Embodiment Construction

[0022] In order to make the technical solution of the present invention more clear and understandable, the solution of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0023] figure 1 It is a flow chart of an embodiment of the yellow label vehicle detection method of the present invention. Such as figure 1 As shown, for each acquired vehicle front-facing snapshot image (such as a traffic checkpoint front-facing vehicle image), it can be processed in the manner shown in steps 11-13 below.

[0024] Step 11: Determine the region of interest including the window sticker from the front-facing snapshot of the vehicle.

[0025] The above-mentioned region of interest usually refers to the window region.

[0026] The way to determine the region of interest from the forward captured image of the vehicle can be:

[0027] Carry out license plate detection in the forward captured image of the vehicle;

Abstract

The invention discloses a method and device for detecting a yellow-labeled vehicle: for each acquired vehicle frontal snapshot image, an area of ​​interest including a vehicle window label is respectively determined from the vehicle frontal snapshot image; from the interest area M sub-images to be analyzed are detected in each sub-image to be analyzed, and each sub-image to be analyzed includes a rectangular window label, M is a positive integer; determine whether there is a yellow environmental protection sign in each detected rectangular window label, if yes , then the vehicle in the front-facing snapshot image of the vehicle is determined to be a yellow-labeled vehicle. By applying the solution of the present invention, it is possible to effectively identify whether the vehicle in the image is a yellow label vehicle.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method and device for detecting yellow-label vehicles. Background technique [0002] Yellow label vehicle is another name for high-pollution emission vehicles. It refers to gasoline vehicles that do not meet the national I emission standards, or diesel vehicles that do not meet the national III emission standards. Because they are affixed with yellow environmental protection signs, they are called yellow label vehicles. . [0003] Due to the high pollution and low emissions of yellow-label vehicles, environmental protection departments or transportation departments usually impose special regulations on such vehicles to restrict them, such as restricting their driving in certain road sections / areas. The yellow-labeled vehicles driving on these road sections / areas are detected in time in the image. [0004] However, in the prior art, there is no way to effectively dete...
