Embedded design of light shape detecting in vehicle headlights

The light shape detecting of vehicle headlamps is an important factor of safe driving.Along with the widely using of the devices,such as embedded system and charge coupled device,it is a good method that can bring us thrift and practicality by using the CCD and embedded platform as a group.To compare the image obtained by the CCD with the standard image we can get the position differences between the two images to rectify the light figure according to the standard one.The result of experiment shows that this system is feasible and efficient.Also the system is more integrated and intelligent compared with traditional testing methods.
