An Algorithm about Dimensions Recognition Based on Graphic Features
Lin Da-jun · 2012
According to the picking mode of dimensions,roughness,and tolerance form and position of engineering drawings,DXF(Drawing Exchange Format)code information is obtained,then,critical information of dimensions is excavated.The relationship between graphics structure and dimensions is established,a recognition algorithm for dimensions is proposed and implemented based on the features of graphic.Dimensional chains are stratified,tracked and recognized by analyzing and extracting various types of dimensional information.Comprehensive,recognition and correction for topic multi-solutions is realized with the connection of views and expansion from points to line based on alignment principle.
