Embodiment 1
[0039] First, the parallel multi-line laser three-dimensional scanning system in the present invention is described, as figure 1 As shown, the measurement system is made up of two industrial cameras 1, 2, a laser projector 3 and two camera filters 9, and the laser projector 3 projects a plurality of parallel laser lines. For example, the number of the parallel laser lines is not limited to 4, and intersects with the object to be measured to form a modulated light strip. The light strip is located on the light plane in space, and is imaged on the camera CCD through perspective projection. Compared with the traditional structured light measurement system, this paper does not need to calibrate the light plane equation on the light plane 6, but only needs to use the laser plane 6 to induce the homography matrix between the left and right image planes, so the calibration between the left and right image planes The homography matrix of is the key to building a 3D measurement model.
