Abstract: The environment of the runway of intelligent car is complicated,and the traditional otsu thresholed segmentation method can not achieve mecise segmentation of the runway image.On the basis of the analysis on the birnarization of the tradtional otsu method,the block otsu binarization for intelligent runway image processing is proposed.This algorithm can achieve fast and precise segmentation of runway threshold and effective runway recognition,effectively copmplete path identification.

Key words: intelligent car, image acquisition, image processing, otsu method
