基于双目电荷耦合器件的三维形貌检测装置研制.

In the experimental teaching of sensor technology course, visual sensor is used to carry out the teaching requirements of non-contact shape detection, and a 3-dimensional shape detection device based on binocular charge couple device( CCD) is designed. Based on the functional analysis of the experimental teaching device, the overall scheme of binocular CCD vision measurement including horizontal and vertical directions is completed. The horizontal direction is reconstructed by multiple image sequences in three dimensions, and the vertical direction passes through different height sections of the measured object. The hardware design is carried out, mainly including image acquisition, mechanical movement and bracket design, and the reliability analysis of the mechanical structure is carried out.According to the working scheme of the device, this paper makes a corresponding theoretical analysis on the two 3-dimensional reconstruction methods so as to give a theoretical basis for the software implementation. The software design is carried out in the Windows environment. The multi-image 3-dimensional reconstruction is performed by integrating VisualSFM, PMSV and Meshlab. At the same time, according to the overall scheme, the corresponding image acquisition program is designed. Finally, the overall 3-dimensional shape detection system is completed, the experimental test is carried out, and the experimental process and result analysis are given in this paper.
