Abstract:Vehicle logo location is one of the key technologies of vehicle logo recognition system. However, because of the different texture and variety of radiators in the background, it is difficult to locate the vehicle logo. Therefore, a vehicle logo location method based on background texture is proposed. Firstly, the method locates the vehicle logo roughly according to prior knowledge, then divides the background of the vehicle logo into three categories according to its characteristics on horizontal and vertical projections, and then uses Sobel operator to ablate the background of different types of radiators. In order to better remove the influence of radiator background on the location of the vehicle logo, a neighborhood binarization method is introduced, which combines projection-based method. The denoising method further deals with the noise points, so as to realize the accurate positioning of the vehicle logo. This method is suitable for different types of vehicle logo background conditions. The experiment results show that the proposed algorithm has higher accuracy and applicability by positioning 1000 images, and the overall positioning accuracy can reach 97.10%.
