However, the existing algorithm often loses the target in the case of multi-camera cross-camera connections and traffic participants with large occlusion overlaps, resulting in changes in the traffic participant’s ID and other information, which brings a large number of subsequent target counts.

The embodiment of the invention discloses a traffic flow statistical method and device based on roadside perception, and the method comprises the steps: 1, dividing an intersection in a picture shot by a roadside camera into an inner region and an outer region, the inner region being a counting region, and the outer region being a non-counting region; 2, detecting traffic participants in the video picture, and outputting a traffic participant information set of the current video frame obtained by a detection model based on deep learning; 3, tracking traffic participants in the video picture to obtain a tracking information set of the (f + 1) th frame; step 4, removing traffic participants which do not meet requirements; step 5, analyzing the information of each frame of image, accumulating the journeys of all traffic participants of one category in unit time, and if the sum is greater than the Euclidean distance of the counting area, adding one to the counter of one category, and if the sum is greater than the Euclidean distance of the counting area, adding one to the counter of one category; and step 6, outputting the value of each type of counter to obtain a traffic flow statistical result.
Description
technical field [0001] The present invention relates to the technical field of intelligent traffic, in particular to a traffic flow statistics method and device based on roadside perception. Background technique [0002] Roadside surveillance data exists in various scenarios of smart transportation, and massive amounts of roadside surveillance video data are generated on the ever-changing traffic roads every day. Road traffic flow information plays an important role in intelligent guidance and scheduling of traffic participants in smart transportation. [0003] The traditional traffic flow statistics need to manually check the real-time conditions of the road, and people's energy is limited, and they often make misjudgments in the face of the continuous traffic flow. Among the existing traffic flow statistics technology, one is the counting method based on lane lines. This method needs to lay electronic coils inside the road. The cost of road surface renovation and upgradin...
