Research and Application of Key Techniques of Surface Displacement Analysis System Based on Imaging
摘要
Abstract
Non-contact surface displacement measurement, as a nondestructive measurement technology, has been widely used in many engineering fields. For concrete'' s stress and strain testing and river channel'' s instantaneous flow field measurement, we developed non-contact surface displacement measurement systems based on digital speckle correlation method and particle image velocimetry. Some key issues in the developed systems are discussed and the corresponding treatments are given. The experimental result proves the effectiveness of the proposed method. Nevertheless, there are still some technical defectives to be furthered researched, including 3-D velocimetry of multi-perspective CCD camera, multi-purpose line tracing, and highly-precise fusion of measurement data of differ-ent scenes.关键词
