Wherein, the direct light itself and/or the irradiated place of the projection light PL generated by the display module 300 may have a light output angle corresponding to (for example, the same as) the direct light angle, direct light intensity, and direct light color temperature in the light information F , the output light intensity, and the light output color temperature, and the diffuse light itself and/or the irradiated place of the projected light PL generated by the display module 300 may have the diffuse light intensity and the diffuse light color temperature corresponding to (for example, the same as) the light information F The output illuminance and color temperature of the output light. In this way, the display module 300 installed in the predetermined space can be projected by simulating the ambient light AL of the above-mentioned specific environment, so that the predetermined space can have light projection and/or light and shadow changes similar or identical to the ambient light AL of the above-mentioned specific environment. .

In addition, the diffused light can be, for example but not limited to, simulating weak sunlight or indoor lighting that brightens the overall environment, and according to the actual specific environment, the light output capability of the display module 300 and the distance from the display module 300 can be, for example, but Not limited to having illuminance from 0 lux to 1200 lux. For example, the simulated indoor diffuse light of a convenience store may be about 800 lux, and the simulated indoor diffuse light of a general household may be about 200 lux, but the present invention is not limited to these situations. Based on the above, according to some embodiments, direct light is light with higher illuminance relative to diffuse light, and may have an irradiating range or limited irradiating angle recognizable by human eyes; while diffuse light is light with lower illuminance than direct light. light, and may be evenly or widely irradiated, without an irradiated area discernible by the human eye or with a relatively wide irradiated angle.

Next, please refer to FIG. 2A to FIG. 2C , according to an embodiment of the present invention, the sensing module 100 may be configured to include a sensor array 110 , for example. Wherein, the sensor array 110 may have multiple sets of sensors 105, and each set of the multiple sets of sensors 105 is configured to sense the optical properties of the received ambient light AL independently. For example, each set of sensors 105 may have a color temperature sensor and an illuminance sensor, or may have a color temperature and illuminance integrated sensor capable of simultaneously sensing color temperature and illuminance. Alternatively, it can be a color temperature sensor, and the raw information sensed by it for sensing the color temperature can be used to convert and calculate illuminance and the like. As mentioned above, each group of sensors 105 can actually have a single or multiple sensing elements for detecting different optical properties, and a group of sensors 105 is used as the basic unit for detecting optical properties in the sensor array 110 . In addition, when each set of sensors 105 has a plurality of sensing elements for detecting different optical properties, the sensing elements can be integrated or separated. As above, under the condition that each group of sensors 105 can be used as the basic unit for detecting optical properties in the sensor array 110, the specific configuration and composition of each group of sensors 105 according to various embodiments of the present invention are not limited to Examples described above.

Based on the above, based on the optical properties of the ambient light AL received and sensed by the plurality of sensors 105 located at different positions and different angles, etc., the possible optical properties of the ambient light AL in the overall specific environment can be estimated. Optical Information F. For example, the direct light angle of the ambient light AL is estimated by the positions (such as coordinates) of several sets of sensors 105 receiving the direct light of the ambient light AL, and the optical illuminance and optical intensity sensed by the several sensors 105 The color temperature is used to calculate the direct light illuminance and direct light color temperature of the ambient light AL. In addition, the diffuse light intensity and diffuse light color temperature of the ambient light AL are estimated based on the average of the optical illuminance and optical color temperature sensed by all the sensors 105 of the group receiving the diffuse light of the ambient light AL. However, the above are examples only, and the present invention is not limited thereto.

Specifically, as shown in FIGS. 2A to 2C , the sensing module 100 may include a bowl-shaped container 120 made of opaque material, having an inner surface 121 and defining a container opening 125 . Wherein, the plurality of sensors 105 can be arranged annularly on the inner surface 121 of the bowl-shaped container 120. In addition, the sensing module 100 is further made of an opaque material and completely corresponds to the container opening 125. The baffle structure 130 is provided.

In addition, according to some embodiments, the bowl-shaped container 120 may be formed as a semi-circular body or a semi-elliptical body. For example, referring to FIG. 3 together with FIG. 2A to FIG. 2C , the bowl-shaped container 120 can be formed as a semi-elliptical body formed by rotating the lower half of the ellipse 360 degrees around the minor axis of the ellipse, and the corresponding container opening 125 is circular. . However, the above is only an illustrative example of implementation, and the present invention is not limited thereto.

For example, the opening 135 formed corresponding to the center O of the container opening 125 may be formed between the two focal points f1, f2 of the semi-elliptical shape of the section. Further, according to some embodiments, the ratio of the area of the opening 135 to the area of the container opening 125 may be between 2% and 25%. For example, the ratio of the openings 135 can be set based on the condition that the ambient light AL enters the bowl-shaped container 120 through the openings 135 and the illuminated area covers at least three sets of sensors 105 , but the invention is not limited thereto.

In addition, continue to refer to FIG. 3 , the ratio of the minor axis length b of the bowl-shaped container 120 to the major axis length a of the semi-elliptical cross-section substantially perpendicular to the installation surface of the bowl-shaped container 120 can be between 0.67 and 1. . As mentioned above, under the above configuration, the ambient light AL incident on the inner surface 121 of the bowl-shaped container 120 through the opening 135 can have a more average covering quantity or covering density of the sensors.

For example, as shown in FIG. 4 , the plurality of sensors 105 may be disposed on the inner surface 121 of the bowl-shaped container 120 in a ring shape in a configuration close to that of a pentagonal hexahedron. Alternatively, although not shown in the drawings, the plurality of sensors 105 can also be arranged in the form of a regular icosahedron and be annularly disposed on the inner surface 121 of the bowl-shaped container 120 . Above all, the above are only examples, and in the case that the sensor array 110 can be configured to determine the angle or position of the sensed ambient light AL, the complex array of sensors 105 can be implemented in any form or array. configuration, and the present invention is not limited thereto.

