Embodiment Construction
[0076] Such as figure 1 As shown, the video-based multi-vehicle traffic information detection method of the present invention specifically includes the following steps:
[0077] Step 1: Traffic video collection. Capture traffic video with cameras mounted above the road to capture oncoming traffic flow. Each frame of image output by the traffic video stream is an RGB color image, and the image acquisition frame rate is at least 29 frames per second.
[0078] Step 2: Parameter setting. see figure 2 , to set the size and position of the virtual detection coil. The set virtual detection coil is rectangular, and its width is equal to the width of the lane where it is located. One lane virtual detection coil is placed in each lane, and a cross-lane virtual detection coil is placed between every two adjacent lanes to avoid vehicle leakage. For inspection, the placement of the virtual detection coil is perpendicular to the direction of traffic flow, and it is placed in a positio...
