Embodiment 1

[0048] figure 1 It is a structural diagram of a traffic sign display device provided in Embodiment 1 of the present invention. The traffic sign display device can be used to be recognized by the self-driving vehicle, so as to provide traffic sign information to the self-driving vehicle. Such as figure 1 As shown, the device includes a pattern display area 10, wherein: the pattern display area 10 is used to display an electronic identification pattern, and the electronic identification pattern is associated with the current traffic sign information and the forecast traffic sign information. The electronic identification pattern is a two-dimensional code pattern and / or a URL character pattern.

[0049] Among them, the two-dimensional code pattern, also known as the two-dimensional barcode pattern, is a black and white (or color and white) pattern distributed on a plane (two-dimensional direction) according to certain rules to record data symbol information. . The URL charact...

Embodiment 2

[0055] figure 2 It is a structural diagram of a traffic sign display device provided in Embodiment 2 of the present invention. Such as figure 2 As shown, this embodiment is based on the above embodiments, optionally, the traffic sign display device includes: a pattern display area 201 and a communication unit 202 . Wherein, the pattern display area 201 is used to display an electronic identification pattern, the electronic identification pattern is associated with the current traffic sign information and the forecast traffic sign information, and the electronic identification pattern is a two-dimensional code pattern and / or a website character pattern. The communication unit 202 receives the update instruction issued by the server, and updates the electronic identification pattern displayed on the pattern display area 201 according to the update instruction.

[0056] Wherein, the pattern display area 201 can be, for example, formed by patterns composed of light emitting di...

Embodiment 3

[0060] image 3 It is a flow chart of a traffic sign recognition method provided in Embodiment 3 of the present invention. The method in this embodiment can be executed by a vehicle-mounted control device, which can be implemented by means of hardware and / or software, and can generally be integrated into a vehicle-mounted control device. The method of this embodiment specifically includes:

[0061] S110. Obtain an electronic identification pattern collected from the traffic sign pattern display area, wherein the electronic identification pattern is a two-dimensional code pattern and / or a website character pattern.

[0062] Among them, compared with recognizing the existing traffic sign patterns, the on-vehicle control device has the advantage of being able to quickly read and recognize the two-dimensional code patterns and / or URL character patterns.

[0063] S120. Recognize the electronic recognition pattern, and acquire associated current traffic sign information and advanc...

Abstract

The invention discloses a traffic sign display device, a traffic sign identification method and device, equipment and a medium. The traffic sign display device includes a pattern display area, whereinthe pattern display area is used for displaying an electronic identification pattern, the electronic identification pattern is associated with the current traffic sign information and the advance notice traffic sign information, and the electronic identification pattern is a two-dimensional code pattern and / or a web address character pattern. The method is advantaged in that problems of low identification standardization degree of traffic signs and less information carrying amount of texts and graphs in the prior art are solved, the effect of large amount of information carried by the electronic identification pattern is realized, the traffic signs are improved, and achievement of the automatic driving technology is facilitated.

Description

technical field [0001] Embodiments of the present invention relate to vehicle automatic driving technology, and in particular to a traffic sign display device, recognition method, device, device and medium. Background technique [0002] With the development of autonomous driving technology, the automatic perception and automatic recognition capabilities of vehicles are getting stronger and stronger. It not only puts forward requirements for hardware and software improvement of the vehicle itself, but also puts forward new requirements for the social road environment. [0003] At present, traffic signs are mainly text and graphics, mainly for natural drivers, for drivers to see and recognize. However, for self-driving vehicles, the standardization of text and graphic traffic sign recognition is low, and the amount of information carried is small. Contents of the invention [0004] Embodiments of the present invention provide a traffic sign display device, recognition meth...
