Abstract

With the development of sensor technology and the increasing demand of industrial upgrading, high intelligence and high-precision processing and manufacturing is the development trend of the future automation industry. As the eye of industry, sensor is the core part of intelligent industrial system. Line-structured light sensor is widely used in automatic manufacturing because of its non-contact, high-robust, and high-precision characteristics. This paper analyzes the latest application and research of line-structured light sensing technology in the industrial application of workpiece object detection and positioning, geometric profile measurement, three-dimensional reconstruction. It is found that line-structured light can provide more convenient advantages for high-precision measurement in automatic production line with its non-contact advantage. Through the feature extraction and reconstruction of the surface profile, the accurate estimation of the three-dimensional shape and coordinates of the workpiece can be realized, which lays the theoretical foundation and practical basis for further realizing the automatic manufacturing.
