Description

Technical Field

[0001] This utility model relates to the field of camera photography testing technology, specifically to a camera photography platform. Background Technology

[0002] In the process of photographing electronic product samples, different products have specific requirements for parameters such as light color temperature, light intensity, and camera field of view. Therefore, it is necessary to precisely adjust the camera's position on the X, Y, and Z axes and optimize parameters such as the height and angle of the light source. However, existing shooting platforms have the following technical shortcomings:

[0003] 1. Insufficient adjustment precision: The camera's three-axis (X, Y, Z) displacement parameters cannot be adjusted with high precision, making it difficult to accurately control the shooting field of view and composition. The height adjustment of the light source only supports coarse-grained adjustments such as 100mm and 200mm, and cannot achieve stepless adjustments such as 1mm, 5mm or 10mm, affecting the accuracy of lighting.

[0004] 2. Existing photography platforms cannot freely adjust the height and angle of the light source according to the optical characteristics of different objects (such as material reflectivity and surface texture). This can easily lead to: (1) Hard light sources or improper lighting angles can easily produce obvious shadows, affecting image uniformity. (2) Light pollution interference: Ambient light (such as indoor stray light) cannot be effectively isolated, resulting in color casts or uneven brightness in the sample images. (3) When the light intensity is insufficient, the color reproduction of the sample images is reduced, especially when compared with a standard color chart in post-processing, the deviation is more significant.

[0005] 3. Limited image quality: Existing platforms are unable to provide a uniform lighting environment, resulting in uneven brightness and color distortion in the captured images, which affects subsequent image analysis and product display effects. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide a camera imaging platform. This invention can continuously and steplessly adjust the height and angle of the light source according to the optical characteristics of different photographed objects, providing a uniform lighting environment, ensuring uniform illuminance distribution on the surface of the subject and providing a bright environment, effectively avoiding the generation of local shadows and preventing light pollution, thus meeting the refined lighting needs of different shooting scenarios.

[0007] This utility model embodiment provides a camera photography platform, including a breadboard. A vertical adjustment mechanism is provided on one side of the breadboard. The vertical adjustment mechanism is movably configured with a camera moving mounting platform and a ring light source in the height direction. Rotatable planar light sources are symmetrically arranged on both sides of the camera moving mounting platform. Locking structures for fixing the rotation angle of the planar light sources are detachably connected to both sides of the planar light sources. The planar light sources can rotate around the connecting axis of the locking structures. The locking structures are fixed to the breadboard by telescopic rods.

[0008] In one embodiment, the vertical adjustment mechanism includes a first column and a second column located on the side of the breadboard. Both the first column and the second column are equipped with lifting guide rail systems. The first column is connected to the camera moving and mounting platform through the corresponding lifting guide rail system, and the second column is connected to the ring light source through the corresponding lifting guide rail system.

[0009] In one embodiment, the camera moving mounting platform includes a connector connected to a vertical adjustment mechanism, the other end of which is connected to an XY manual platform, and a precision lifting adjustment device is provided on the connection panel of the XY manual platform.

[0010] In one embodiment, the XY manual platform includes a Y-axis slide rail and a Y-axis slider mounted on the Y-axis slide rail and capable of sliding horizontally along the Y-axis slide rail. An X-axis slider is slidably nested inside the Y-axis slider. The X-axis slider is capable of sliding in a horizontal direction perpendicular to the extension direction of the Y-axis slide rail. The X-axis slider is connected to the connecting panel.

[0011] In one embodiment, both the Y-axis slide rail and the Y-axis slider are marked with scale lines.

[0012] In one embodiment, the precision lifting adjustment device includes a ball screw connected to a connecting panel, the ball screw being connected to the output end of a drive motor, and a nut being slidably mounted on the ball screw.

[0013] In one embodiment, brackets are provided on both sides of the planar light source, and manual knobs with connecting shafts are provided on the brackets. The manual knobs are connected to the middle of the corresponding side of the planar light source through the connecting shafts. By tightening the manual knobs, the brackets on both sides of the planar light source are clamped and fixed to both sides of the planar light source, thereby locking the rotation angle of the planar light source.

[0014] In one embodiment, the bracket has a through hole for the connecting shaft to pass through, the connecting shaft has an external thread, and the two sides of the planar light source have threaded holes that match the connecting shaft. The connecting shaft of the manual knob passes through the corresponding through hole and is threadedly connected to the corresponding threaded hole.

[0015] In one embodiment, an angle scale is provided on the bracket at the connection point with the planar light source.

