Abstract

The invention discloses a vehicle-mounted visual sensing system with matched multi-cameras. The vehicle-mounted visual sensing system with the matched multi-cameras comprises a vehicle-mounted camera signal transmission unit, a DSP processing unit, a camera type judging unit, a visual data storing unit and an image information preprocessing unit; according to the vehicle-mounted visual sensing system with the matched multi-cameras, matching of various cameras in different types including an infrared camera, a single camera, a single wide-angle camera, a binocular stereo camera, a binocular image mosaic camera, and a multi-lens image mosaic panoramic camera can be achieved, meanwhile, a vehicle-mounted visual processing scheme can be built so that a variety of compatibility visual schemes can be provided to a vehicle driving auxiliary system, and time cost and economic cost of various vehicle-mounted visual boarding can be reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted visual perception, in particular to a vehicle-mounted visual perception system adapted to multiple cameras. Background technique [0002] In recent years, with the increasing maturity of automobile driving assistance technology, various automobile auxiliary functions have been increasingly applied to mass-produced automobiles. Automobile driving assistance technology is an inevitable technical stage for the development of automobiles from "mechanization" to "intelligence"; it can provide safety guarantee for drivers' driving behavior, and at the same time improve the comfort, safety and fuel economy of vehicles. In driving assistance technology and unmanned driving technology, environmental perception is an important core component. Environmental perception technology refers to the vehicle's perception of the surrounding environment through relevant signals from sensors including cameras,...
