Embodiment Construction

[0018] Aiming at the problems existing in the prior art, the present invention proposes a vehicle image retrieval scheme applied to traffic checkpoints, which can improve the accuracy of retrieval results.

[0019] In order to make the technical solution of the present invention more clear and understandable, the solution of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0020] figure 1 It is a flow chart of an embodiment of the vehicle image retrieval method applied to traffic checkpoints in the present invention. like figure 1 As shown, the following steps 11-12 are included.

[0021] Step 11: Determine the reference image of the checkpoint vehicle and the retrieval image of each checkpoint vehicle as the retrieval object.

[0022] For example, if the user needs to inquire about the whereabouts of a certain illegal vehicle, the user can provide a checkpoint vehicle reference image about the vehic...

Abstract

The invention discloses a vehicle image retrieval method and a vehicle image retrieval device for a traffic block port. The vehicle image retrieval method comprises the following steps: determining block port vehicle reference images and various block port vehicle retrieval images as retrieval objects; acquiring textural feature codes of the block port vehicle reference images; aiming to the block port vehicle retrieval images, respectively acquiring the textural feature codes of the block port vehicle reference images, and calculating the similarity between the textural feature codes of the block port vehicle retrieval image and the textural feature codes of the block port vehicle reference image; sorting the block port vehicle retrieval images according to the similarity sequence from high to low, and displaying to a user. With application of the scheme, the accuracy of the retrieval result can be improved.

Description

technical field [0001] The invention relates to image processing technology, in particular to a vehicle image retrieval method and device applied to traffic checkpoints. Background technique [0002] In the prior art, at some important traffic checkpoints, such as expressway toll gates, public security checkpoints, etc., the installed camera device is usually used to take pictures of each checkpoint vehicle passing by, and the captured The bayonet vehicle image is saved to the database for subsequent retrieval and viewing. [0003] In the prior art, the color, model, shooting location and shooting time of the bayonet vehicle are usually used for bayonet vehicle image retrieval, that is, the bayonet vehicle image matching the text description is searched in the database according to the text information input by the user, such as A small white truck passing by the toll gate of the × expressway on ×year×month×day. [0004] However, the above method will have certain problems...
