Embodiment 1

[0030] see figure 1 The flow chart of a road sign recognition method shown in the figure can be applied to a processing terminal, such as a vehicle terminal, a mobile terminal or a background server, but is not limited to it. The method is based on a pre-trained road sign recognition model, see figure 1 , the method includes the following steps:

[0031] Step S101, acquiring an image to be detected.

[0032] For example, multiple cameras with different angles can be installed on the vehicle, and images in various scenes can be obtained through these cameras, and the images are the images to be detected.

[0033] Step S102, input the image to be detected into the pre-trained road sign recognition model.

[0034] Wherein, the above-mentioned road sign recognition model is obtained through training based on a sample image set, and the sample image set includes sample images with interference items. The interference item may include interference caused by factors such as motio...

Abstract

The invention provides a road sign recognition method and device and electronic equipment, and relates to the technical field of image processing. According to the scheme, the method comprises: inputting an obtained to-be-detected image into a pre-trained road sign recognition model, so as to carry out the road sign recognition of the to-be-detected image, wherein the road sign recognition model is obtained by training based on a sample image set (the sample image set contains a sample image with an interference item), so that the road sign recognition model can effectively eliminate the interference item in the image and learn the road sign in the image foreground. Therefore, when the road sign recognition model is used for recognizing the to-be-detected image, the road sign in the imagecan be effectively recognized under the condition that interference items exist, and the accuracy of road sign detection is improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a road sign recognition method, device and electronic equipment. Background technique [0002] With the continuous development of the field of intelligent transportation, there are more and more researches on the detection and recognition of road signs. At present, in the detection and recognition of road signs, some fixed image features are generally selected from the captured images, such as the color features and shape features of road signs, to analyze road signs. However, in actual traffic application scenarios, the image acquisition process may be affected by factors such as motion blur, background interference, weather conditions, and shooting angles. This method cannot effectively identify the road signs in the image, which affects the accuracy of road sign detection. Contents of the invention [0003] In view of this, the purpose of the present invention is ...