Further, referring to FIG. 5A , according to the sensing module 100 ′ of other embodiments of the present invention, the above-mentioned bowl-shaped container 120 may also be an octagon, or any shape not shown in the drawings of the present invention, and multiple sensory The detector 105 may be annularly disposed on the inner surface 121 of the bowl-shaped container 120 . In this way, the ambient light AL incident at different angles through the opening 135 can be sensed based on the sensors 105 at different positions, and the sensor array 110 can be configured to determine the angle or angle of the sensed ambient light AL. Location. As mentioned above, the bowl-shaped container 120 of the present invention is not limited to the shape examples specifically shown in the drawings.

For example , according to the present embodiment, the baffle structure 130' may cover the entire container opening 125 and extend beyond the container opening 125, and have a plurality of brackets 131 extending downward from the protruding baffle structure 130' to establish a sense The installation surface of the measurement module 100" assists in supporting and stabilizing the sensing module 100". On top of that, under the circumstances that the ambient light AL can be incident through the opening 135 and the incident angle is different, the bowl-shaped according to various embodiments of the present invention The forms of the container 120 and the baffle structure 130' are not limited to the examples shown here.

Step S200 is a direct light group determination step, which determines the direct light group G0 receiving the direct light 510 of the ambient light AL from one or more height illuminance groups G', and if it is determined that there is no direct light group G0 then Go directly to step S400, and continue if there is;

Step S300 is a direct light information extraction step, which extracts the average sensing result of the optical properties of the ambient light AL sensed by the direct light group G0 as information relative to the direct light 510 in the light information F, and based on the direct light The position set by the group G0 is used to capture the angle of the direct light in the light information F. If it is judged that there is no direct light group G0, the information corresponding to the direct light 510 in the light information F is not retrieved;

Step S400 is the stray light information extraction step, which removes the direct light group G0 and extreme outliers (for example, the result of the sensor 105 that may be faulty, too dark, too bright, or directly pointed by laser light, etc. ), the average sensing result of the optical properties of the ambient light AL sensed by the sensor array 110 is taken as the information corresponding to the diffuse light 520 in the light information F.

To sum up, the sensing step S10 can be implemented through the above steps S0 , S100 , S200 , S300 and S400 , so that the sensing module 100 senses the light information F of the ambient light AL. For example, direct light angle, direct light illuminance, direct light color temperature, diffuse light illuminance, diffuse light color temperature, or a combination thereof. However, the above is just an example, and the details of the sensing step S10 in other embodiments of the present invention are not limited thereto.

According to yet another embodiment of the present invention, referring to FIG. 13 , step S100 can be performed as described above in FIG. 11 and FIG. 12 , and the specific implementation details of step S200 in the step of judging the direct light group include the following steps:

Step S210 is a quantity judging step, which judges whether the number of the high-illuminance group G' is single, and if it is single, directly judges that the high-illuminance group G' is the direct light group G0, and ends step S200 and enters step S300 , if it is plural rather than single, continue:

Step S220 is a dispersion judgment step, which judges whether a plurality of high illuminance groups G' are adjacent, and if adjacent, then judges that a highest illuminance group with the highest average illuminance among the plurality of high illuminance groups G' is Direct light group G0 (step S221), and end step S200 and enter step S300; if it is not adjacent, then further determine the average of the highest illuminance group with the highest average illuminance among the plurality of height illuminance groups G' Whether the illuminance is greater than twice the average illuminance of the primary high illuminance group having the second highest average illuminance among the plurality of high illuminance groups G' (step S222 ). Continuing from the above, if the average illuminance of the ambient light AL sensed by the highest illuminance group is more than twice the average illuminance of the ambient light AL sensed by the second highest illuminance group, then it is determined that the highest illuminance group is the direct light group G0 ( Step S223), and end step S200 and enter step S300; and if the average illuminance of the ambient light AL sensed by the highest illuminance group does not reach more than twice the average illuminance of the ambient light AL sensed by the second highest illuminance group, then judge There is no direct light group G0, and step S200 is ended and directly enters step S400.

The process of determining the direct light group described above is only an example, and other embodiments of the present invention are not limited thereto. Continuing from the above, the direct light group of the ambient light AL sensed by the sensing module 100 can be judged in any way, so as to perform other actions to obtain, for example, the direct light angle, the direct light intensity, the direct light color temperature, the diffuse light intensity, Diffuse light color temperature or light information F of its combination, and implement corresponding projection light PL projection. In addition, according to some embodiments, the generated projection light PL may include direct light 510 and diffuse light 520 at the same time, or may only include direct light 510 or diffuse light 520 or further include other types of projection light, and the present invention is not limited thereto The specified form.

For example, a context that corresponds to a particular environment where a locomotive looks ahead and the train moves forward along the rails. Continuing from the above, with the change of time and the change of the corresponding viewing angle and position, as shown in the right part of Figure 15, the display module 300 or 300' can simulate the change of the scene and the change of light and shadow corresponding to the change of time and position and angle. For example, the image information M of the scene that can be seen at the position after driving forward along the track can be displayed, and the light and shadow changes caused by the surrounding objects corresponding to the scene change (such as blocking light or passing light) are correspondingly Projecting direct light 510 or diffuse light 520 with changing angles or optical properties makes the overall scene and the effect and atmosphere created by the projected light and shadow closer to the situation of the specific moving environment where ambient light AL is sensed and image information M is captured.

In addition, it is also possible to establish and set multiple sets of matching scenes and light and shadow changes for people to choose by themselves.
