Embodiment Construction

[0023] Such as figure 1 As shown, the software implementing the method of the present invention is loaded into the intelligent analysis and retrieval system, which is mainly applied to the transportation department to analyze historical video data or real-time video data. For historical data, the intelligent analysis and retrieval system analyzes the video stream and needs to be deployed The corresponding program, after specifying the physical medium where the video data is located, the system performs indexing and search operations on the video data, and analyzes relevant user demand information. For real-time data, the system can be in the middle layer of data transmission (software level) or The hardware transfers the video data (physical level) that needs to be analyzed to index the user's demand information and complete the search task.

[0024] The method for retrieving vehicle information in video images of the present invention includes the following steps:

Abstract

The invention relates to a method for searching vehicle information in a video image. The method comprises the steps of: decoding video data in the video image and separating data frame to form YUV data or RGB data; carrying out rough searching of vehicles on each frame of video image to obtain vehicle outline characteristics, color characteristics and number plate recognition results; determining moving tracks according to the changes of coordinates on the image; separating the integral time interval of each vehicle emerging in the current video flow from time; and building a vehicle information database comprising vehicle emerging time, time of each vehicle leaving the video frame, vehicle running direction, vehicle body type, vehicle body color, number plate color, number plate number and running path for querying and searching by users according to the vehicle geometrical characteristics, color characteristics, moving tracks and number plate recognition results in the integral time interval. By adopting the method provided by the invention, the efficient utilization rate of the data by the traffic department and traffic police department is greatly increased, detailed and reliable data is provided for subsequent systems and platforms, and the automation degree and data utilization rate are increased.

Description

Technical field [0001] The invention relates to a vehicle information retrieval technology, in particular to a method for retrieving vehicle information in a video image. Background technique [0002] Due to the development of video surveillance technology, more and more surveillance equipment is used to monitor roads, electronic police and urban surveillance are popularized. Various cities in the country can generate a large number of video recordings every day. This information is used to improve traffic public security departments’ The mastery of information played a very timely and important role. [0003] However, how to effectively automatically find specific and effective vehicle information in the massive video data is still technically blank, requiring human intervention, participating in a lot of work, and low retrieval efficiency. Summary of the invention [0004] In view of the inadequacies in the prior art that there is no effective automatic search for specific and ef...
