The embodiment of the present invention provides a vehicle image retrieval method and device, the method includes: obtaining the image of the target vehicle to be retrieved; comparing the image of the target vehicle with the snapshot images saved at each road checkpoint to obtain multiple possible Contains the candidate snapshot images of the target vehicle, and the similarity between each candidate snapshot image and the picture of the target vehicle; according to the road network information, determine the geographic area where the target vehicle appears most frequently as the location trend area corresponding to the target vehicle; according to the preset In this way, the similarity of the candidate snapshot images taken at road checkpoints located in the location trend area is increased; according to the adjusted similarity, the retrieval result image is determined from the candidate snapshot images. By applying the embodiment of the present invention, according to the location trend area corresponding to the target vehicle, the similarity between the snapshot images stored at each road checkpoint and located in the location trend area and the target vehicle picture can be increased, so as to improve the accuracy of retrieving the target vehicle picture .
Description
technical field [0001] The invention relates to the field of image retrieval, in particular to a vehicle image retrieval method and device. Background technique [0002] At present, image retrieval technology has been applied in various fields. For example, in the field of intelligent transportation, image retrieval technology can be applied to investigate and deal with vehicles with license plates and vehicles with covered license plates. [0003] Specifically, firstly, obtain the picture of the target vehicle to be retrieved; then, compare the picture of the target vehicle with the captured images pre-saved at each road checkpoint, and calculate the similarity between the captured image and the picture of the target vehicle , wherein, the snapshot image is stored in the passing record information of each road checkpoint; next, calculate and obtain the snapshot image with higher similarity in the passing record information, and determine it as the retrieval result image co...
