Research on 3D Point Cloud Data Acquisition Technology Based on Linear Structured Light

This paper presents a new method of linear structured light scanning combining monocular and binocular. The red moving light stripe projected by miniature projector is used to replace the traditional laser, which not only reduces hardware costs but is also easier to use. In order to obtain the light plane equation with high precision, the cylindrical paper tube is scanned in the binocular system, then in the monocular system, the three-dimensional point coordinates of the object are calculated according to the principle of transmission projection geometry. Experimental results show that this method can effectively balance the requirements of accuracy and speed, and has certain practical value.
