【Abstract】For the characteristics of complex adjustment and control of the dot-matrix LED high beam lighting field， this paper analyzed the lighting requirements and luminous characteristics of the dot-matrix LED high beam， and then the mapping relationship between the dot-matrix LED high beam and the vehicle front lighting light field was established based on the geometric relationship， and a complete test system was built and tested. The test results show that the proposed method has accurate control effect， good real-time performance， high reliability and easy implementation.

Key words： Dot matrix LED， High beam， Illumination field transformation， On road projection， Interaction outside vehicle
