Auxiliary traffic light recognition system for anerythrochloropsia drivers

Abstract

The invention provides an auxiliary traffic light recognition system for anerythrochloropsia drivers, which belongs to the technical field of image recognition and solves the problems of high cost and small applicable range of the conventional auxiliary color recognition technology. The auxiliary traffic light recognition system for the anerythrochloropsia drivers comprises an image processing module, a display module and an image acquisition device, wherein the image processing module processes original image information acquired by the image acquisition device into image information which can be recognized by the anerythrochloropsia drivers and sends the image information to the display module for displaying. A method comprises the following specific steps of: a, decomposing the pixels of the original image information on a red color channel, a green color channel and a blue color channel; b, recognizing a color; if the color is judged to be red or green, entering the step c; if thecolor is not red nor green, entering the step d; c, automatically converting the pixels into a color which can be recognized by the anerythrochloropsia drivers; and d, not processing. The auxiliary traffic light recognition system for the anerythrochloropsia drivers has high real-time performance and accuracy.

Description

technical field [0001] The invention belongs to the technical field of image recognition and relates to an auxiliary traffic signal recognition system for red-green blind drivers. Background technique [0002] According to statistics, in my country, the number of male red-green blindness patients accounts for about 7% of the total population, and the number of female red-green blindness patients accounts for about 0.8% of the total population. However, my country's traffic regulations clearly stipulate that patients with red-green color blindness are not allowed to drive motor vehicles. The main reason is that patients with red-green color blindness cannot or are not easy to distinguish the commonly used red and green traffic lights. However, since driving a car is already a daily need, in order to meet the technical needs of the lifting of the "color-blind driving ban" regulation in the future, it is necessary to develop an assisted driving system for color-blind patients. ...

AI Technical Summary

Problems solved by technology

However, this method has the problem that colors that are normally visible to a colorblind person may be perceived differently

This solution has certain limitations in detecting the exact position and operational accuracy of traffic lights in complex areas (such as urban centers), and the system has problems of high cost and difficulty

Also, the limitation of this scheme is that it cannot be used to measure when the driver wishes to detect the color of the vehicle in front or the surrounding buildings
