Embodiment 1

[0030] The method for detecting a traffic light according to an embodiment of the present disclosure will be introduced below.

[0031] In the prior art, when detecting traffic lights, first obtain the traffic light information bound to the lane where the current vehicle is located through the high-precision map, project the traffic light frame to the image plane, and expand the traffic light frame according to the projected traffic light frame. Larger ROI, call the model in the ROI for traffic light detection, then match the detection frame with the projection frame and complete the output, but this method completely relies on the high-precision map. If the high-precision map of the current vehicle driving area is not available, Or the traffic lights do not match the information in the high-precision map due to road maintenance or replacement and other reasons, which will invalidate the traffic light detection module and prevent normal traffic light detection. At the same time...

Embodiment 2

[0088] The detection method for a traffic light of the present disclosure will be further introduced below with reference to the preferred embodiments.

[0089] At present, when detecting traffic lights, it is necessary to obtain the location information of the traffic lights through a high-precision map, and project the traffic lights to an image plane through coordinate transformation for subsequent processing. Reliance on high-precision maps will significantly increase the cost of vehicles. At the same time, this type of solution will require high-precision maps to ensure real-time performance. After the location and type of traffic lights change, there will be functional failures and other situations, posing a greater safety hazard.

[0090] The scheme designed in the present invention is separated from the dependence on the high-precision map, and realizes the condition of no high-precision map by counting and voting on the detection results, using historical frame informa...

Embodiment 3

[0153] Embodiments of the present disclosure also provide a method for executing figure 1 The method of detecting a traffic light of the illustrated embodiment is an apparatus for detecting a traffic light.

[0154] Figure 5 is a schematic diagram of a device for detecting traffic lights according to an embodiment of the present disclosure, such as Figure 5 As shown, the apparatus 50 for detecting traffic lights may include: a collection unit 51 , a selection unit 52 , a prediction unit 53 , a first determination unit 54 , and a second determination unit 55 .

[0155] The collection unit 51 collects the vehicle motion information and the current frame image of the vehicle during the driving process, wherein the frame image is obtained by shooting a camera installed on the vehicle;

[0156] Selecting unit 52, selects the previous frame image adjacent to the current frame image, and identifies at least one traffic light to be tracked from the previous frame image;

Abstract

The invention provides a traffic light detection method and electronic equipment. The method can comprise the steps that vehicle motion information and a current frame image in the driving process of a vehicle are collected, and the frame image is shot through a camera installed on the vehicle; selecting a previous frame of image adjacent to the current frame of image, and identifying at least one traffic light to be tracked from the previous frame of image; based on the position information of the to-be-tracked traffic light in the previous frame of image and the vehicle motion information of the vehicle, predicting to obtain a predicted position of the to-be-tracked traffic light in the current frame of image; determining a plurality of candidate traffic lights in the current frame image based on the predicted position of the traffic light to be tracked in the current frame image; and determining a target traffic light from the plurality of candidate traffic lights. According to the invention, the technical problem of low reliability of traffic light detection is solved.

Description

technical field [0001] The present disclosure relates to the fields of artificial intelligence and pattern recognition, and in particular, to a method and electronic device for detecting traffic lights. Background technique [0002] At present, when detecting traffic lights, first obtain the traffic light information bound to the lane where the current vehicle is located through the high-precision map, project the traffic light frame to the image plane, and expand a larger sense of the traffic light frame according to the projected traffic light frame. Region Of Interest (ROI), in which the model is called for traffic light detection, and then the detection frame is matched with the projection frame to complete the output, but this method completely relies on high-precision maps. If the current vehicle is driving The regional high-precision map is unavailable, or the traffic lights do not match the information in the high-precision map due to road maintenance or replacement ...
