Abstract
The application relates to the technical field of vehicle speed identification methods, and discloses a fuzzy image frame analysis vehicle speed identification method based on field reproduction, wherein, according to the differences of a camera, a field environment and road conditions, a field reproduction positioning measurement method in the fuzzy image vehicle speed identification method is divided into a direct measurement method and an indirect measurement method. Through the use of the method, the limitations and deficiencies of target vehicle calibration distance selection in the fuzzy video image for vehicle driving speed identification are overcome, the problems of identification failure and inaccuracy are solved, most of the video image identification materials which cannot be identified by using the traditional method regain the use value, the problems caused by the defects of the identification materials are solved, the requirements for the identification materials are reduced, the problems of fruitless vehicle speed identification and inaccurate vehicle speed identification results are solved, the scientificity and accuracy of the identification opinions are improved, and strong evidence support is provided for the traffic police department for accident handling.
