Abstract:

The vehicle infrared imaging system uses the principle of photoelectric transformation and image recognition to form a visual image to increase the safety of driving at night. The vehicle-mounted active infrared imaging system uses semiconductor infrared laser as light emitter, uses convex lens and concave lens to project light into a wider range in front of the vehicle, and uses black-and-white CCD camera to capture images in real time. The image signal is processed by FGPA module and transmitted to the vehicle LED display screen by single chip microcomputer. The improved active infrared imaging system suggested in this paper has the advantages of large laser irradiation range, high imaging quality and real-time performance.
