Design of Three-dimensional Scanning Measurement Experimental Platform Based on Industrial Robot
To support the talent training of new engineering majors,a set of 3D scanning measurement experimental platform is designed.The hardware system of the experimental platform mainly includes industrial robot,laser scanner and optical tracking system.The 3D interactive environment is created and the CAD model of the parts to be measured is imported on OpenCASCADE.The measurement points of the free-form surface are extracted according to the curvature characteristics of the free-form surface,the position and pose of the robot end at each measurement point are calculated by quaternion method.The robot scanning path is generated and collision detection is carried out in the simulation software RobotStudio.The robot executable file of scanning path is generated and loaded on the robot,then the scanning measurement with high efficiency and high precision is completed.The experimental platform can support the"Three-dimensional Intelligent Perception Technology"course under the intelligent perception engineering major.It is helpful for students to have a deep understanding of optical precision measurement,robot modeling and other related knowledge,and improve students'practical ability and innovation ability to solve complex detection problems.
