Abstract

The invention provides a vehicle recognition method based on image detection. The vehicle recognition method includes the steps that a vehicle image of a vehicle is obtained by means of a monitoring device, feature filtering processing and normalization processing can be carried out on the vehicle image, and accordingly the vehicle image undergoing normalization processing can be obtained; a feature vector of the vehicle image obtained after normalization processing is obtained; the feature vector of the vehicle image undergoing normalization processing is compared with a corresponding feature vector of vehicle samples in a database, and accordingly the vehicle sample most similar to the vehicle image undergoing normalization processing in the database is obtained; the type of the obtained vehicle sample in the database serves as the type of the vehicle. According to the vehicle recognition method based on image detection, by means of normalization processing and comparison processing, the type of the vehicle can be quickly, efficiently and accurately recognized; the technical problems that an existing vehicle recognition method is low in recognition efficiency and poor in recognition accuracy are solved.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a vehicle identification method based on image detection. Background technique [0002] In order to achieve traffic management, such as traffic flow investigation, traffic violation evidence collection, or fully automatic toll collection in expressways and parking lots, the technology of classifying and identifying vehicles has become more and more important. [0003] Vehicle detection and recognition technology based on video images is a non-contact passive detection technology. It takes video images as the main analysis object, uses video cameras to extract traffic images from video streams, and uses computers to imitate human visual functions, extracts effective information by analyzing and processing images, and performs vehicle detection and detection based on the effective information. Model identification. [0004] Among the existing vehicle recognition methods based on i...
