[0022] The camera support mechanism 2 includes a support frame 201, with a lifting screw 202 rotatably connected inside the support frame 201. The support frame 201 is fixedly installed on the top of the base 1. The bottom end of the lifting screw 202 is rotatably connected to the base 1, allowing the support frame 201 to support the lifting screw 202. A lifting motor 203 is fixedly connected to the bottom end of the lifting screw 202. The lifting motor 203 is detachably connected to the inner wall of the base 1 by bolts. The output shaft end of the lifting motor 203 is connected to the lifting screw 202, enabling the lifting motor 203 to drive the lifting screw 202 to rotate, thereby allowing for lifting. A lifting nut seat 204 is threaded onto the lifting screw 202. 4. Multiple guide rods 205 are fixedly connected to the base 1. A horizontal plate 206 is fixedly connected to the top of each guide rod 205. The bottom ends of the guide rods 205 are fixedly connected to a lifting nut seat 204. The top of the lifting nut seat 204 passes through the support frame 201 and is fixedly connected to the horizontal plate 206. A bushing is provided between the guide rods 205 and the support frame 201 to protect the hole wall between them. An electric rotary table 208 and a counterweight 207 are fixedly connected to both ends of the horizontal plate 206. The counterweight 207 ensures that the center of gravity of the horizontal plate 206 is directly above the base 1, improving operational stability. The electric rotary table 208 is driven by a motor (servo motor or stepper motor). The electric rotary table 208 uses a transmission mechanism such as a worm gear, planetary gear, or helical gear to achieve 360° rotation and support arbitrary angle segmentation and positioning. A through hole 210 is provided in the center of the electric rotary table 208, allowing the upper body of the person being collected to enter, thus enabling the camera to rotate around the face. An arc-shaped base 209 is mounted on the electric rotary table 208, with three mounting brackets 211 on its top. These brackets are fixedly mounted on the arc-shaped base 209 and hang vertically from top to bottom, allowing for the placement of industrial cameras, SLR cameras, and infrared capture cameras, facilitating the processing of facial data. In the acquisition process, a connecting plate 212 is fixedly connected between each two adjacent placement racks 211. A limit plate 213 is fixedly connected to one end of each placement rack 211. Each placement rack 211 has a guide groove, and a clamping screw 214 is rotatably connected inside the guide groove. A clamping knob 217 is fixedly connected to the end of the clamping screw 214. A clamping plate 215 is threaded onto the clamping screw 214. Rubber pads 216 are fixedly connected to both the clamping plate 215 and the limit plate 213. The clamping plate 215 is slidably connected to the guide groove. The rubber pads 216 are set on the opposite side surface of the clamping plate 215 and the limit plate 213, so that the camera can be clamped by the rubber pads 216 to prevent damage to the camera.

[0023] Please see Figure 1 and Figure 4The braking mechanism 4 includes a movable rod 401, with an anti-detachment block 403 fixedly connected to the top end of the movable rod 401 and a foot 402 fixedly connected to the bottom end of the movable rod 401. A U-shaped groove 406 is provided on the base 1, with two horizontal grooves and one vertical groove. The two horizontal grooves can engage and fix the elastic rod 405, while the vertical groove allows the elastic rod 405 to move up and down. The movable rod 401 is movably connected to the interior of the base 1. A rotating sleeve 404 is rotatably connected to the movable rod 401, and the elastic rod 405 is fixedly connected to the rotating sleeve 404. The elastic rod 405 can utilize its own elasticity to engage and fix the elastic rod 405. The elastic rod 405 is fixed inside the U-shaped groove 406 and extends through the U-shaped groove 406 and partially to the outside of the base 1. By rotating the elastic rod 405, the elastic rod 405 can enter the vertical groove from the top horizontal groove of the U-shaped groove 406. Then, the elastic rod 405 is pushed down. The movement of the elastic rod 405 drives the rotating sleeve 404 to move. The movement of the rotating sleeve 404 drives the movable rod 401 to move, so that the foot 402 is pressed against the ground. Then, the elastic rod 405 is rotated into the horizontal groove at the bottom of the U-shaped groove 406 for locking and fixing, so that the universal wheel 3 can be braked and the stability during use can be improved.

[0024] During operation, an industrial camera, a DSLR camera, and an infrared capture camera are mounted on three mounting brackets 211. Then, the clamping knob 217 is rotated, causing the clamping screw 214 to rotate. The clamping screw 214 then moves the clamping plate 215, which, in conjunction with the limiting plate 213, clamps and secures the camera. Next, the lifting motor 203 drives the lifting screw 202 to rotate, which in turn moves the lifting nut seat 204. This movement of the lifting nut seat 204 then moves the guide rod 205, which in turn moves the horizontal plate 206. The horizontal plate 206 then moves the electric rotary table 208, positioning the person being scanned inside the through-hole 210, thus placing the camera around the outer perimeter of their face. The electric rotary table 208 then rotates the camera to perform a comprehensive facial scan. This method is more efficient than manual handheld camera scanning, reduces the workload of staff, and effectively improves data collection efficiency.
