The method involves lighting the road side and using a vehicle which a radiation device. The radiation produced can be IR. An image is taken of the road side with a camera (1) which is sensitive to the radiation and addressable line by line. The camera is positioned vertically and can be rotated about an axis so that each line is entirely formed in an image zone for which a uniform gain is required. The gain for each line is controlled (6) according to predetermined criteria to obtain a dynamic image. |
