The wavelet packet has good time-frequency localization character and adaptive ability, and the aim is to achieve lower image noise and recover the original image in the field of image preprocessing applications. In order to realize the autonomous vehicles for road information and the accurate control of operation, the paper uses the method of the wavelet packet transform and the average filtering to preprocess the collected image data. Finally, through the method of binarization with the maximum variance select threshold, dynamic iterative threshold method, it can p this de ick up the black guide line. Compared with the traditional sign is accurate and complete to extract the black guide lines in the track. A large number of simulation experiment results show that the scheme design in the aspect of gathering information is accurate, simple and effective. In addition, this design has been well validated in the intelligent car platform.
