基于双目视觉的电力物资三维模型构建及检测技术研究OA

Taking the hardware of power transmission lines as the research subject,firstly,it adopts digital 3D laser scanning tech-nology to analyze the principle of 3D laser scanning and the sources of errors,and collects the 3D point cloud data on the surface of the hardware.With the help of HyperScan software,it completes reverse modeling and establishes a three-dimensional data model of the hardware,providing a fast means for the digital preservation of power material samples.Secondly,by applying the Polyworks detec-tion software,it analyzes the appearance features of the hardware and establishes a model reference alignment method to obtain the all-round deviation distribution between the 3D model and the CAD design drawing model.Finally,it evaluates the measurement uncer-tainty of the three-dimensional reverse modeling size inspection technology and the digital display electronic vernier caliper measurement method,providing a scientific evaluation method for the three-dimensional reverse modeling detection technology.
