The invention relates to a method for rapidly detecting vehicles based on frame difference and light streams. The method comprises the following steps: confirming an interesting area of a detected vehicle; acquiring a frame difference image of the interesting area of a next frame of image after acquiring different frames of images, and processing, thereby obtaining binaryzation frame difference images of different frames of images; confirming suspected target areas in the binaryzation frame difference images; determining the suspected target areas of which the light stream convergence is greater than a threshold which is preset by the system, as image areas of corresponding vehicles; performing overlap ratio comparison on different frames of the images with the vehicle image area of a next frame of image, and confirming initial and ending image areas of the vehicles. By adopting the method for rapidly detecting vehicles based on frame difference and light streams, two algorithms of frame difference and light stream are combined and further optimized, so that the situation that vehicles can be wrongly detected in rainy days or vehicle lighting and tree shade influence cannot be avoided in similar algorithms is avoided, the calculation burden of the algorithm is relatively small, the realization property is very high, vehicles can be rapidly detected, and the method is relatively wide in application range.
