Design of a 3D Reconstruction System with Automatic Correction Function

Abstract

In view of the problem that it is difficult to prepare for measuring the external dimensions of materials after heat treatment such as extrusion, stretching and straightening in factories, which is not conducive to further processing of materials in the later period, this paper designs a 3D reconstruction system which can quickly scan and reconstruct materials, obtain the deformation of materials, and measure the dimensions such as edge distance and surface flatness of materials. It can not only realize the continuous reconstruction of three-dimensional system of single material and the automatic reconstruction of starting and stopping root material by using the presence or absence of monitoring sensor of material in on-line non-stop state; At the same time, the basic size, deformation size and smoothness parameters of the reconstructed model are calculated In order to calibrate the center position deviation of materials with different sizes, reduce the influence of position information on the dimensional accuracy of material reconstruction, and increase the automatic correction function of center position. This design can supervise and feedback the processing effect of materials processing, and provide effective data reference for the further processing of materials and the reasonable combination of processing procedures. This design can improve the automation degree of processing and the quality of processed materials.
