ABSTRACT
Correct recognition of lane information is the foundation for proper vehicle control, therefore what kind of sensor we choose to detect lane information will determine what kind of control method could be used. In this paper we have an estimation of the pre-detecting ability of using photoelectric sensors as the lane-detecting sensor of the intelligent vehicle, as well as a discussion of what parameters will affect the pre-detecting ability of photoelectric sensors. First we make a study on factors which influence photoelectric detecting and to what extent, and basing on this study we put forward proper methods to improve current photoelectric detecting module. Besides, we optimize the parameters and installation position of the photoelectric module so as to achieve best detecting effect. Finally, we compare both advantages and disadvantages of photoelectric sensors with those of CMOS camera, with a description of the prospect of both sensors.
