Abstract
The flatness of large deployable antenna needs to be measured several times during the deployment test, the theodolite measurement accuracy was low and the speed was slow, and the laser radar measurement range was limited. By building a flatness rapid measurement system for large deployable antenna, using autonomous navigation mobile technology to plan measuring path, and using digital photogrammetry technology to detect the flatness of antenna. It can realize rapid and automatic measurement for flatness of large antenna. The test results show that the accuracy of digital photogrammetry camera and laser tracker is no more than 0.05mm; the measurement accuracy of the flatness rapid measurement system shall not be more than 0.034mm away from the accuracy of laser radar, it can meet the requirements of flatness rapid measurement of large deployable antenna. This method can improve the efficiency and automation level of flatness measurement of large deployable antenna, and it lays a foundation for the plane measurement of large deployable antenna with larger size and more complex structure.
