3D detection and reconstruction of worn parts for flexible remanufacture

In recent years, flexible remanufacture has become new research focus because of the requirement of rapid repair and reuse worn parts. 3D modeling of the worn parts is the precondition of flexible remanufacturing system. According to the random position and the various forms of worn parts, 3D detection and reconstruction are necessary. First, this paper establishes a 3D detection and reconstruction system based on linear laser. The mathematic model, work principle and composition of this system are introduced, and then, according to the analysis of this system, a two steps rapid calibration algorithm is proposed. When the system parameters are calibrated, it is able to acquire 3D information on surface of worn parts in the form of scattered point data clouds. Finally, take a coupler kunckles as the worn part, 3D detection and reconstruction verifying experiment is carried out.
