[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-5 The utility model provides an embodiment: a surround image acquisition device, comprising a hollow frame 1 and a loading plate 3 for carrying articles mounted on the top of the hollow frame 1, an inverted U-shaped vertical plate 2 is fixed on the top of the hollow frame 1, and a slewing ring 4 is rotatably mounted on the outer wall of one side of the inverted U-shaped vertical plate 2, and the inner diameter of the slewing ring 4 is 60cm to 100cm;

[0019] A plurality of image acquisition cameras 5 are installed in a circular shape at equal intervals on the outer wall of one side of the slewing ring 4, a rotating drive mechanism 6 for driving the slewing ring 4 to rotate is arranged on one side of the back side of the inverted U-shaped vertical plate 2, a square straight arm 7 is slidably installed on the outer wall of one side of the hollow frame 1, a right-angle arm for being fixedly connected to the outer wall of one side of the slewing ring 4 is fixed on one side of the top of the square straight arm 7, an X-axis lateral movement mechanism 10 for driving the square straight arm 7 and the slewing ring 4 to slide on the X-axis is installed on the outer wall of the hollow frame 1 below the square straight arm 7, a control panel 8 electrically connected to the input ends of the rotating drive mechanism 6 and the X-axis lateral movement mechanism 10 is installed on the outer wall of one side of the hollow frame 1, the rotating power of the rotating drive mechanism 6 is transmitted to the slewing ring 4, so that the slewing ring 4 rotates, and then the plurality of image acquisition cameras 5 revolve around the workpiece and the carrier plate 3;

[0020] The square straight arm 7 and the slewing ring 4 are driven by the X-axis lateral movement mechanism 10 to move along the extension direction of the carrier plate 3, so that the image acquisition at each position can maintain a certain overlap in the X-axis direction;

[0021] The image acquisition camera 5 converts the captured optical image into a digital signal through its own lens, and the obtained electrical signal is amplified, filtered, color corrected, etc. by its internal signal processing circuit to ensure that the final output image has good quality. Finally, the processed and collected image information is transmitted to the computer for synthesis;

[0022] A plurality of steel wheels are rotatably mounted on the outer wall of one side of the inverted U-shaped vertical plate 2 close to the slewing ring 4, and the annular surface of the steel wheels contacts the annular surface of the slewing ring 4; the rotation drive mechanism 6 includes a first servo motor 601 mounted on one side of the back of the inverted U-shaped vertical plate 2, and a rubber wheel 602 mounted on the output end of the first servo motor 601, and the annular surface of the rubber wheel 602 contacts the annular surface of the slewing ring 4. When the slewing ring 4 is working, the first servo motor 601 drives the rubber wheel 602 to rotate. Since the rubber wheel 602 contacts the outer wall of the slewing ring 4, the friction between the rubber wheel 602 and the slewing ring 4 is used to make the slewing ring 4 rotate. At this time, a plurality of image acquisition cameras 5 revolve around the loading plate 3 and the articles. During this process, the control panel 8 controls the first servo motor 601 to work according to the set direction, speed, angle, and response time, which can complete the scanning process at a faster speed while ensuring the image quality and consistency at each angle;

[0023] Two parallel and symmetrical guide rails 1002 are fixed on the back of the square straight arm 7, and a dovetail block for slidingly cooperating with the guide rails 1002 is fixed on the outer wall of one side of the hollow frame 1. The dovetail block and the guide rails 1002 serve as movement guides for the square straight arm 7 to ensure its smooth movement;

[0024] The X-axis transverse movement mechanism 10 includes a support table 9 fixed on the outer wall of one side of the hollow frame 1, a second servo motor 1001 installed at the bottom of the support table 9, and a bevel gear 1003 installed at the output end of the second servo motor 1001. The bottom end of the square straight arm 7 is fixed with a bevel rack 1004 for meshing with the second servo motor 1001. During the sliding action of the square straight arm 7, the rotational power of the second servo motor 1001 is converted into a linear horizontal movement of the bevel rack 1004 through the bevel gear 1003, that is, the bevel rack 1004, the square straight arm 7 and the slewing ring 4 slide horizontally. This structure ensures all-round coverage of the scanned object and the integrity of image acquisition, and will not miss important parts due to limitations of angles and equipment positions.

[0025] When the embodiment of the present application is in use, the staff first places the object to be imaged on the carrier plate 3 and ensures that it is placed stably, then the staff turns on the image acquisition camera 5 to work, and turns on the X-axis lateral movement mechanism 10 and the rotation drive mechanism 6 through the control panel 8 to work. During this process, the rotary power of the rotation drive mechanism 6 is transmitted to the slewing ring 4, so that the slewing ring 4 rotates on itself, and then multiple image acquisition cameras 5 revolve around the workpiece and the carrier plate 3, ensuring that each image acquisition camera 5 can obtain accurate image acquisition at each angle, and at the same time, when the slewing ring 4 rotates slowly During the process, the X-axis transverse movement mechanism 10 drives the square straight arm 7 and the slewing ring 4 to move along the extension direction of the carrier plate 3, so that the image acquisition at each position can maintain a certain overlap in the X-axis direction, which is very beneficial for subsequent image stitching and processing, and can reduce the deficiency of overlapping areas and ensure the continuity and integrity of the panoramic image. Compared with the slight jitter or instability that may exist in handheld operation, the mechanical drive of the device can provide higher stability and repeatability, thereby ensuring the accuracy of the scan. Image acquisition at each angle is completed under fixed conditions, reducing additional errors introduced due to human factors.
