Embodiment Construction
[0011] The binocular camera night imaging lighting device based on the pedestrian detection system is an active infrared technology device and a near-infrared camera sensitive device with a wavelength of 780 nm to 1000 nm. The device uses 850nm or 940nm "infrared lamps" to generate infrared radiation, emits infrared light invisible to the human eye to irradiate the scene and the environment, and uses binocular ordinary low-light CMOS cameras to receive the infrared light reflected back from the surrounding environment, so as to realize night-time dual-viewing. Eye camera function to complete pedestrian detection. Active lighting can make full use of the narrow beam of the infrared searchlight to irradiate the target, so that the target can form a large contrast with the background and stand out in the field of view. Therefore, it has broad application prospects in nighttime assisted driving systems, nighttime binocular pedestrian detection and nighttime aiming. Near-infrared ...

The invention discloses an LED array lamp type selection calculation method of a binocular infrared camera shooting illumination system of a vehicle-mounted pedestrian detection system. The method comprises the steps that the luminous flux of the maximum exposure time of an image sensor is calculated; illumination of a lighting system of a pedestrian detection infrared camera lighting device is calculated. The LED array lamp type selection calculation method belongs to the field of binocular vision pedestrian detection, and is used for solving the problem of unclear imaging of a binocular camera due to poor illumination at night.
Description
technical field [0001] The invention belongs to the field of binocular vision pedestrian detection, and in particular relates to a nighttime imaging lighting device and method for common low-illuminance binocular cameras. Background technique [0002] With the rapid growth of the number of motor vehicles, it has brought great convenience to people's life and travel, but the resulting road traffic accidents have caused huge losses to people's lives, properties and national economies in various countries. Among the many traffic accidents that have occurred in recent years, the accidents that occurred at night or under cloudy conditions are particularly serious. It is absolutely necessary that more attention be paid to the problem of night driving. There are two main factors that cause the danger of driving at night. One is the visual factor. Due to the poor light at night, the driver cannot see the road conditions clearly and cannot notice the potential danger ahead. This is ...
