Abstract

The invention provides a vehicle-mounted night vision auxiliary driving imaging optical system. The internal structure of a shell comprises a night imager assembly, a thermal imager assembly and a color camera assembly. a controller comprises a touch screen and operation keys, and the operation keys are used for achieving rotation operation of the shell structure by controlling the motor; a computer is coupled with the controller and is used for controlling an imaging mode and parameters of the video screen display equipment through the touch screen; a multispectral optical filter is arranged between the optical lens and the image sensor, and the multispectral optical filter comprises a first optical filtering part, a second optical filtering part and a hollow part; a processor is electrically connected with the image sensor of the night imager assembly and the image sensor of the thermal imager assembly, and is used for carrying out cross correlation fusion processing on images formed by the two image sensors.

Description

technical field [0001] The invention relates to a vehicle-mounted night vision assisted driving imaging optical system, which belongs to the technical field of optical systems and image communication. Background technique [0002] According to the latest survey of the World Health Organization, traffic accidents account for a large proportion of deaths in many countries. About 1.25 million people die in road traffic accidents every year, and more than half of them are vulnerable road users. Although there are fewer vehicles on the road at night, the proportion of traffic accidents at night is very high. [0003] An effective strategy to reduce the number of casualties in such road traffic accidents is to use automotive night vision assisted driving systems to give early warning or help drivers make decisions in dangerous driving situations. The current automotive assisted driving system uses different sensor systems based on radar, laser ranging radar, camera and ultrasonic...
