Abstract: A frontal vehicle location and identification method based on the fractal box dimensionality(FBD) was proposed to help the auto-guided vehicle development. The horizontal edge informations of the located vehicle were obtained by the image difference and linear filtering. The search area of the FBD was reduced by the statistical method. The potential vehicle region was determined by calculation of the FBD and the location of the vehicle was achieved in this region. At the same time, a validation algorithm based on the symmetry measures was proposed to check the correctness of the vehicle location. The tests of the vehicle images under different environments and illuminations show that the proposed method is characterized by good robustness and reliability.

Key words: engineering of communications and transportation, vision, fractal box dimension, vehicle location and identification
