Embodiment Construction

[0032] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0033] see figure 1 , which is shown as a flowchart of the vehicle color recognition in the present invention. As can be seen from the figure, the present invention is carrying out the vehicle color recognition process as follows:

[0034] In the first step, the image of the head of the vehicle is acquired first.

[0035] The second step is to locate the position of the license plate and identify the color of the license plate on the acquired vehicle head image. The location and color information of the license plate is the premise of this recognition method, because most of the existing vehicle information detection systems include license plate positioning and recognition modules, so the results of license plate positioning and recognition c...

Abstract

The invention discloses a vehicle color recognition method and belongs to the field of image processing. The method includes: locating a license plate and recognizing the color of the license plate; determining a vehicle color recognition reference area according to the location and color information of the license plate; dividing vehicles into colored vehicles, black vehicles, white vehicles, sliver vehicles and gray vehicles by counting feature parameters of the reference area, such as saturation; if the vehicle is colored, separating out a colored area, and recognizing the color of the area; if the vehicle is black, white, sliver or gray, splitting the reference area, and determining the color of the vehicle by voting. Through the use of the method, the problem that the prior art is sensitive to interferences in images is solved.

Description

technical field [0001] The invention relates to image processing technology, in particular to a method for detecting vehicle information on road images, and in particular to a vehicle color recognition method. Background technique [0002] In recent years, with the rapid development of computer and Internet technology, the number of various motor vehicles has increased rapidly, and various types of information, including traffic-related information, have shown an explosive growth trend. In order to manage these information more safely and efficiently, the Intelligent Transportation System (Intelligence Transportation System) came into being. Intelligent transportation systems can play a powerful role in toll checkpoints, parking lots, and criminal tracking. Vehicle information in video images includes license plate number, vehicle color, vehicle model, etc. Vehicle color recognition plays a pivotal role in vehicle road monitoring and is an indispensable part of vehicle info...