[0016] In one embodiment, the telescopic rod includes at least two stages of pipe diameter, with each stage of pipe diameter being sequentially connected and a locking buckle provided at the joint of adjacent stages of pipe diameter.

[0017] The beneficial effects of the camera capturing platform provided in this embodiment of the utility model are as follows:

[0018] This invention utilizes a multi-source lighting system to adapt to the optical properties of different materials. The combination of a ring light source and dual-sided planar light sources provides main illumination from top to bottom, while the dual-sided planar light sources can rotate freely (0-90°) and lock at their angles, effectively reducing shadows and reflections. By adjusting the height and angle of the light sources, it avoids imaging problems (such as localized overexposure or excessive shadows) caused by fixed light sources in existing technologies. The directional illumination from the planar and ring light sources effectively reduces stray light interference from the environment, ensuring accurate color reproduction in the sample images and avoiding color casts or uneven brightness.

[0019] This invention utilizes a graduated XY manual slide and a ball screw-driven Z-axis precision lifting adjustment device to achieve millimeter-level (X / Y axis) or even micrometer-level (Z axis) fine-tuning of the camera position, ensuring precise control of the shooting field of view and composition.

Detailed Implementation

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting the present utility model. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting the present utility model.

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0035] like Figure 1 and Figure 2As shown, a camera imaging platform includes a breadboard 1. A vertical adjustment mechanism 2 is provided on one side of the breadboard 1. A camera moving mounting platform 3 and a ring light source 4 are movably arranged in the vertical adjustment mechanism 2 in the height direction. The camera moving mounting platform 3 is placed inside the ring light source 4, which provides illumination from top to bottom. Rotatable planar light sources 5 are symmetrically arranged on both sides of the camera moving mounting platform 3. The planar light sources 5 provide illumination from the sides. The arrangement of the ring light source 4 and the planar light sources 5 provides a uniform lighting environment, ensuring uniform illuminance distribution on the surface of the subject and providing a bright environment, effectively avoiding the generation of local shadows. Locking structures for fixing the rotation angle of the planar light sources 5 are detachably connected to both sides of the planar light sources 5, and the planar light sources 5 can rotate around the connecting shaft 6 of the locking structure. The locking structure is fixed to the breadboard 1 by a telescopic rod 7.

[0036] like Figure 6 As shown, in this embodiment, the breadboard 1 is square, and the object to be photographed can be placed on the breadboard 1. The surface of the breadboard 1 has evenly distributed M6 threaded holes and is equipped with feet.

[0037] like Figure 3 , 4 As shown in Figure 5, the vertical adjustment mechanism 2 includes a first column 8 and a second column 9 located on the side of the breadboard 1. Both the first column 8 and the second column 9 are equipped with lifting guide rail systems. The first column 8 is connected to the camera moving installation platform 3 through the corresponding lifting guide rail system, and the second column 9 is connected to the ring light source 4 through the corresponding lifting guide rail system.

[0038] A first gimbal 26 and a second gimbal 27 are slidably mounted on the first column 8 and the second column 9, respectively. The first gimbal 26 is connected to the camera moving and mounting platform 3, and the second gimbal 27 is connected to the ring light source 4. Both the first gimbal 26 and the second gimbal 27 are equipped with handwheel handles 28. Each of the first column 8 and the second column 9 has a slide rail with a constant force spring, and the handwheel handles 28 are connected to the corresponding slide rail. Rotating the corresponding handwheel handle 28 can move the camera or the ring light source 4 up and down.

[0039] like Figure 8 As shown, the camera mobile mounting platform 3 includes a connector 10 connected to the first gimbal 26 of the vertical adjustment mechanism 2. The other end of the connector 10 is connected to the XY manual platform 24. A precision lifting adjustment device 25 is provided on the connection panel 11 on the XY manual platform 24.

[0040] like Figure 9As shown, the XY manual platform 24 includes a Y-axis slide rail 12 and a Y-axis slider 13 mounted on the Y-axis slide rail 12 and capable of sliding horizontally along the Y-axis slide rail 12. An X-axis slider 14 is slidably nested inside the Y-axis slider 13. The X-axis slider 14 can slide in a horizontal direction perpendicular to the extension direction of the Y-axis slide rail 12. The X-axis slider 14 is connected to the connecting panel 11.

[0041] Both the Y-axis slide rail 12 and the Y-axis slider 13 are marked with scale lines.

