摘　　要：机器视觉技术对激光机器人加工过程检测与控制具有主要作用。基于CCD/CMOS光电视觉技术,开展了激光再制造机器人零件三维几何形貌重建、激光熔池温度场、同轴送粉粉末流浓度场等3种机器视觉系统研究。3D形貌机器视觉系统：扫描宽度200 mm,扫描速度10-50 mm/s,最大误差小于1 mm。温度场机器视觉系统：测温范围700℃-2400℃,精度50℃。粉末流场机器视觉系统：粉末流量检测范围1-100 g/min。3种系统均可进行实时检测,且体积小,能方便地与机器人安装、耦合。Machine vision plays an important role in measuring and controlling for laser robot processing.Based on CCD/CMOS,three kinds of machine vision systems for laser remanufacturing robot are developed to reconstruct of 3D-CAD part,temperature field and powder stream field.Their parameters are as follows： scanning width is 200 mm,scanning speed is 10~50 mm/s,deviation is less than 1 mm in 3D-CAD part;measuring temperature regions are 700 ℃~2400 ℃,deviation is less than 50 ℃;measuring powder stream rate regions are 1~100 g/min.They all can realize a real time and online testing and are available in laser remanufacturing robot processing.
