Description

Technical Field

[0001] The present application relates to the field of image communication, and in particular to a multi-viewing angle image acquisition device. Background Art

[0002] There are two main methods for acquiring multi-view images of plants: artificial active surround acquisition and image acquisition based on plant rotation. Artificial active surround acquisition means that the plant is placed in the middle and the image is taken by artificially surrounding the plant. The existing artificial active surround acquisition method has certain flexibility due to manual operation, but it is laborious, has poor repeatability and low efficiency. Image acquisition based on plant rotation is to place the plant on a rotating device such as a turntable and use one or more cameras to capture images of the plant at equal time intervals.

[0003] The patent document with announcement number CN212804985U discloses a multi-view image acquisition device, which includes a bracket with a sample stage, located on one side of the sample stage, and is also provided with a camera device and a lighting device, wherein the camera device includes a plurality of mutually matched camera connecting frames with an elongated main body I and a camera movably arranged on the camera connecting frame in the extension direction of the main body I, and the lighting device includes a plurality of mutually matched lighting connecting frames with an elongated main body II and a light source movably arranged on the lighting connecting frame in the extension direction of the main body II, and the camera connecting frame and the lighting connecting frame are arranged in parallel. Through the adjustable structure, the arrangement of the camera device and the lighting mechanism is realized from multiple required angles, and image data acquisition and recognition from multiple angles is performed, so that multiple groups of data can be acquired, and the image data of the acquisition object can be fully identified.

[0004] The patent document with announcement number CN220896759U discloses a multi-perspective image acquisition device, which includes a stage, a hollow rotating stage, a first rotating crossbar, a camera support rod, a camera, an electric slider and a motor controller. The motor controller adjusts the rotation speed of the camera by adjusting the rotation speed of the hollow rotating stage, and adjusts the position of the camera and the shooting angle of the camera by driving the sliding and rotation of the electric slider, thereby acquiring multi-perspective images of the plant. The plant sample to be tested is fixed on the stage, and the image of the plant sample to be tested is photographed by only changing the rotation speed, position and shooting angle of the camera. Since the plant sample to be tested is in a stationary state, the leaves will not be disturbed when the plant sample to be tested is photographed. Therefore, the imaging quality of the plant image is better, and the subsequent multi-view reconstruction effect is further improved. However, the above-mentioned multi-view image acquisition device cannot adjust the distance between the shooting device and the sample. After the image acquisition is completed, it cannot assist the staff to replace the sample, and it cannot protect the sample.

