Problems solved by technology
Since the capture device captures the image of the vehicle, the capture position is unstable. Therefore, during the period from t1 to t2, the actual driving distance of the vehicle is different from s, which will cause the calculated driving speed to be inaccurate.

The embodiment of the invention provides a vehicle running speed detection method, device and system and electronic equipment. The method comprises the steps of: acquiring a first snapshot image of atarget vehicle at a speed measurement starting point and a second snapshot image of the target vehicle at a speed measurement terminal point; performing image recognition on the first snapshot image and the second snapshot image, and determining a first distance between the target vehicle and a pre-calibrated speed measurement starting line and a second distance between the target vehicle and a pre-calibrated speed measurement ending line; determining the actual driving distance of the target vehicle based on the first distance, the second distance and the distance between the speed measurement starting line and the speed measurement ending line; and determining the driving speed of the target vehicle according to the actual driving distance and the driving time. Based on the first distance, the second distance and the distance between the speed measurement starting line and the speed measurement ending line, the actual driving distance of the target vehicle can be accurately determined, and the accuracy of the detected vehicle driving speed is greatly improved.
Description
technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a detection method, device, system and electronic equipment for vehicle speed. Background technique [0002] Checkpoint is the abbreviation of road traffic security checkpoint monitoring system. It refers to a road traffic on-site monitoring system that relies on specific places on the road to photograph, record and process all vehicles passing through the checkpoint. Wherein, the specific place may be a toll booth, a traffic or public security checkpoint, and the like. [0003] Interval speed measurement is a checkpoint-based on-site monitoring method for road traffic. Specifically, two adjacent checkpoints are arranged on the same road section, and the average driving time of the vehicle on the road section is calculated based on the distance between the front and rear two checkpoints and the time it takes for the vehicle to pass through the front and back t...
