Abstract

A vehicle identification method and system are disclosed. The method includes: obtaining appearance information of the inspected vehicle, and obtaining exterior characteristics of the vehicle based on the appearance information; obtaining a transmission image of the vehicle, and obtaining interior characteristics of the vehicle based on the transmission image; forming a description of the vehicle based on at least the exterior characteristics and the interior characteristics; And using the description to determine the model of the vehicle from the model database. This scheme uses a variety of modal information fusion, especially the introduction of perspective images, and combines internal structure information with appearance information to achieve more practical vehicle identification.

Description

technical field [0001] Embodiments of the present invention relate to vehicle vehicle identification technology, in particular, to methods and systems for vehicle vehicle identification using image processing and pattern recognition technologies in the fields of intelligent transportation and security inspection. Background technique [0002] At present, intelligent transportation and safety inspection have been widely used, and related concepts have been well known by the public. In these fields, car model recognition plays an important role. In fact, the car model identification problem itself is not well defined. This is caused by the wide range of applications involved and the great differences in the implementation environment, means and purposes. Generally speaking, the identification to obtain the unique information of the vehicle, such as the license plate number recognition system, is defined as "vehicle identification". The vehicle type identification here refer...