[0030] The implementation principle of a multi-view image acquisition device in an embodiment of the present application is as follows: when using the device, first place the plant sample on the second clamping box 16 between the two fixing frames 59, start the shooting device 10 to capture and capture, and then start the main motor 24, the output end of the main motor 24 drives the first rotating shaft 25 to rotate, the first rotating shaft 25 drives the second gear 29 on one side of the connecting sleeve rod 30 to rotate, drives the second rotating shaft 28 on the other side of the second gear 29 to rotate, the second rotating shaft 28 drives the two second tooth plates 52 to move through the third gear 53, the second tooth plate 52 drives the linkage block 51 to move along the limiting rod 31, so that the limiting plate 20 on one side of the linkage block 51 moves, and the plant sample is limited by the two limiting plates 20, and the first rotating shaft 25 rotates When the first bevel gear 27 is moved, the first bevel gear 27 on one side of the first rotating shaft 25 is also driven to rotate, and the first rotating rod 26 on the other side of the first bevel gear 27 is driven to rotate through the first bevel gear 27. The first rotating rod 26 drives the two screw blocks 45 to move through the bidirectional screw 22. The screw block 45 drives the first clamping box 14 and the second clamping box 16 to move through the toggle block 46. Because the teeth of the two second gears 29 are relatively large, when the two screw blocks 45 just move, the second gear 29 can also drive the other second gear 29 to rotate, so that when the second clamping box 16 drives the plant sample to move, it can also limit it. Because the groove of the first fixed block 49 inside the first clamping box 14 fits with the inclined rod 13, the two first fixed blocks 49 will slide along the first The rod 48 moves, thereby moving the two first clamping plates 50 to restrict the plant sample. During operation, when one of the first fixed blocks 49 moves through the first rack 54, the first rack 54 drives the first gear 56 to rotate. The first gear 56 drives the fourth gear 57 on one side thereof to rotate through the rotating rod 55. The fourth gear 57 drives the fixed frame 59 on one side thereof to move through the first toothed plate 58. Because the moving speed of the fixed frame 59 is relatively fast, the fixed frame 59 will drive the plant sample to move onto the rotating plate 21. When the plant sample needs to rotate, the auxiliary motor 34 is started, and the output end of the auxiliary motor 34 drives the first transmission rod 35 to rotate. The first transmission rod 35 drives the transmission shaft 6 on one side of the other second sprocket 62 through the second sprocket 62 and the second chain 63. 1 rotates, the transmission shaft 61 drives the rotating plate 21 to rotate, thereby driving the plant sample to rotate, thereby completing multi-angle image acquisition, and when the first transmission rod 35 rotates, it drives the first transmission shaft 36 on one side of another first sprocket 37 through the first sprocket 37 and the first chain 38, and the first transmission shaft 36 drives the first stud 60 to rotate, and the first stud 60 drives the connecting block and the connecting block to move along the direction of the sliding rod 11, thereby driving the bracket 9 on one side thereof to move, and the bracket 9 drives the shooting device 10 to move, thereby completing the multi-angle image acquisition requirement by pulling the distance between the lens and the real object. When it is idle and the plant sample on the device needs to be protected, the auxiliary motor 34 is reversed and the above operation is repeated, but at this time, the transmission shaft 61 passes through the bevel teeth 42 on the inner shaft 41,The telescopic block 64 inside the outer shaft 43 is driven to rotate, so that the outer shaft 43 drives the threaded sleeve 44 to rotate, the threaded sleeve 44 drives the threaded plate 39 to move, and the threaded plate 39 drives the baffle 40 to move, so as to protect the plant sample. When the observation is completed and it needs to be removed, the main motor 24 is started and the above operation is repeated. However, at this time, because the two second gears 29 are disengaged, the limiting device on the second clamping box 16 will still limit the plant sample, and the bidirectional screw 22 drives the two screw blocks 45 to return to their positions. When the two screw blocks 45 just move, the fixing frame 59 will drive the plant sample to return to one side of the second clamping box 16, so that it moves with the fixing frame 59 and the second clamping box 16. When the second clamping box 1 When returning to the original position, the push rod motor 19 is started, and the output end of the push rod motor 19 drives the connecting rod 18 and the connecting piece 32 to move, so that the stabilizing block 33 on one side thereof is inserted into the connecting sleeve rod 30, and then the main motor 24 is started, and the output end of the main motor 24 drives the first rotating shaft 25 to rotate, the first rotating shaft 25 drives the connecting sleeve rod 30 to rotate, the connecting sleeve rod 30 drives the connecting piece 32 to rotate, and the connecting piece 32 drives the fixed box 17 to rotate. Because the matching block 47 and the toggle block 46 at the bottom of the second clamping box 16 are disengaged, the fixed box 17 can drive the second clamping box 16 to rotate, thereby rotating the second clamping box 16 out from between the two fixing frames 59, so that it rotates to a suitable angle, which is convenient for replacing the plant sample. Embodiment 2

[0031] The difference between this embodiment and the first embodiment is that a roller is fixedly connected to the bottom of the leg 2. When the device needs to be moved, the device is pushed to rotate the roller at the bottom of the device. The rotating roller drives the device to move, thereby changing the position of the device. Embodiment 3

[0032] The difference between this embodiment and embodiment one is that a sample storage box is fixedly connected to one side of the base plate 1. When image acquisition is required or the plants whose images have been acquired can be temporarily stored in the sample storage box for storage. When the work is completed, they can be transferred in a unified manner, thereby improving work efficiency.

[0033] The photographing device in this application is an existing device.
