Research on 3D reconstruction measurement method of workpieces based on binocular line structured light

During the reconstruction process, the measured object is affected by its own reflection, environmental illumination, and other factors, resulting in a large number of mismatching points during the stereo-matching process, thus affecting the accuracy of the three-dimensional reconstruction. Aiming at the above problems, this paper adopts a scanning method combining single-line laser and binocular vision. The binocular epipolar constraint is used to obtain the initial matching points, and the optical plane constraint is added to eliminate the false matching points. The experimental results show that the 3D modeling error of the workpiece is maintained within 0.5cm, which verifies that the method has certain feasibility and good accuracy in solving problems such as mismatching.
