Realization of DXF File Analysis and Vectorgraph Overlay Based on Embedded Linux Platform

This paper analyzes the structural differences of various elements in the DXF file, and uses the pure C++ library dxflib to develop a DXF file analysis and drawing program with Qt Creator. The program supports translation, rotation and zoom operations of the DXF vector graphics. Integrating the program into our embedded Linux camera can realize positioning and preliminary shape judging of the workpiece, which achieved good results.
