金属框架全尺寸3D检测
The 3D information obtained by laser triangulation technology has the characteristics of high resolution and high accuracy , and its basic principle is shown in Figure 4. A laser triangulation system usually consists of a laser transmitter and a camera. The laser emitter emits point laser or line laser to the metal workpiece in the high temperature state to be measured from a certain angle, and then the CCD photodetector receives the laser spot or stripe on the surface of the metal part. The change of the size and morphology of the measured object can be reflected by the position change of laser spot and fringe captured by the camera.