[0042] Preferably, a Y-direction knob 30 is provided on the first side of the Y-axis slider 13, which is adjacent to the Y-axis slide rail 12, and the end of the Y-direction knob 30 can abut against the Y-axis slide rail 12; an X-direction knob 29 is provided on the second side of the Y-axis slider 13, which is adjacent to the X-axis slider 14, and the X-direction knob 29 can abut against the X-axis slider 14. When it is necessary to adjust the displacement of the camera in the Y-axis direction, first loosen the Y-direction knob 30, then move the Y-axis slider 13 along the Y-axis slide rail 12 to the predetermined position, and finally tighten the Y-direction knob 30; in the tightened state, the end of the Y-direction knob 30 forms an abutment with the side of the Y-axis slide rail 12, thereby achieving the positioning and locking of the Y-axis slider 13. Similarly, fine adjustment in the X-axis direction is achieved by operating the X-direction knob 29, and its working principle is the same as that of fine adjustment in the Y-axis direction.

[0043] The precision lifting adjustment device 25 includes a ball screw 15 connected to the connecting panel 11. The ball screw 15 is connected to the output end of the drive motor 16. A nut 17 is slidably mounted on the ball screw 15, and the nut 17 can be fixedly connected to the camera, so that the linear movement of the nut 17 can drive the camera to make fine adjustments to its height along the Z-axis (vertical direction). When the camera height needs to be adjusted, the drive motor 16 outputs rotational motion, driving the ball screw 15 to rotate. Since the nut 17 and the ball screw 15 form a helical transmission pair through the balls, the rotational motion of the ball screw 15 is converted into the linear displacement of the nut 17. By controlling the rotation direction of the drive motor 16, the raising or lowering of the nut 17 can be adjusted, thereby driving the camera to achieve lifting and lowering motion.

[0044] like Figure 7 and Figure 11 As shown, brackets 18 are provided on both sides of the planar light source 5. Manual knobs 19 with connecting shafts 6 are provided on the brackets 18. The manual knobs 19 are connected to the middle of the corresponding side of the planar light source 5 through the connecting shafts 6. By tightening the manual knobs 19, the brackets 18 on both sides of the planar light source 5 are clamped and fixed to both sides of the planar light source 5, thereby locking the rotation angle of the planar light source 5.

[0045] The bracket 18 has a through hole 20 for the connecting shaft 6 to pass through. The connecting shaft 6 has an external thread. The two sides of the planar light source 5 have threaded holes that match the connecting shaft 6. The connecting shaft 6 of the manual knob 19 passes through the corresponding through hole 20 and is threadedly connected to the corresponding threaded hole.

[0046] An angle scale 21 is provided on the bracket 18 at the connection point with the planar light source 5.

[0047] In this embodiment, the bracket 18 is U-shaped, and the angle scale 21 is provided at the top of both ends of the bracket 18. A mark is provided at the middle of one side of the planar light source 5. When the planar light source 5 is rotated, the rotation angle of the planar light source 5 can be determined by referring to the mark and the angle scale 21.

[0048] Multiple through holes 20 are provided at intervals in the vertical direction at both ends of the bracket 18. The diameter of the through holes 20 is slightly larger than the diameter of the connecting shaft 6 to allow the connecting shaft 6 to move freely within the through holes 20. When it is necessary to adjust the illumination angle of the planar light source 5, firstly, the connecting shaft 6 is partially unscrewed from the threaded hole by manually turning the knob 19 to release the clamping effect of the bracket 18 on the planar light source 5. Then, the planar light source 5 is rotated to the predetermined angle. During this process, the manual knob 19 and the connecting shaft 6 rotate synchronously with the planar light source 5. Finally, the manual knob 19 is tightened to clamp and fix the brackets 18 on both sides of the planar light source 5, thereby locking the rotation angle of the planar light source 5.

[0049] The bottom of the bracket 18 is fixedly connected to the telescopic rod 7, and the other end of the telescopic rod 7 is fixed to the breadboard 1 through the base 31.

[0050] like Figure 10 The telescopic rod 7 shown includes at least two stages of diameter tubes 22, which are sequentially connected. A locking buckle 23 is provided at the joint of adjacent stages of diameter tubes 22 to achieve telescopic adjustment and fixation.

[0051] Specifically, the various diameter sections 22 are made of aluminum alloy or carbon fiber to ensure lightweight construction and structural strength, and the locking buckle 23 is a textured silicone type. In this embodiment, the large-diameter section 22 is threadedly connected to the locking buckle 23, and the small-diameter section 22 is positioned by the silicone of the locking buckle 23, ensuring that the telescopic rod 7 can be adjusted to any length from 185 to 488 mm.
