Problems solved by technology

[0002] At present, some panoramic overlooking images of vehicles and their surroundings are generated such as Chinese patent (CN1412047A) by installing multiple cameras around the vehicle to perform image synthesis to generate panoramic overlooking images. CCD or CMOS photosensitive cameras are used for image generation. Due to the focal length of the lens and the size of the display, the driver cannot accurately judge the exact distance of the targets (pedestrians, vehicles and obstacles) around the motor vehicle. In addition, the device can be used normally during the day, but at night I can't see my surroundings clearly.
Due to driving at night, the road conditions in front of the motor vehicle will be illuminated by the headlights of the motor vehicle, but there will be no light in the left, right and rear directions of the motor vehicle, which will produce underexposed black. Due to the illumination of the headlights of the oncoming vehicle, the front image will be overexposed and white. In this case, the synthetic panoramic image of the vehicle and its surrounding environment is meaningless to the driver. Inability to see clearly the surroundings of the motor vehicle

Abstract

This invention relates to an observing and recording device for running of vehicles day and night, which installs multiple sets of thermal image system devices right and left, back and front of a car to pick up and collect targets at each direction around the car to provides drives to see very clear panorama planforms of the car and its ambient and direct -view images of the running direction of the car and measure the accurate distance, direction and speed of targets of the car to alarm when a target arrives at the safety distance to prompt drivers to pay attention and take necessary measures, and records images when the car starts up to record all images of a traffic accident when a traffic accident happens. Besides, this invention has the function of satellite localization and media play, which can be installed either on vehicles or ships.

Description

technical field [0001] The invention relates to an observation and recording device for day and night driving of a motor vehicle, in particular to positioning, distance measurement, image synthesis processing, displaying infrared thermal At the same time, it also provides the driver with the panoramic overlooking image of the thermal imaging camera of the motor vehicle and its surrounding environment. Once a traffic accident occurs, it can completely record the whole story of the traffic accident. Background technique [0002] At present, some panoramic overlooking images of vehicles and their surroundings are generated such as Chinese patent (CN1412047A) by installing multiple cameras around the vehicle to perform image synthesis to generate panoramic overlooking images. CCD or CMOS photosensitive cameras are used for image generation. Due to the focal length of the lens and the size of the display, the driver cannot accurately judge the exact distance of the targets (pedes...
