Abstract：The development of driver assistant system based on the On-board machine vision is helpful to ensure driving secureity because more than 80% driver\\\\\\\��s information is obtained by vision. On the basis of discussing the operation process of driving vehicle,this paper divided the machine vision of driver assistant system into external information machine vision and internal information machine vision technology according to the scope of information acquisition, including: driver’s vision enhancement, driver’s vision improvement, understanding of path environment , line of sight tracking and driving weary monitoring. The domestic and foreign researching situation of this field at present was also summarized . At last, current research insufficiency of the machine vision technology in driver assistant system was analyzed. The conclusion was that some research should be taken into deeper investigation ,such as driver vision enhancement method in low visibility, information fusion of path environment understanding as well as driving weary examination.
