摘　　要：在理论上分析了基于弥散斑的单基站定距方法,并利用远心光路改善弥散斑的测量。为了提高测距范围,在成像光学系统前加一望远光学系统,可以适当改变整个系统的焦距,改善系统的测距范围,从而可以实现单基站定距。The method of distance measurement based on defocused spots from mono-view is analyzed in theory, and the telecentric light path is used to improve the detection of defocused spots in the system. In order to enlarge detection ranges, a telescopic lens are used before the imaging lens, the system focal length will be changed. In this way, the detection ranges is improved and the distance measurements from mono-view can be achieved.
