Visual Measurement for On-Orbit Reflector Assembly

摘要

In Earth orbit, a space telescope is free from any absorption or disturbances from the Earth's atmosphere. Therefore, a large space telescope is planned for the future. We discuss the assembly of a large telescope reflector performed by a robot arm. For the assembly work, positioning of the arm using visual servo control to colored markers is proposed. A ground test-bed is used to test the characteristics of the new image processing method for colored markers. The results of the tests are also given.
