Abstract

The invention discloses a vehicle speed measurement system based on intelligent video analysis, which comprises a contact table, a server side and a processing table, the contact table, the server side and the processing table are communicated through an Ethernet network, the contact table comprises a video acquisition front end and an image sorting front end, the video acquisition front end comprises a fixed video and a vehicle-mounted video, and the image sorting front end comprises an image sorting front end. The image sorting front end comprises a screening function block and a sorting function block. According to the invention, the image sorting front end screens and sorts the acquired video data, so as to ensure the credibility of pictures and image information as analysis objects; analyzing the selected picture by using a picture velocimeter, analyzing the selected image by using the image velocimeter so as to carry out second speed measurement calculation on the target vehicle, and carrying out comparative analysis on two speed results; by comparing the speed results obtained through calculation in the two modes and conducting dynamic modeling on the results, the vehicle driving condition can be analyzed more clearly in dynamic simulation.

Description

technical field [0001] The invention relates to the technical field of vehicle speed measurement, in particular to a vehicle speed measurement system based on intelligent video analysis. Background technique [0002] With the high-speed development of the economy, the number of vehicles is increasing day by day, which also promotes the rapid development of the transportation industry. At present, for the healthy development of the transportation industry, it is necessary to strengthen the monitoring and control of various vehicles, especially in high-speed driving sections, to ensure driving safety. Under the existing conditions, vehicle speed measurement is mainly completed by radar, but the existing license plate recognition function is mainly completed by video equipment, because the daily workload is huge, and the purchase of the whole set of equipment is huge, resulting in high cost of vehicle speed measurement system and maintenance work. large. [0003] Traditional ...
