Problems solved by technology
[0002] The commonly used equipment for three-dimensional precision measurement is to use a three-dimensional coordinate measuring machine. The measuring part used is a probe, which belongs to the contact part. This kind of contact part is powerless to the measured object of soft material, and has The data acquisition efficiency of the complex surface is very low
[0003] In order to solve this problem, non-contact measuring equipment, such as three-dimensional laser scanners, has also appeared on the market, but the accuracy of the data measured by this equipment is not high, and the equipment is also powerless to the boundary of the measured object
If a three-dimensional coordinate measuring machine or a three-dimensional laser scanner is used to obtain the outline of the object, and then a device for measuring the boundary (such as a video measuring instrument) is used to measure the boundary of the object, since the instrument for multiple measurements is not an instrument, the measured object It is difficult to unify the three-dimensional coordinate values of

Embodiment Construction
[0020] The technical solutions of the present invention will be further specifically described below through specific embodiments and in conjunction with the accompanying drawings.
[0021] Please refer to figure 1 as shown, figure 1 It is a schematic diagram of the structure and principle of the non-contact compound scanning measurement system. The non-contact compound scanning measurement system 100 comprises a high-magnification objective lens 10, a point laser 20, a cylindrical concave lens 30, a double-sided mirror 40, a digital camera 50, an eyepiece 60, a mirror 70 and a set of switching devices (not shown in the figure) ), where the point laser light generated by the point laser 20 passes through the double-sided mirror 40 and the reflected direction coincides with the optical axis of the eyepiece 60. The switching device switches the components therein according to the working requirements, so as to achieve different working states. The following are the three work...
