Vision enhancement and visibility early warning system and method based on multi-sensor foggy driving

Abstract

The invention is based on a multi-sensor foggy driving vision enhancement and visibility early warning system and method, belongs to the technical field of intelligent vehicle safety assisted driving, and includes a power supply, a transformer plug, a front infrared camera, a front millimeter wave radar, a vehicle-mounted electronic control unit module, Car displays, car audio equipment, car speakers, and vehicle speed sensors. The present invention constructs a road image classifier, a foggy or non-foggy image classifier, establishes a foggy image defogging model, obtains a clear defogging image, realizes the visual enhancement effect, constructs a visibility calculation model, judges the visibility level, and uses millimeter wave radar to measure vehicle speed Level and the level of the detected distance between vehicles in front to determine whether to provide visual and auditory warnings to the driver. This method realizes the enhanced vision of the driver and the early warning of driving visibility under the condition of low visibility in foggy days, and solves the problems of the limited irradiation range of the existing automobile fog lights in foggy days, the existence of blind spots, and the inaccurate judgment of the driver on the driving environment, etc. .

Description

technical field [0001] The invention mainly relates to the technical field of intelligent vehicle safety assisted driving, in particular to a multi-sensor-based foggy driving vision enhancement and visibility early warning system and method. Background technique [0002] Severe weather is one of the main factors that cause road traffic accidents. Among all the severe weather that is likely to cause traffic accidents, fog has the greatest impact, which often leads to speed limits or closures of expressways, delays in driving time, and even leads to chain collisions, causing huge Economic losses. In recent years, due to the severity of haze (dry) or fog (wet), visibility has even been reduced to zero (visibility less than 100 meters is usually considered zero), which is very dangerous for drivers. According to statistics, traffic accidents in fog account for about 15% of the total number of road accidents every year, but cause more than 47% of fatalities. Therefore, there is...
