Problems solved by technology

[0004] Although the aforementioned technology can assist in judging the state of the vehicle drifting from the lane, it does have the problem that it cannot be correctly identified in accordance with the weather conditions
This is because when cameras are used to monitor lane deviation, if it is raining at night, due to water accumulation on the road, the road surface is likely to reflect the light source of street lamps or car lights due to accumulation of water, making it difficult to judge after capturing the image. , causing misjudgment

Abstract

The invention discloses a method for warning lane migration, which chooses information acquiring source based on the climate and ambient brightness to reduce the misjudgment in image analysis of lanemigration. By using the method, the invention further provides a device for warning lane migration, which can obtain the information around the vehicle and under the vehicle respectively by applying two information acquiring units. The information is transmitted to an information processing and controlling unit to carry out calculus in order to accurately judge the lane migration to avoid the misjudgment caused by the influence of environment. The information processing and controlling unit can choose the image information detected by the information acquiring unit based on either the climateor the ambient brightness to analyze the vehicle migration. When certain abnormal condition of migration happens, the warning device can form warning to remind the driver to pay attention.

Description

technical field [0001] The present invention relates to a warning method and device, in particular to a lane departure warning that can judge the state of the surrounding environment of the vehicle to accurately grasp the information of the lane deviation, so as to avoid misjudgment caused by the influence of the environment Methods and devices. Background technique [0002] According to the analysis of the Statistics Office of the Ministry of Communications of Taiwan Province of China, among the main causes of A1 traffic accidents in Taiwan and Fujian (A1 refers to traffic accidents that cause death on the spot or within 24 hours), there have been three consecutive years (90 to 92 years) "Not paying attention to road conditions" is the most common. This shows that most of the car accident causes are inattentive, careless or inattentive of the driver. Human concentration is easily affected by various factors, and it is difficult to maintain a high degree of vigilance all t...
