Based On The CCD Image Processing Vehicle Active Safety Systems

Safety is the eternal theme of the vehicle Driving, as the rapid development of freeway,traffic accidents were rising trend, safety is widely concerning by people. Based on the CCD image processing vehicle active safety systems can detect obstacle to find out the potential danger to vehicle driving, and make the vehicle brake away from it, the large numbers of the movement of objects appeared in our vision in the vehicles driving, therefore, moving target detection and tracking method is of great significanceIn this paper, image processing integrated analysis and comparison of the histogram equalization, smoothing, Fourier transform, wavelet, wavelet packet filtering in image enhancement; A mathematical morphology is newly used image processing and mode identifying in the new neighborhood, this paper comprehensively analyze the characteristics of the image processing of mathematical morphology in the binary image.Based on the Edge Detection partly as a result of complex imaging conditions, the noise in the image, and a different edge detection operator can be applied not the same of the field,and so on. this paper use the differential treatment method by combined digital images and mathematical morphology:using median filter template, the median filtering, image noise was removed and the image edge to protect good, and then based on the corrosion on the verge of computing algorithm to extract image corrupting computing, on the edge of the gray image has been strengthened, reuse difference method, and thus gained the edge of the image. Image Edge Extraction by the loss of small details, image quality is good,so-details from the edge, the edge continuity, and edge detection can be more conducive to overcome common Sobel operator, Laplace operator, LOG operator, Prewitt operator, Canny operator, and other existing deficiencies, such as euge after filtering in the direction information is lost or wide or on the borders general, and other noise-sensitive.In the paper, the vehicle motion image mode identifying adopt the template matching method, by traffic characteristics of moving target; system through simulation, the results confirmed the effectiveness of its methods.Vehicles travelling security mechanism and control algorithm based on the basis of the image acquisition, processing, recognition in the vehicle driving, the preparation of the corresponding control procedures on the auto ABS ECU for the corresponding improve design, implemented operation of the vehicle security auxiliary warning function.CCD image processing based on the vehicle active safety system through interactive or control of the ABS to achieve the purpose of active safety.
