Research on Detection Technology of Vehicle Front Environment

It is main technology approach to realize vehicle safety assistance driver system that the vehicle running environment is detected by the technology of radar and machine vision to judge the vehicle safety status and realize the status warning and control of the vehicle longitudinal and latitudinal movement. The technologies of radar and machine vision on vehicle front running environment detection are introduced in detail in the paper. The technologies are composed of the radar category and application, and the strategy of radar detecting obstacles, and the image characteristic of the vehicle application ,and the method of lane detection based on the image characteristic and model ,and the method of realizing other environment detection with an image and so on.
