Description

Mounting bracket for tracking camera equipment and panoramic camera inside

This work is about tracking camera equipment; in particular, about searching within tracking camera equipment, and devices used for searching such as panoramic cameras.

Please refer to FIG1 for a schematic diagram of a tracking camera device for use. Due to factors of the venue, such as a lecture hall, a lecture hall, or a performance hall, in order to cover the whole scene as much as possible, the tracking camera device 1 is usually set at a position slightly above the back of the entire venue. In addition to making the viewing angle cover a wider range, it can also avoid photographing the audience and listeners. For example, the tracking camera device 1 in this figure is horizontally set on a high platform 4, and a tracking camera 3 is also set on the tracking camera device 1 through a trolley 30. It is a PTZ (Pan, Tilt, Zoom) camera, and the Z axis of the tracking camera 3 is parallel to the normal vector N of the plane of the platform 4. However, the tracked object will actually approach or move away from the tracking camera device 1, and the search device 2 thereon usually has a fixed viewing angle, that is, the angle between the upper boundary 2B1 and the lower boundary 2B2 will not change, and the visual axis 2A is also fixed in direction. Therefore, if the tracked person P is too close to the tracking camera device 1, that is, when it is at the second position P2 instead of the first position P1, the tracked person P is only partially tracked, which is likely to cause the search device 2 to unlock, and then the tracking camera 3 can no longer track the tracked person P.

Please refer to FIG. 2, which is a schematic diagram of using the tracking camera device to shoot at an angle. In order to prevent the search device 2 from being unlocked when the person being tracked P is at the second position P2, the method in this figure is to tilt the tracking camera device 1 on the platform 4 so that the visual axis 2A of the search device 2 is downward, and the upper boundary 2B1 and the lower boundary 2B2 move downward accordingly, so that the search device 2 can more completely cover the second position P2, so that the search device 2 can capture a more complete image of the person being tracked P. However, when the tracking camera device 1 is tilted at an angle α, the Z axis of the tracking camera 3 and the normal vector N of the plane of the platform 4 also form an angle α, thereby making the rotation and pitch control of the tracking camera 3 more complicated. The reason for the complexity is that the default reference for the rotation and pitch control of the tracking camera 3 is that its own rotation plane is parallel to the ground. In other words, the Z axis of the tracking camera 3 is parallel to the normal vector of the ground, that is, the plane where the tracked object is located is preset to be parallel to the plane where the tracking camera 3 is located. Therefore, when the search device 2 determines the plane coordinates of the tracked person P, the tracking camera device 1 can simply convert and control the rotation and pitch of the tracking camera 3 to capture a close-up of the tracked object. If the plane where the tracking camera 3 is set is not parallel to the plane where the tracked object is located, the tracking camera 3 will not be able to correctly align with the tracked object. To this end, the applicant has put in great effort and proposed the "tracking camera device and the mounting bracket of the panoramic camera therein" of this invention, so that the pitch of the search device 2 (i.e., the panoramic camera) used to search for the tracked person P can be independent of the posture of the tracking camera device, so as to avoid the need for additional calculation or compensation for the rotation and pitch control of the tracking camera 3.

In order to achieve the purpose of "the pitch of the search device (usually a panoramic camera) can not affect the posture of the tracking camera equipment, so that the rotation and pitch control of the tracking camera remains simple", this creation "tracking camera equipment and the mounting frame of the panoramic camera therein" mainly provides a pitch mechanism for the mounting frame of the search device (usually a panoramic camera) in the tracking camera equipment separately, so that the adjustment of the pitch angle of the search device does not need to change the overall posture of the tracking camera equipment, that is, the tracking camera equipment can maintain the original installation posture, that is, the installation plane of the tracking camera equipment is parallel to the plane where the object being tracked is located, so as to achieve the effect of "not affecting the rotation and pitch control of the tracking camera". The mounting frame has two parts, a first part and a second part, one of which is fixed to the casing, housing, or fixed frame of the tracking camera device, and the other is used to install a panoramic camera. The first part and the second part are connected together in a way that the angle can be changed with each other, usually by hinge or twist. There is also a fixing device between the first part and the second part, so that the relative angle between the two can be fixed and no longer rotated after it is determined. Therefore, through this creation "tracking camera device and the mounting frame of the panoramic camera therein", the tracking camera device can change the pitch angle of the search device when it is on a higher shelf or inverted on the ceiling, without changing the posture of the tracking camera device itself.

Therefore, in order to achieve the above-mentioned purpose, this invention provides an automatic tracking photography device, including: a body, in which a panoramic photography device is provided, wherein the panoramic photography device includes: a first component, fixed in the body, and having a plurality of first positioning parts; and a second component, pivotally connected to the first component via a rotating shaft, and having a second positioning part, which is used to engage with one of the plurality of first positioning parts, and a panoramic camera is provided on the second component, wherein the second positioning part changes a pitch angle of the panoramic camera by engaging with different first positioning parts; and a panorama frame, which can be movably provided on the body, and a PTZ camera is provided on the panorama frame.

