Problems solved by technology

There are two problems in this method: 1) It requires high-definition video or image, and the car logo is clearly visible, but the current traffic video / image quality cannot meet the requirements; 2) The premise of car logo classification is car logo detection, that is Detect the position of the car logo in the image
Although the method based on the induction coil has the advantage of low cost, its problems are also obvious: 1) It is inconvenient to install and needs to destroy the road surface; 2) The waveform is noisy and the recognition rate is low; 3) The maintenance cost is high

Embodiment Construction

[0028] In the present invention, vehicle brand recognition is performed based on images. Its input is a single image or a frame of a video.

[0029] figure 1 An overview of the flowchart of the image-based vehicle brand recognition method according to the embodiment of the present invention is shown.

[0030] Image-based vehicle brand recognition method of the present invention comprises the following steps:

[0031] (a) License plate detection: In step 101, the position of the license plate in the input image is detected. In this step, license plate detection is performed on the input image, and the output is the position of the license plate in the image. In one embodiment, the location includes the coordinates of the license plate within the image, the height of the license plate and the width of the license plate.

[0032] One image can output multiple license plate positions. Such as figure 2 As shown in the schematic diagram of license plate detection, the image o...

Abstract

The invention provides a method and system for recognizing a vehicle brand based on an image. The method and system can carry out multi-dimensional position detection in the image to fast recognize the vehicle brand, are high in detection rate and have little misinformation.

Description

technical field [0001] The invention relates to vehicle identification, in particular to vehicle brand identification. Background technique [0002] In a city's intelligent transportation system, vehicle brand recognition is an important component. It can automatically identify the brand information of the vehicle, such as whether a certain car is Volkswagen, Ford or Liberation. Vehicle brand recognition is widely used in traffic management systems, public security systems and commercial systems. In the traffic management system, according to the distribution and density of different types of vehicles in the road network, different signal light adjustments, traffic police configurations, etc. can be carried out; in the public security system, the most direct application is the detection of licensed vehicles. If the brand recognized by a vehicle is inconsistent with the record of its license plate in the public security system, the vehicle may be a licensed vehicle; in the ...
