Research and development of intelligent headlight test system based on machine vision

As an important component of automotive vehicles, automotive headlights have evolved from a traditional single-light headlight to an active safety lighting system. Intelligent headlight, such as matrix LED headlight has gradually become the mainstream of headlight lighting systems for their good lighting visibility and easy to control combined light forms. It is import to do research on the test method of intelligent headlight for quality assurance. In this paper, an automatic test system was designed, included light shape image processing and machine vision system development. The test results show that the test system can detect the headlight product characteristics well and efficiently.
