[0002] The 3D scanning device is mainly composed of a 3D laser scanner, a computer, a power supply system, a bracket and system supporting software. The 3D laser scanner is the core. It scans the 3D point cloud data on the surface of an object through the 3D laser scanner. Therefore, it can be used to obtain high-precision and high-resolution digital terrain models. It has the characteristics of speed, non-contact, real-time, dynamic, active, high-density, high-precision, digitization and automation.

[0003] However, existing 3D laser scanners are mostly installed through fixed brackets and perform comprehensive scanning by rotating objects. However, objects are prone to shifting when rotating, which affects the scanning results. Existing 3D laser scanners also mostly use a single set of laser scanning, which has a small scanning area and reduces work efficiency. In order to address the shortcomings of the existing technology, we propose a multi-point 3D scanning device. Utility Model Content

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 3 As shown, a multi-point three-dimensional scanning device includes a scanning device body 1. A fixed column 2 is detachably installed at the bottom center of the inner wall of the scanning device body 1. The driving motor 3 is started by a staff member, and the output end of the driving motor 3 rotates to drive the driving wheel 4 to rotate, and drives the driven wheel 5 through friction transmission. Then the driven wheel 5 drives the connecting tube 6 to drive the movable wheel 7 to drive the arc bracket 8 to start rotating around the fixed column 2. The current position of the driven wheel 5 is fixed by the magnetic attraction of the first magnetic column 15 on the driven wheel 5 and the second magnetic column 16 at the new position, so that the arc bracket 8 stops at the current position, and the movable wheel 7 can drive the arc bracket 8 to scan around the object. The object itself is placed on the anti-slip pad 17 on the fixed column 2. The object does not need to be rotated for a comprehensive scan, and the object has no displacement, so the scanning positioning is more precise and the data is more accurate.

[0023] like Figure 4 As shown, a fixed scanning head 9 is detachably installed on the top of the inner side of the arc bracket 8, and a slide groove 10 is opened on one side of the arc bracket 8. Two scanning components 11 are arranged inside the slide groove 10. The laser scanning heads 12 contained in the two scanning components 11 cooperate with the fixed scanning head 9 to perform a comprehensive scan on one side of the object to be scanned. Multi-point scanning collects data more densely, the scanning results are more accurate, the scanning area is increased, and the scanning is faster. When it is necessary to adjust the position of the scanning component 11 on the arc bracket 8, the staff loosens the fastening bolts 13, and then pulls the laser scanning head 12 to adjust its position on the arc bracket 8. After the adjustment is completed, the fastening bolts 13 are tightened to fix the laser scanning head 12 to the adjusted new position. The scanning angle of the laser scanning head 12 on the arc bracket 8 can be changed by adjusting the position of the laser scanning head 12 on the arc bracket 8, which is convenient for the staff to operate. The scanning angle is changeable, which can meet the scanning requirements of objects with different rules and is more practical.

[0024] How it works

[0025] It should be noted that the utility model is a multi-point three-dimensional scanning device. When in use, the staff first places the object to be scanned on the anti-slip mat 17, and then starts the fixed scanning head 9 and the laser scanning head 12 to scan the object to be scanned. After the fixed scanning head 9 cooperates with the laser scanning head 12 to scan one side of the object, the driving motor 3 is started, and the output end of the driving motor 3 rotates to drive the driving wheel 4 to rotate. The driving wheel 4 drives the driven wheel 5 to rotate through friction transmission. The driven wheel 5 drives the connecting tube 6 to drive the movable wheel 7 to rotate outside the fixed column 2. The movable wheel 7 drives the arc bracket 8 to start rotating around the fixed column 2. At the same time, when the driven wheel 5 rotates, it drives the first magnetic column 15 to rotate. The first magnetic column 15 at the current position and the second magnetic column 16 at the new position are attracted by magnetic force. At this time, the driving motor 3 is turned off, and the movable wheel 7 drives the arc bracket 8 to stop at the new position. The fixed scanning head 9 cooperates with the laser scanning head 12 to scan one side of the object again, and the above steps are repeated until the movable wheel 7 drives the arc bracket 8 to drive the fixed scanning head 9 and the laser scanning head 12 to scan around the object for one circle, so as to achieve the purpose of comprehensive scanning of the non-rotating object.

[0026] When the side of the object is an irregular protrusion, tighten the fastening bolt 13, the fastening bolt 13 is no longer locked on the arc bracket 8, pull the laser scanning head 12, and push the two laser scanning heads 12 on the arc bracket 8 to the upper and lower sides of the protrusion of the object, and then tighten the fastening bolt 13. The fastening bolt 13 presses the gasket 14 again and locks it on the arc bracket 8, thereby adjusting the laser scanning head 12 to a new position on the arc bracket 8, and then scanning the object, thereby achieving the purpose of adjusting the position of the laser scanning head 12 on the arc bracket 8 and changing the scanning angle of the laser scanning head 12.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
