A survey on three-dimensional modeling based on line structured light scanner

Three-dimensional modeling technology is a key technology in many areas of research. As a non-contact three-dimensional modeling device, line structured light scanner has the advantages of non-destructive, high precision, real-time, good anti-interference ability. This paper introduces the measuring principle of line structured light scanner and the system configuration of three-dimensional scanning system. In this paper, the key technologies in three-dimensional modeling system based on line structured light scanner are presented, including calibration of three-dimensional modeling system, strip centers extraction, structured light scanner view planning, point cloud data processing and three-dimensional reconstruction. Last, a review of the development process of structured light based three- dimensional modeling technology is presented.
