| Abstract: |
| Aiming at the fast measurement problem of high precision parabolic antenna, a new 3D measurement method based on the robot was proposed. The working path could be planned and the off-line program for the trajectory could be made by the software named robotmaster, and then the 3D scanning automatic measurement program of antenna could be generated. After debugging the robot trajectory on the scene, the automatic scanning of the antenna surface could be measured by the robot with a 3D optical scanner at its end. Comparing the actual data with the theoretical model, the size and shape deviation of the parabolic antenna could be got by the software named ATOS Professional. By comparing the results obtained from CMM, it has been proven that the reliability and efficiency were highly increased and the measuring range was enlarged to a certain extent by the new measurement system integrating the 3D scanner and the robot. It shows that the new measurement system has great application value and it provides bases for the manufacturing efficiency and precision of composite parabolic antenna. |
