Aiming at the situation that it is difficult for field engineers to develop robot vision program using machine vision system based on PC platform or embedded module,the relationship between robot and built-in visual recognition software was studied.Taking the integrated built-in visual recognition function software of FANUC robot as the research object,the physical connection between industrial camera and robot was introduced.Meanwhile,the principle and process of camera calibration were analyzed.Taking 2D shape and bar code workpieces as example,the processing process of visual recognition program,the key instructions of robot visual program and the flow of handling program were introduced in detail.By mixing and placing multiple models,the built-in vision system can accurately identified,the robot could make accurate sorting and carrying.The integrated built-in machine vision system of robot has simple hardware connection,abundant recognition tools,convenient application,as well as convenient interaction between robot program and visual data.Based on this,it has expanded the application scope of robot technology.Integrated built-in visual recognition function of robotis the development trend of automation field and machine vision system.
