Abstract: With radiometry as a standard,cooperative targets opto-power models and equation of CCD camera detection were established.The restrictive relationship between cooperative targets opto-power and CCD camera parameters was obtained.Imaging definition which CCD camera works in limited distance was solved by using hyperfocal distance.Telecentric optical system was employed in order to solve the precision of measuring systems.The relationship of pixel number CCD camera detect and operating distance was analyzed.It is studied what influences CCD camera when the sun radiates FOV of CCD camera and mechanic part of docking reflects from the sun.
