[0026] Through the coordinated action of the laser 2, the rotation unit, the industrial camera 4 and the control unit, various parts of the scanned object can be automatically rotated, the scanning efficiency and the measurement accuracy are improved, the degree of automation is high, and the operation difficulty is reduced.

[0027] The user only needs to place the object within the scanning range of the scanning device, and the control unit controls the laser 2 to emit the laser beam and drives the laser 2 to rotate through the rotating unit to scan various parts of the object. At the same time, the industrial camera 4 takes real-time pictures of the projection of the laser beam on the surface of the object, and transmits the data to the control unit for processing, and finally generates high-precision three-dimensional data.

[0028] As an optional implementation, the angle between the optical axes of the two industrial cameras 4 is 19°, so that the two industrial cameras 4 can cover the scanning range of the laser 2 without blind spots, further improving the integrity and accuracy of the scanning.

[0029] As an optional implementation, the rotating unit includes a stepping motor 3 , and the laser 2 is connected to the driving end of the stepping motor 3 via a first mounting seat 5 .

[0031] The stepper motor 3 is a driving source, which can drive the laser 2 to rotate so as to scan various parts of the object.

[0032] As an optional implementation, it also includes a structural beam 7 , which is detachably connected to the mounting base plate 11 , and the industrial camera 4 is connected to the structural beam 7 via a second mounting seat 6 .

[0033] Furthermore, the structural beam 7 is connected to the mounting base plate 11 by bolts, which is convenient for assembly and disassembly. The second mounting seat 6 is used to mount the industrial camera 4 .
