Practical Technologies Research of Line Structured Light Three-Dimensional Profile Measurement at Low-Cost

Abstract

In this paper, a new method for determining the integrity of the image element of the target was proposed based on the self-made low-cost line structured light three-dimensional measurement platform, and BP neural network was used to complete the calibration of line structured light camera system. At the same time, Gaussian model for the four direction were constructed , which speeds up the extraction speed for the laser stripe center based on the gray gravity method of skeleton, and the point cloud data is deal with the refinement, noise removing, smoothing and three-dimensional reconstruction, which complete the task of product three-dimensional contour detection.
