To obtain sharp images an array of high-power flashing LED’s is used. For every 1mm the vehicle moves (depending on the resolution), the LED light makes a flash with a strength many times stronger than the sunlight, which removes shadows cast due to the sun.
The camera is triggered simultaneous and each line from the camera is added to the previous lines to make up one long continuous image. This eliminates the overlap algorithms that combines standard single frames.
The continuous image is stored on a computer, tagged with time and distance identifying the precise position for each part of the image.
