Abstract

The invention discloses a virtual license plate-based unlicensed vehicle identification method. The method is characterized by comprising the steps of 1, establishing virtual license plates: performing vehicle detection based on videos or images to obtain vehicle close-up images, performing feature extraction on the vehicle images, generating the virtual license plates, and establishing a virtual license plate library; and 2, identifying the virtual license plate library: performing target vehicle detection based on the videos or the images to obtain a target vehicle close-up image, performing feature extraction on the target vehicle image, generating a virtual license plate, and comparing the virtual license plate with the virtual license plate library. According to the method, a unique vehicle virtual license plate is generated for each vehicle based on image identification, so that the target vehicle can be effectively searched and retrieved without license plate identification; and therefore, the method is of positive significance on various traffic applications such as highway fee evasion check, red light running of unlicensed vehicles, quick search of accident vehicles and the like.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to a method for identifying an unlicensed vehicle based on a virtual number plate, which is an important application in the field of traffic applications. Background technique [0002] With the rapid development of my country's transportation industry and the large-scale increase of civilian vehicles, it is particularly important to classify and manage driving vehicles through images, especially for the identification and management of unlicensed vehicles. At present, there is no mature unlicensed vehicle identification solution, because the solution needs to accurately obtain information such as the location and size of the vehicle, vehicle brand, annual inspection bid, pendant, etc., so as to uniquely identify the same vehicle. Only in this way can the retrieval and management of unlicensed vehicles be carried out effectively. However, due to the incomplete feature description in th...
