Embodiment Construction

[0028] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0029] refer to figure 1 , which is a traffic sign recognition method during vehicle driving provided in an embodiment of the present invention, including specific steps, which will be described in detail below in conjunction with the description.

[0030] Step S101, acquiring a driving image of a vehicle in motion.

[0031] In a specific implementation, the driving image refers to the surrounding image during the driving of the vehicle, especially the image of the moving direction.

[0032] Step S102, performing image enhancement processing on the driving image to obtain a recognition image.

[0033] In a specific implementation, image enhancement processing is performed to improve the accuracy of subsequent detection and recognition, thereby improving the accuracy of the final recognition result.

[0034] In an embodiment of the present i...

Abstract

The invention discloses a traffic sign recognition method and a device in the vehicle driving process. The method comprises the steps of acquiring a driving image in vehicle driving; performing imageenhancement processing on the driving image to obtain an identification image; performing edge detection on the identification image, and determining a to-be-determined mark conforming to a specific shape in the detection image; performing color detection on the to-be-determined signs, and the to-be-determined signs meeting the preset color gamut range are reserved as determined traffic signs; andidentifying the determined traffic sign. By the adoption of the method, the situation that recognition is omitted or irrelevant objects are mistakenly recognized as traffic signs can be avoided. A traffic safety factor is improved.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a traffic sign recognition method and device during vehicle driving. Background technique [0002] Today, the field of transportation is developing very rapidly. Therefore, people put forward higher requirements for traffic safety. [0003] In order to meet safety requirements, assisted driving systems appear. Due to the complicated traffic rules at this stage, it is difficult for people to remember the various traffic signs, or to reflect the meaning of the traffic signs in the first time during driving, so they need the help of the assisted driving system. [0004] The traffic sign recognition scheme adopted in the prior art has the situation of missing recognition, or misidentifying irrelevant objects as traffic signs. Therefore, there are certain potential safety hazards. Contents of the invention [0005] Purpose of the invention: The present invention aims to provide a...
