Abstract :
A calculation of exposure time based on the light measurement often refer to errors in the deepness space detection duo to darkness background of deepness space and over hundreds of kilometers between the camera and the target. However, the use of based on an auto-exposure statistic and compensation method overcome those defects that mentioned before. Consequently, average gray level in the object area could be successfully adjusted to the excellent gray scale. Scientifically speaking, the application of auto-exposure method has benefits to promote the impact of exposure unknown size or light target in the darkness background.
