Target information acquisition method and device

Abstract

The invention provides a method and device for acquiring target information. The method includes: the image acquisition device acquires a passing picture of a passing vehicle, identifies and locates a target object in the passing picture, and obtains position information of the target object in the passing picture; the image acquisition device writes the position information into the passing picture , obtain the vehicle picture including the target object position information, and send the vehicle picture to the server for storage; the server responds to the target information acquisition operation, and extracts the target object position information from the stored vehicle picture; the server according to the obtained target object position information The vehicle picture is matted to obtain the corresponding target object picture, and the corresponding target information is obtained based on the target object picture. The method is easy to operate, can save storage resources of the server, improves picture redundancy, and can directly acquire target object pictures from vehicle pictures to obtain corresponding target information.

Description

Technical field [0001] The present invention relates to the field of video surveillance technology, in particular, to a target information acquisition method and apparatus. Background [0002] With the continuous development of science and technology, the application of video surveillance technology in various industries has become more and more extensive, of which the application of video surveillance technology in traffic management systems is particularly prominent. As far as the existing traffic management system is concerned, the image acquisition device (e.g., network camera) needs to separately extract the object picture of the target object (e.g., license plate, body or logo, etc.) from the traffic picture after taking the traffic picture of the passing vehicle, and upload the traffic picture and the object picture as a vehicle traffic record to the video management server for storage, so that the video management server can query the vehicle based on the traffic picture...

AI Technical Summary

Problems solved by technology

Among them, the object picture is a part of the passing picture, and the image acquisition device uploads the two pictures to the video management server for storage, which will cause the video management server to allocate storage space to store the object picture separately, resulting in redundant pictures and waste of storage resources

At the same time, the video management server needs to spend a lot of computing resources to call the corresponding target object picture according to different storage paths to obtain the target information of the picture when performing motor vehicle query. The whole information acquisition process is extremely complicated.
