Problems solved by technology

At present, due to the low efficiency of manually marking the traffic lights corresponding to each lane, it is possible to determine the traffic lights corresponding to each lane by writing a matching algorithm. Although this method can improve the matching of traffic lights and lanes to a certain extent Efficiency, but the universality of the matching algorithm is usually poor, and the threshold in the matching algorithm needs to be adjusted for different traffic scenarios, and the process of adjusting the threshold is cumbersome, which also affects the matching efficiency of traffic lights and lanes

Embodiment 2

[0040] see figure 2 A schematic flowchart of a method for matching traffic lights and lanes is shown, the method mainly includes steps S202 to S206:

[0041] In step S202, the images in the traffic collection video are marked to obtain a traffic image marked with light area frames corresponding to a plurality of traffic lights and a plurality of fitting lanes.

[0042] Traffic collection video can be understood as traffic monitoring video, which can be collected by collection equipment in practical applications, wherein the collection equipment can include equipment with shooting functions (such as cameras, etc.), and the collection equipment can be deployed within the preset range of traffic lights In the area, the traffic acquisition video including traffic lights and lanes can be collected in real time by adjusting the shooting angle of the acquisition device; the light area frame can be understood as the bounding box of the traffic light in the image of the traffic acquis...

Embodiment 3

[0089] Regarding the method for matching traffic lights and lanes provided in Embodiment 2, the embodiment of the present invention provides a matching device for traffic lights and lanes, see Figure 9 A structural schematic diagram of a matching device for a traffic light and a lane is shown, the device mainly includes the following parts:

[0090] The labeling module 902 is configured to label images in the traffic collection video, and obtain traffic images labeled with light area frames corresponding to multiple traffic lights and multiple fitted lanes.

[0091] The determination module 904 is configured to determine the departure lane corresponding to the vehicle based on the traffic image containing the vehicle and the vehicle is located on the fitting lane.

[0092] The color acquisition module 906 is configured to acquire the signal color represented by each light area frame when the vehicle leaves the departure lane.

[0093] The matching module 908 is configured to...

Abstract

The invention provides a traffic light and lane matching method and device and electronic equipment, and the method comprises the steps: marking an image in a traffic collection video, and obtaining atraffic image marked with light region frames corresponding to a plurality of traffic lights and traffic images of a plurality of fitting lanes; determining a departure lane corresponding to the vehicle based on the traffic images which contain the vehicle and the vehicle is located on the fitting lane; when the vehicle leaves the driving-off lane, acquiring a signal color represented by each lamp area frame; and performing matching processing on each traffic light and each fitting lane based on the signal color represented by each light area frame and the departure lane corresponding to eachvehicle to obtain a fitting lane corresponding to each traffic light. The method and device have high universality, the matching process of the traffic light and the lane can be effectively simplified, and then the matching efficiency of the traffic light and the lane is effectively improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a matching method, device and electronic equipment for traffic lights and lanes. Background technique [0002] There are many vehicles driving on the road traffic network. In order to better regulate the vehicles on the road, lanes and traffic lights are usually arranged on the road, and traffic videos on the road are collected through traffic monitoring to realize automatic violation detection and monitoring. Road condition analysis, among which, the prerequisite for automatic violation detection and road condition analysis is to clarify the traffic lights that vehicles on each lane should obey. At present, due to the low efficiency of manually marking the traffic lights corresponding to each lane, it is possible to determine the traffic lights corresponding to each lane by writing a matching algorithm. Although this method can improve the matching of traffic lights and...
