Abstract:
1. Night vision system for a road scene comprising: at least one projection device for emitting near infrared light towards a road scene; a first sensor for capturing a first image of the road scene, the first sensor being a colour sensor for capturing said first image without blooming, said first image being a colour image; a second sensor for capturing a second image of the road scene using the near infrared light, the second sensor being a monochrome infrared sensor, sensitive to infrared radiation from 800 nm to 1200 nm, for capturing said second image with blooming, said second image being a monochrome infrared image, said first sensor and said second sensor being synchronous or quasi-synchronous; and an image processing means for combining said colour image without blooming with said monochrome infrared image with blooming; wherein the first sensor has a sensitivity 10 to 100 times less than a sensitivity of the second sensor.
