[0064] The present invention will be further described in detail below in conjunction with the drawings.
[0065] The method for counting traffic flow based on the detection of moving vehicles of the present invention has a specific operation process such as figure 1 As shown, the following steps S1-S4 are included.
[0066] S1 obtains the video stream image, and preprocesses the video stream image using a multi-scale morphological gradient operator;.
[0067] In order to reduce the amount of calculation and save the calculation time, only the image of the detection area is preprocessed to better meet the requirements of real-time processing.
[0068] The present invention adopts a gradient filter for preprocessing, which can suppress the influence of brightness, shadow changes and noise, and specifically adopts multi-scale morphology for preprocessing. The multi-scale morphological gradient operator uses an average operation method to make the operator Obtain stronger anti-noise abi...
