Abstract

Arc segmentation is essential for high-level engineering drawing understanding and is very difficult due to its high order geometry form and the mixtures of other geometry lines. We present an arc segmentation method that is implemented in the current version of the machine drawing understanding system. The method follows closely the perpendicular bisector tracing algorithm we developed before. Some important variations are being explored to improve the efficiency, lower the number of false arc detections and improve the accuracy of the detected arcs. Experimental results are presented and discussed.
