가공 시작점 인식을 위한 다중 스케닝 비전센서 시스템 개발
초록
The purpose of this study is to develop a system that can accurately extract the machining start point based on the developed laser vision sensor system in the manufacturing system for carbon fiber reinforced plastic (CFRP). The developed sensor system comprised a multi-line laser scanning module, camera-based image acquisition module and specially designed image processing algorithm. The multi-line scanning module created several laser lines on a hole located on the CFRP, and the captured images were processed to extract the coordinate information of the hole on CFRP. Finally, The machining start point was extracted using the n-point circle center extraction method.
To verify the reliability of the developed sensor system, numerous experiments were tested and analyzed to increase the accuracy through the actual field system.
