Embodiment Construction

[0089] In order to make the present invention more clear, a detailed explanation will now be given in conjunction with the accompanying drawings and embodiments.

[0090] The signal lights for relocation in the current embodiment of the present invention are relatively common traffic lights, including a red light and a green light. For traffic lights, the method of the current embodiment of the present invention is as follows Figure 4 As shown, the steps are as follows:

[0091] In step 1, the relocation area of ​​each signal light is respectively obtained, and the relocation area includes a complete signal light.

[0092] The traffic lights of the current embodiment are traffic lights, including a red indicator light ( Figure 3a The rectangular area A shown 1 Framed lights) and green lights for traffic ( Figure 3b The rectangular area A shown 2 framed light). The original position of each signal light and the size, shape and color of the indicator light are configure...

Abstract

The invention discloses a color time varying characteristic-based traffic light relocating method, the method is used for relocating the traffic lights in images, and the traffic lights comprise a plurality of indicator lights which are mutually matched to display traffic signals. The traffic light relocating method comprises the following steps: respectively obtaining the relocating area of each indicator light; and by taking a plurality of frames as a locating period, calculating the color component strength of each pixel in the relocating area of the image of each frame in a single locating period; when each locating period is ended, deleting the pixels which do not satisfy the characteristics of the indicator lights, finding the center points of the indicator lights according to the retained pixels after the deletion, and combining the center points with the sizes of the indicator lights to determine the positions of the indicator lights when the current locating period is ended. The invention furthermore discloses a corresponding traffic light relocating device.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a traffic signal light relocation method and device based on color time-varying features. Background technique [0002] Electronic police cameras need to detect the status of traffic lights in real time in order to capture the behavior of running a red light. Traffic lights include a plurality of indicator lights, such as common traffic lights, including red indicator lights (red lights) and green indicator lights (green lights). When the on-site environment does not allow the installation of a light detector, it is necessary to perform real-time traffic signal light detection based on the video content through the image processing light method in the electric police camera. [0003] Such as figure 1 As shown, the application scene of the electronic police camera is generally an intersection, the traffic lights are far away from the camera, and the area of ​​the signal lights is...
