Problems solved by technology

[0003] However, when the vehicle positioning information is inaccurate, or when the traffic lights are changed due to the change of installation location, addition or removal, and the relevant information is not updated in time in the high-precision map, it will lead to traffic lights. False detection and / or missed detection affect the effective identification of traffic lights, and thus bring hidden dangers to the driving safety of vehicles

Embodiment 1

[0024] figure 1 It is a flow chart of a method for identifying the state of a traffic light in Embodiment 1 of the present invention. The embodiment of the present invention is applicable to the situation where the vehicle recognizes information related to traffic lights, and the method can be executed by a state recognition device for traffic lights, which is implemented by software and / or hardware, and is specifically configured in the vehicle.

[0025] Among them, the vehicle specifically refers to the vehicle that needs to use the identification device to effectively identify the traffic lights before it can run normally, such as unmanned vehicles or vehicles driven by color-blind drivers.

[0026] Such as figure 1 The state recognition method of the traffic lights shown includes:

[0027] S110. Receive the information of the traffic light sent by the radio frequency tag arranged on the traffic light.

[0028] Among them, the radio frequency tag is used to store the inf...

Embodiment 2

[0036] figure 2 It is a flow chart of a method for identifying the state of a traffic light in Embodiment 2 of the present invention. The embodiment of the present invention performs additional optimization on the basis of the technical solutions of the foregoing embodiments.

[0037] Further, after the operation "recognize the status of the traffic light in the image currently captured by the camera according to the information", add "write the identification result and current time stamp of the traffic light into the radio frequency tag , for other vehicles to obtain the recognition result of the traffic light by reading the radio frequency tag", so as to realize the data sharing of the recognition result of the traffic light through the radio frequency tag.

[0038] Such as figure 2 The state recognition method of the traffic lights shown includes:

[0039] S210. Receive the information of the traffic light sent by the radio frequency tag arranged on the traffic light....

Embodiment 3

[0052] image 3 It is a flow chart of a method for identifying the state of a traffic light in Embodiment 3 of the present invention. The embodiment of the present invention performs additional optimization on the basis of the technical solutions of the foregoing embodiments.

[0053] Further, after the operation "identify the state of the traffic light in the image currently captured by the camera according to the information", add "write the information of the traffic light into the radio frequency tags of other traffic lights, To build a traffic light network" to share the information of multiple traffic lights at a traffic light intersection.

[0054] Further, after the traffic light network is constructed, "delete unusable traffic lights in the traffic light network" is added, so as to update the traffic light network by deleting unusable traffic lights.

[0055] Further, after constructing the traffic light network, add "compare the currently read traffic light network...

Abstract

The embodiment of the invention discloses a traffic indicator light state identification method, device, an electronic device and a storage medium. The method comprises the following steps of: receiving the information of the traffic indicator sent by the radio frequency tag arranged on the traffic indicator; the state recognition of the traffic light is performed in an image currently captured bythe camera according to the information. The technical scheme avoids the problem of inaccurate identification of traffic indicator lights or inaccurate identification of traffic indicator lights dueto inaccurate vehicle positioning information or delayed updating of high-precision maps, and further improves vehicle driving safety.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of unmanned driving, and in particular to a method, device, electronic device and storage medium for identifying the state of a traffic light. Background technique [0002] In the prior art, some vehicles need to use identification devices to effectively identify traffic lights before they can drive normally, such as unmanned vehicles or vehicles driven by color-blind drivers. Since the vehicle usually determines the lane where it is driving through its own positioning information, and combines the high-precision map to obtain information such as the installation position and installation height of each traffic light in the lane where the vehicle is located, so as to realize the effective positioning of the traffic light, and then through the installation The images collected by the camera on the vehicle are used for effective identification of traffic lights. [0003] However, whe...
