摘要
Abstract
On the basis of the comparison of the traditional moving vehicle real⁃time detection methods,a new G⁃C double difference method is proposed. The edge detection of a certain current frame and background frame in video stream is conducted, and then the results are subtracted from the two frames to get the gradient difference. After that the ″or″ operation for the differ⁃ence result and background color difference result is performed to greatly improve the accuracy of the vehicle judgment. This algo⁃rithm can accurately detect the existing moving vehicle on the road and effectively eliminate the effect of vehicle shadow,which provides a strong guarantee for the real⁃time detection of the following vehicle moving velocity. Based on the results of moving ve⁃hicle detection,the programming realization was conducted in VC environment to automatically detect the real⁃time speed of the moving vehicle. The test results show that the effect of the algorithm is perfect.关键词