In order to achieve the above-mentioned purpose, the present invention further provides a photographic device, including: a search device having a visual axis for searching a target, and including: a first component; a second component pivotally mounted on the first component and capable of rotating in a pitching manner to change a pitch angle of the visual axis; and an angle fixing mechanism for fixing the pitch angle of the visual axis, and including: a plurality of first positioning parts, disposed on one of the first component and the second component; and a second positioning part, disposed on the other of the first component and the second component, and abutting against one of the plurality of first positioning parts, thereby fixing the pitch angle; and a tracking camera having a cradle, mounted on the search device via the cradle, and used to track the target.

In order to achieve the above-mentioned purpose, the invention further provides a mounting bracket for a panoramic camera, wherein the panoramic camera has a body, a lens, and a photosensitive element, including: a first component, which is arranged inside the body, connected to the body, and has a plurality of first positioning parts; and a second component, which is arranged inside the body, pivotably connected to the first component, has a second positioning part, and is used to carry the lens and the photosensitive element, wherein the second positioning part and the first positioning part have a plurality of positioning positions for selecting a pitch angle of the lens.

Please refer to Figure 3, which is a schematic diagram of the tilt angle of the whole camera in the tracking camera device of this invention. It reveals that the tracking camera device 1 is set at the upper back of the entire venue, in order to cover a wider range of viewing angles and avoid photographing the audience and listeners. For example, the tracking camera device 1 in this figure is horizontally set on a high platform 4, and the Z axis of the tracking camera 3 is parallel to the normal vector N of the plane of the platform 4. In order to allow the tracked person P to be seen by the search device 2 (usually a panoramic camera) thereon when the person is close to the tracking camera 1, that is, at the second position P2, the direction of the visual axis 2A of the search device 2 is adjusted downward, that is, the search device 2 is rotated in the direction of the second position P2. Although the angle between the upper boundary 2B1 and the lower boundary 2B2 does not change, both of them move downward so that the lower boundary 2B2 can cover a position closer to the tracking camera 1, that is, the second position P2, so that the tracked person P at the second position P2 can be searched. In addition, the plane of the platform 4 where the tracking camera device 1 is located is also parallel to the ground G where the tracked person P is located. Therefore, when the search device 2 determines the plane coordinates of the tracked person P, the tracking camera device 1 can simply convert and control the rotation and pitch of the tracking camera 3 to capture a close-up of the tracked object.

Please refer to Figure 4, which is a schematic diagram of the tilt angle of the whole camera in the tracking camera device of the present invention when it is placed upright. The tracking camera device 1 generally has two parts, including a body 10, usually a casing, and a tracking camera 3, which is mounted on the body 10 via a cradle 30, and the search device 2 is disposed in the body 10. When the tracking camera device 1 obtains the position of the object being tracked from the search device 2, it controls the cradle 30 to make the tracking camera 3 point to the position. The so-called upright placement means that the bottom of the tracking camera device 1 faces the center of the earth. In other words, the normal vector N of the platform 4 is parallel and in the same direction as the Z axis of the tracking camera 3, but facing away from the center of the earth. Furthermore, the embodiment of FIG. 4 is applied to the scene of FIG. 3, in which it can be seen that the visual axis 2A of the search device 2 rotates away from the tracking camera 3, that is, the tracking camera device 1 is set on a higher platform 4.

Please refer to Figure 5, which is a schematic diagram of the tilt of the full-body camera inside the tracking camera device when it is inverted on the ceiling. In order to perform tracking photography tasks in places such as theaters, performance halls, and conference halls, the tracking camera device 1 is also located at a higher position to avoid the backs of the audience and listeners, so it is also a common setting to invert on the ceiling 5, so the search device 2 also needs to face the stage or booth. Since the tracking camera device 1 is inverted, the normal vector N of the ceiling 5 is parallel and in the same direction as the Z axis of the tracking camera 3, but points to the center of the earth, while the search device 2 rotates downward in the entire space, that is, the visual axis 2A of the search device 2 is deflected in the direction of the tracking camera 3.

Please refer to FIG6 for a schematic diagram of the structure of the search device of the tracking photography device of the present invention. The search device 2 includes a first component 21, which is disposed inside the main body 10 (FIG. 4, FIG. 5) and connected to the main body 10. The first component 21 is further connected to a second component 22 via a pivot 23. The second component 22 is deflected upward or downward relative to the first component 21. The first component 21 and the second component 22 as a whole serve as a mounting frame. The search device 2 also has a main board 20 fixed on the second component 22, on which a lens 20a and a lens 20b for searching are provided. Generally speaking, one is a wide-angle lens and the other is a standard lens, and their respective visual axes are roughly parallel, or both are standard lenses, but one visual axis is biased to the left and the other is biased to the right, and their respective shooting areas are partially overlapped, so that two lenses with narrower viewing angles can form an effect similar to a wide-angle viewing angle. In addition, the second component 22 has a lever 22a extending toward the visual axis of the lens (20a, 20b). By operating the lever 22a, the user can adjust the second component 22 to deflect upward or downward, thereby deflecting the visual axis of each lens (20a, 20b) upward or downward. In addition, the second component 22 also has a second positioning portion 24, including a bolt body 240, which is screwed into a hole structure 241 located on the second component 22, and the bolt body 240 is abutted against the support arm 210 of the first component 21 to fix the rotation angle of the second component 22.

