[0064] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0065] A kind of traffic flow statistical method based on moving vehicle detection of the present invention, its specific operation process is as follows figure 1 As shown, the following steps S1-S4 are included.
[0066] S1 acquires a video stream image, and uses a multi-scale morphological gradient operator to preprocess the video stream image;
[0067] In order to reduce the amount of computation and save computation time, only the images in the detection area are preprocessed to better meet the requirements of real-time processing.
[0068] The present invention uses a gradient filter for preprocessing, which can suppress the influence of brightness, shadow changes, and noise. Specifically, multi-scale morphology is used for preprocessing, and the multi-scale morphological gradient operator uses the average operation method to make the operator Get stro...
