Self-adaptive light-supplementing image acquisition method for heat-insulating explosion-proof membrane of vehicle

Abstract

The invention discloses a self-adaptive light supplement image acquisition method for a vehicle heat insulation explosion-proof membrane, and relates to the technical field of HOV lane safe driving, the method adopts a two-stage continuous photographing mode, first photographing is carried out, light supplement judgment is carried out by adopting an average value of gray values of all pixel points in a side vehicle window area, and second photographing is carried out by adopting an average value of gray values of all pixel points in a side vehicle window area; and second-stage photographing is carried out when the first-time photographing does not meet the requirement, the second-stage photographing is that self-adaptive light supplementing intensity is given by using a light supplementing intensity fuzzy model according to the result of the first-time photographing, light supplementing photographing is carried out according to the light supplementing intensity, and self-adaptive light supplementing is realized. An illumination intensity detection module is not used, the problems that when the illumination intensity detection module is adopted, light intensity collection is not accurate, the light supplementing intensity is too large or too small, light supplementing is repeated, and the light supplementing intensity is not limited are solved, and the image quality of vehicle interior pictures collected by the vehicle monitoring system is improved.

Description

technical field [0001] The invention relates to the technical field of safe driving in HOV lanes, in particular to a method for acquiring self-adaptive supplementary light images of vehicle thermal insulation and explosion-proof films. Background technique [0002] While glass efficiently transmits visible light, it also inevitably transmits infrared rays (infrared radiation) that play a role in thermal effects. This infrared radiation brings great discomfort to people, especially in vehicles with large areas of glass for lighting and high-rise buildings with glass curtain walls. For example, after a vehicle stays in the hot summer sun for 1 hour, the temperature inside the vehicle can be raised to above 60°C, which brings a great energy load to the air conditioning system. Therefore, protective films that absorb and reflect large amounts of ultraviolet light have been developed for vehicle glass. The UV protection film for vehicle glass can block a considerable part of th...

AI Technical Summary

Problems solved by technology

[0006] (1) The photoresistor sensor is affected by the detection range and the ambient temperature, so it is difficult to accurately reflect the light intensity on the window surface, resulting in too large or too small fill light intensity, making the captured photo image unstable

[0007] (2) Use the light intensity information to judge the supplementary light. When the light intensity information is less than the light intensity threshold, the supplementary light unit performs supplementary light processing on the window, and performs light judgment in a loop until the light in the car reaches the light intensity threshold. Repeatedly fill in light to take pictures, which will affect the driver's driving

[0008] (3) There is no limit on the intensity of the supplementary light. When the difference between the set light intensity threshold is large, the intensity of the supplementary light is very large, and the supplementary light looks directly at the human eye, which will easily cause the driver to be dazzled and unable to see the road ahead clearly, resulting in Traffic accidents, at the same time, the damage to human eyes is relatively large
