Cross-line structured light binocular vision scanning device

Abstract

The invention provides a cross-line structured light binocular vision scanning device. A support rod is vertically arranged at the edge of a support platform, a slide rail is provided on the side of the support rod, and a first connecting member and a second connecting member are connected to the slide rail of the support rod from top to bottom; the servo motor is fixed on the first connecting member, the line laser is fixed on the coupling of the servo motor, and the servo motor is rotated by driving the line laser through the coupling; the first and second cameras are disposed on the secondconnection member and are located on both sides of the line laser with the line laser as an axis symmetry. The light is provided by the new line laser, the line laser can be rotated by driving the servo motor, the first and the second cameras are respectively located on both sides of the line laser, forming a binocular vision scanning structure, and the angle of the camera and the line laser can be adjusted by connecting member, which has a wider shooting range than the monocular visual scanning structure, and solves the situation where the surface of the monocular structured light is partially blocked.

Description

technical field [0001] The present invention mainly relates to the technical field of visual three-dimensional image construction, and in particular to a crosshair structured light binocular vision scanning device. Background technique [0002] With the rapid development of my country's processing industry and manufacturing industry and the continuous progress of modern detection technology, in the field of industrial measurement, the three-dimensional measurement technology of parts with complex surface topography has gradually become the focus of research. The line-structured light 3D measurement technology based on the principle of laser triangulation has the characteristics of high precision, easy expansion, and strong robustness, and has become the most widely used and most promising technology in non-contact 3D measurement. When the traditional single-camera linear structured light 3D measurement is faced with a more complex workpiece to be measured, the surface is par...
