Method for preventing vehicle from deviating from navigation

Abstract

Provided is a method for preventing vehicle from deviating from navigation. The method comprises the following steps: 100, obtaining an original image of a front road of a vehicle; 200, processing theoriginal image to obtain a processed image, the processed image at least including a left traffic lane and a right traffic lane on two sides of the road where a vehicle travels; 300, in the processedimage, if the distance or angle between the vehicle and the left traffic lane and the distance or angle between the vehicle and the right traffic lane being the same, proving that the vehicle does not deviate; if not, the vehicle deviating on the road, and sending a prompt message to a driver of the vehicle. In the method, firstly, the original image is processed to obtain the processed image, and then in the processed image, through comparing the distance between the vehicle and the left traffic lane with the distance between the vehicle and the right traffic lane, or through comparing the angle between the vehicle and the left traffic lane with the angle between the vehicle and the right traffic lane, whether the vehicle is deviated is determined. The method is advantaged by not being influenced by weather environment, being able to accurately know whether the vehicle is deviated on the road, and being low in error.

Description

technical field [0001] The invention relates to the technical field of safe driving of vehicles, in particular to a method for preventing vehicles from deviating from navigation. Background technique [0002] With the improvement of people's living standards, the popularity of vehicles is getting higher and higher, and the safety issues in the driving process are particularly important. There are generally lanes drawn on the left and right sides of the road, and vehicles need to drive between the left and right lanes during driving. However, in the process of driving a vehicle, the driver often observes whether the vehicle deviates from the road with human eyes, but cannot accurately know whether the vehicle deviates from the road, especially in the case of bad weather conditions, such as night, dawn, rainy days, sunny days, On cloudy days, snowy days, windy days, etc., the error caused by observation with human eyes will be greater, and it is more likely to cause unsafe ac...