Please refer to Figure 7, which is a front view of the search device in the tracking photography device of this invention. The first component 21 further extends a support arm 210, and the second component 22 is a swing frame that is hinged to the support arm 210 through a pivot 23. In addition, the support arm 210 has a first positioning portion 210a, which is usually a concave structure, and the second component 22 is provided with a second positioning portion 24, which is usually a convex structure. The convex second positioning portion 24 and the concave first positioning portion 210a are mutually engaged to achieve the effect of mutual fixing and positioning. Figure 7 shows it in the form of a partial cross-section. The second positioning portion 24 includes a bolt body 240, which is screwed into a hole structure 241 located on the second component 22.

Please refer to Figure 8, which is a cross-sectional view of the plug body of the second positioning part in the tracking photography device of this invention. The plug body 240 has a spiral body 240b and a hollow structure. One end of the spring 240c disposed therein faces the inside of the spiral body 240b, and the other end faces outward and abuts against a roller 240a. The roller 240a is the protruding part of the second positioning part 24 mentioned above. The elastic force provided by the spring 240c enables the roller 240a to stably abut against the first positioning part 210a (Figure 7).

Please refer to Figure 9, which is a schematic diagram of the exploded mounting bracket in the tracking camera device of this invention. It more clearly reveals the relative position and connection relationship between the pivot 23 and the first and second components (21, 22). As for the adjustment of the angle of the second component 22, the user can directly manually turn a lever 22a to complete it.

Please refer to Figure 10, which is a schematic diagram of the appearance of the tracking camera device of this invention when it is placed upright at a high position and a schematic diagram of the angle of the internal search device mounting frame. It can be seen that the lens (20a, 20b) of the search device 2 is facing downward, and the second component 22 is rotated by the lever 22a to drive the lens (20a, 20b) to deflect away from the tracking camera 3. If the line of sight of the lens is the front, the first positioning part 210a on the first component 21 has one front, one middle, and one rear, respectively. At this time, the rolling member 240a in the second positioning part 24 (Figure 7) is stuck in the first positioning part 210a at the rear. Please refer to Figures 3, 4 and their related descriptions for the application scene of Figure 10, which will not be repeated here.

Please refer to Figure 11, which is a schematic diagram of the appearance of the tracking camera device of this invention when placed upright at a medium height and a corresponding schematic diagram of the internal search device mounting frame angle. It can be seen that the lens (20a, 20b) of the search device 2 is not deflected but only faces forward. At this time, the rolling member 240a in the second positioning part 24 (Figure 7) is stuck in the middle of the first positioning part 210a.

Please refer to Figure 12, which is a schematic diagram of the appearance of the tracking camera device of this invention when it is placed upside down on the ceiling and a schematic diagram of the corresponding internal search device mounting angle. It can be seen that the lens (20a, 20b) of the search device 2 is facing downward, and the second component 22 is rotated by the lever 22a to drive the lens (20a, 20b) to deflect toward the tracking camera 3. At this time, the rolling member 240a in the second positioning part 24 (Figure 7) is stuck in the front first positioning part 210a. The so-called downward refers to relative to the ceiling 5. For the application scene of Figure 12, please refer to Figure 5 and its related description, which will not be repeated here.

In summary, the present invention utilizes a first component and a second component that are interconnected in a hinged and twisted manner to adjust the pitch angle of the search device, so as to achieve the premise of not changing the original posture of the tracking camera 3 (the so-called original posture refers to the extension line of the vertical axis of the tracking camera passing through the center of the earth, or the plane where the tracking camera device is installed and placed is parallel to the plane where the person/object being tracked is located), changing the pitch angle of the visual axis of the search device, so as to cover as wide a search area and range as possible. Furthermore, the first component has a plurality of first positioning portions 210a (FIGS. 9 to 12), and the rolling member 240a in the second positioning portion 24 (FIGS. 7 and 8) on the second component is used to abut against the second positioning portion 24. The second positioning portion 24 is usually concave so that the rolling member is partially sunken therein so that the rolling member is restricted, thereby fixing the relative position between the first component and the second component. The second positioning portion 24 of the present invention is in the shape of a rectangular hole, and its short side distance is slightly smaller than the diameter of the rolling member 240a to prevent the rolling member 240a from being completely sunken therein. It can be seen that this invention can be applied to many existing tracking camera equipment, especially to the search device in such equipment, so that the pitch angle of the search device can be changed to cover the widest search range while maintaining the original posture of the tracking camera 3. Therefore, this invention has made a great contribution to the relevant industries.
