Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] refer to figure 1 , a vehicle type identification method based on license plate information and multi-channel video information fusion of vehicle outline, said vehicle type identification method comprises the following steps:

[0036] 1) Using multiple cameras installed in different directions to obtain video images, to obtain side images of the vehicle and images of the front or rear of the vehicle;

[0037] 2), implement the detection, tracking and separation of vehicle images;

[0038] 3) For the images collected by cameras installed in different positions, use corresponding methods to generate classification results, the process is as follows:

[0039] 3.1 For the image of the front or rear of the car, the license plate location, using the color and aspect ratio information of the license plate to obtain the type information of the vehicle;

[0040] 3.2 F...

Abstract

The invention provides a vehicle category identification method based on multi-channel video information fusion of license plate information and vehicle profiles. The method comprises the following steps of 1), obtaining video images by adopting a plurality of cameras mounted in different positions, and obtaining a vehicle side image and a vehicle head or tail image; 2), detecting, tracking and separating the vehicle images; 3), generating classification results by adopting corresponding methods for the images acquired by the cameras mounted in the different positions; and 4), comparing detection results of different methods, and adopting a simple voting information fusion mechanism. According to the vehicle category identification method based on the multi-channel video information fusion of the license plate information and the vehicle profiles, provided by the invention, the accuracy is effectively improved.

Description

technical field [0001] The invention relates to a vehicle type identification technology, in particular to a vehicle type identification method. Background technique [0002] Intelligent transportation systems require vehicle detection and type recognition. Automatic vehicle identification is carried out by mutual recognition between vehicle-mounted equipment and ground base station equipment, and is mainly used in charging systems, such as AE-PASS system, ETC system, GPS positioning, etc. Automatic vehicle classification is to classify vehicles by detecting the inherent parameters of the vehicle itself and using classification recognition algorithms under certain vehicle classification standards. [0003] Vehicle identification includes vehicle license plate recognition, vehicle color recognition, vehicle model recognition, vehicle logo recognition, etc. At present, the most mature is the recognition of vehicle license plates, and has been widely used in electronic police,...
