Embodiment Construction
[0017] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0018] figure 1 It is a flowchart of the method of the present invention, the method may further comprise the steps:
[0019] S1: using an infrared camera to perform infrared photography to obtain video image signals. The installation of the camera can be arranged on both sides of the road or above the road according to the actual spatial layout, so as to fully cover the curves of the mountainous roads.
[0020] S2: performing foreground detection by using an adaptive mixed Gaussian modeling method, the specific steps of the adaptive mixed Gaussian modeling method in the step S2 are as follows:
[0021] S21: Establish a mixed Gaussian background model to characterize the characteristics of each pixel in the image frame;
[0022] S22: adaptively update the background model, and calculate the foreground mask;
[0023] S23: Perform morphol...
