[0002] The 3D body scanner consists of a scanner body and a control cabinet. The scanner body serves as the imaging unit, while the control cabinet serves as the operating control unit. The scanner body is constructed from multiple columns arranged in a circular pattern, equipped with cameras and spotlights. The cameras capture and scan the body through this circular pattern to form a 3D human model. However, due to the existing circular arrangement of multiple columns, the grating spotlights are located close to the center, resulting in a smaller illumination area and a smaller enclosure, which can only capture people and objects of a certain size. To ensure that the entire 3D body scanner's footprint remains constant while also increasing the illumination area to enable the 3D body scanner to scan larger people and objects, this solution was developed.

[0025] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description.

[0026] like Figures 1-8 As shown, this embodiment provides a square multi-view three-dimensional human body scanner, including a control cabinet 1, a bottom plate 2, a top plate 3, side baffles 4, thirteen first columns 5 and four second columns 6.

[0027] Thirteen first columns 5 are arranged in a circular pattern, and four second columns 6 are arranged in a matrix outside the thirteen first columns 5. The first columns 5 have six first mounting holes, in which cameras 7 are installed. The second columns 6 have three second mounting holes and two third mounting holes, with the third mounting holes located between the two second mounting holes. Spotlights 8 are installed in the second mounting holes, and cameras 7 are installed in the third mounting holes. The first and second columns 5, 6 are hollow columns, and their bottom surfaces are provided with wire entry holes 22.

[0028] Preferably, the number of the first column 5, the second column 6, the first mounting hole, the second mounting hole and the third mounting hole can be adjusted according to actual conditions.

[0029] In this embodiment, each camera 7 takes two groups of photos simultaneously, one group takes RGB color photos for reconstructing texture maps, and the other group takes grating photos projected by structured light for reconstructing grid information; the frame rate of a single camera 7 is 30HZ, and the single capture time of the camera 7 array (RGB camera 7 + structured light, a total of 2 groups of photos) is 0.1 second, which can capture people or scenes that are prone to shaking.

[0030] The bottom surfaces of the first column 5 and the second column 6 are detachably connected to the base plate 2. Specifically, a wire groove 21 is formed on the lower surface of the base plate 2. The bottom of the wire groove 21 is formed with wire holes corresponding to the first column 5 and the second column 6. The lines are arranged in the wire groove 21 and extend into the interior of the first column 5 and the second column 6 through the wire holes and the wire entry holes 22. The horizontal cross-section of the base plate 2 is projected into a matrix, and an encirclement is provided in the middle of the base plate 2. A notch 24 is provided on one side of the base plate 2. The notch 24 (i.e., the entrance) is used to allow people or objects to enter the encirclement. The control cabinet 1 is provided on the base plate 2, and the control cabinet 1 is located on the side away from the notch 24. In this embodiment, the connection method selected between the bottom surfaces of the first column 5 and the second column 6 and the base plate 2 is plug-in. A convex frame 23 is provided above the wire hole of the base plate 2. The convex frame 23 is fixed to the base plate 2 by bolts or screws. A clamping platform 231 extends outward on both sides of the corresponding convex frame 23. L-shaped plates are connected to both sides of the bottom surface of the first column 5 or the second column 6. The transverse parts of the two L-shaped plates face each other. The distance between the transverse parts of the two L-shaped plates is equal to or greater than the length of the convex frame 23 and is less than the distance between the side surfaces of the two clamping platforms 231. The distance between the lower surface of the clamping platform 231 and the base plate 2 is equal to or greater than the thickness of the transverse part of the L-shaped plate. In this embodiment, the distance between the lower surface of the clamping platform 231 and the base plate 2 is equal to the thickness of the transverse part of the L-shaped plate; the first column 5 or the second column 6 is fixed by two L-shaped plates being clamped between the lower surface of the clamping platform 231 and the upper surface of the base plate 2.

[0031] This embodiment provides a more preferred method, such as Figure 5 As shown, a clamping sleeve 9 is provided on the bottom surface of the first column 5 or the second column 6, and the clamping sleeve 9 includes a U-shaped plate, and the bottom surface of the U-shaped plate has a connecting plate 91, and the connecting plate 91 has a bayonet 92 on the side facing the opening of the U-shaped plate. The shape of the bayonet 92 is adapted to the shape of the convex frame 23, and the thickness of the connecting plate 91 is equal to or less than the distance between the lower surface of the platform and the bottom plate 2. By connecting the three sides of the U-shaped plate to the three side surfaces of the bottom of the first column 5 or the second column 6, a certain distance of the thickness of the card platform 231 is left inside the connecting plate 91 and the first column 5 or the second column 6, and then the bayonet 92 of the connecting plate 91 is inserted into the side wall of the convex frame 23 by plugging, and is locked under the card platform 231 to achieve plugging.

[0032] The top surfaces of the first columns 5 and the second columns 6 are detachably connected to the top plate 3. Specifically, the lower surface of the top plate 3 has seventeen limiting grooves 31, which are respectively adapted to the upper ends of the thirteen first columns 5 and the four second columns 6. The first columns 5 and the second columns 6 extend into the limiting grooves 31, which limits the movement of the top plate 3, and there is no need to set up additional connecting parts between the top plate 3 and the first columns 5 and the second columns 6.

[0033] A side baffle 4 is provided on the outer side of the top plate 3 and the bottom plate 2 , and the side baffle 4 is connected to the side walls of the top plate 3 and the bottom plate 2 by screws.

[0034] In this embodiment, four second columns 6 are arranged in a matrix outside the plurality of first columns 5 arranged in a ring, thereby increasing the distance between the four second columns 6 and the center of the area enclosed by the plurality of first columns 5. As a result, the distance between the spotlights 8 installed on the second columns 6 and the center of the area enclosed by the plurality of first columns 5 is increased. Compared with a three-dimensional body scanner with the same footprint and only provided with a plurality of first columns 5, the three-dimensional body scanner in this embodiment has a larger illumination area, allowing the formed encirclement to be larger, allowing for the capture of larger people or objects.

[0035] The installation steps of a square multi-view three-dimensional human body scanner in this embodiment are as follows: the cameras 7 in the first column 5 and the second column 6 are pre-installed, the base plate 2 is installed, and then the cables are laid in the wire groove 21 of the base plate 2, the convex frame 23 is installed on the base plate 2, and the L-shaped plate is installed under the first column 5 and the second column 6. The first column 5 and the second column 6 are plugged into the convex frame 23 in turn, the cables are moved into the first column 5 and the second column 6 and connected to the terminals, the positioning code is affixed to the first column 5, the top plate 3 is installed, the side baffle 4 is installed, the monitoring is installed on the top plate 3, and then the spotlight 8 is installed on the second column 6. The top cover is installed, the light strip power supply in the encirclement is turned on, the floor stickers and curtains are installed, and finally the control cabinet 1 is connected to each cable line.
