Abstract

Embodiments of the present invention provide a method and device for image search based on bayonet data, including: acquiring the body area in the target vehicle image, and then extracting feature information of the target vehicle image from the body area, the feature information including the target vehicle image The feature points and the scale, main direction and relative position of the feature points. Then query the feature points of the sample image stored in the feature database and the scale, main direction and relative position of the feature points of the sample image according to the feature information of the target vehicle image, and determine the image similar to the target vehicle image. In the embodiment of the present invention, according to the multiple feature points of the extracted target vehicle image and the related information of the feature points, similar images are found from the bayonet database. , can still find similar images from the bayonet database, which improves the accuracy of finding similar vehicle images from the bayonet database.

Description

technical field [0001] Embodiments of the present invention relate to the field of intelligent transportation, and in particular to a method and device for searching images by image based on checkpoint data. Background technique [0002] With the rapid development and progress of cities, urban safety has also received more and more attention. When carrying out video investigation, search for decked vehicles, and search for suspect vehicles, it is necessary to find out the pictures of the same vehicle from the bayonet database according to the pictures of the target vehicle. The traditional bayonet vehicle retrieval system can only perform part of conditional query or combined conditional query based on license plate information, vehicle color, model, brand year and model information. However, there are a large number of existing vehicles, and there is a high probability of duplication of vehicle color, model, and brand age information. When the license plate information is ...
