Scanning imaging system based on stripe type laser sensor and robot

A system solutions was proposed that utilized the platform composed of stripe type laser sensor and industrial robot for scanning and detecting workpiece, imaging for its contour as well. Stripe type laser sensor obtained the three-dimensional point cloud data of the workpiece contour by scanning in movable way. Then combined with the specific algorithm, point cloud data was dealt with through denoising, interpolation processing, which made the point cloud data reflect the objective morphology of artifacts more truly. Finally according to the information of point cloud data, binary images of the workpiece contour was generated. In the experiment, the precision of imaging can reach to 0.1 mm. Thereby, imaging, detection and location for the workpiece are realized instead of traditional CCD camera in some special industrial occasions, solving the problem that traditional CCD is lack of anti-interference ability.
