Abstract

This paper introduces the composition of the autocollimator tracking system, and analyses in detail the image processing part and servo tracking part of the system. The image processing part uses TMS320DM642 DSP to complete the image acquisition and image display. Using RS232 serial ports to transmit each frame offset of target to the servo tracking part. According to the offset information, the servo tracking part makes use of TMS320F2812 DSP to complete real-time tracking. Autocollimator tracking system uses two rhombic prisms to ensure real-time transmission of optical path. Experiments show that the autocollimator tracking system can achieve 1HZ real-time tracking and fully meets the project needs.
