The effect of outer scale of atomospheric turbulence on tracking precision of tilted tracking system is studied by considering G-tilt power spectrum and the residual variance of tilted tracking system.

According to the tilt tracking circle of adaptive optical system,a real-time tracking processor is built based on PCI bus,and the core processor is DSP and FPGA.

Study of welded seaming tracking system of 3D vision based on structure light;

Research on ultrasonic wave sensor welding-seam tracking system;

The PLC design for single axis sun-tracking system;

frame frequency transformation technique, nonuniformity correction technique, recognition and tracking technique, etc) of improving the performance of infrared imaging tracking systems on the terminal guidance at present are proposed in this paper.
