Panoramic surround view system for cars and adaptive light supplementing method thereof

Abstract

The invention discloses a panoramic surround view system for cars and an adaptive light supplementing method thereof, in the method, by performing grey level histogram brightness analysis on an original video image captured by surround view cameras mounted at two sides of a car body, intensity of external environment light of the surround view cameras mounted at left and right sides of the car body is judged, whether to perform light supplementing operation for the surround video cameras is decided adaptively, a surround video camera light supplementing lamp group is arranged, and thus, adaptive light supplementing for the panoramic surround view system is realized. According to the method and the system provided by the invention, a function of adaptively supplementing light for the surround view cameras mounted at two sides of the car body is realized, and a defect of failure of the panoramic surround view system in a scene where the external light is not enough or an obvious externallight source is not provided is overcome effectively.

Description

Technical field: [0001] The present invention relates to the field of automobile safety and intelligent vehicle research, in particular, the present invention relates to a panoramic view system for a vehicle with an adaptive supplementary light function, and using the panoramic view system for a vehicle with an adaptive supplementary light function to automatically A panorama method adapted to fill light. Background technique: [0002] With the continuous development of economy and transportation, automobiles have become an indispensable means of transportation for people. In recent years, the rapid increase of automobiles has made urban roads and community parking increasingly congested, making drivers limited by objective conditions such as vision and narrow parking spaces when parking, and collision accidents are extremely prone to occur, resulting in unnecessary losses. Most of the vehicle scratching incidents are caused when entering and exiting the parking space and g...

Problems solved by technology

[0006] In order to solve the problem that the surround view cameras installed on the left and right sides of the vehicle body cannot capture surrounding images in the current panoramic surround view system when the external light is insufficient or even there is no obvious external light source, the present invention provides a vehicle with adaptive supplementary light function Panoramic surround view system and adaptive supplementary light method thereof, according to the vehicle panoramic surround view system with adaptive supplementary light function and adaptive supplementary light method thereof of the present invention, the images captured by the surround view cameras mounted on both sides of the vehicle body can be Carry out brightness analysis of the gray histogram, and then realize adaptive light supplement for the surround-view camera, and perform brightness equalization on the panoramic image after the light supplement
