Problems solved by technology
[0005] In order to solve the problem of unclear imaging of binocular cameras due to poor nighttime illumination, the technical points of the present invention are: an infrared camera lighting device for pedestrian detection, which is mainly composed of a binocular camera, an infrared lighting system and a circuit control system. The binocular camera includes a first camera and a second camera, the infrared lighting system is located between the first camera and the second camera, and the infrared searchlight beam of the infrared lighting system illuminates the reflected light of the target, and the infrared lighting system is illuminated by the first camera and the second camera. Receive, the first camera and the second camera are respectively connected to the corresponding data processing and control unit, and the infrared lighting system is connected to the infrared lighting control circuit
[0006] Beneficial effects: the purpose of the present invention is to provide a binocular pedestrian detection infrared camera lighting device at night, the device is equipped with an infrared lighting system on the binocular pedestrian detection daytime camera device, the infrared lighting system needs to meet the binocular nighttime The illumination requirement of infrared camera solves the problem that due to the poor illumination at night, the imaging of the binocular camera is not clear, which affects the detection effect of binocular pedestrians, so that the binocular pedestrian detection system can meet the requirements of night use

Embodiment Construction
[0012] 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 780nm-1000nm. The device uses 850nm or 940nm "infrared lamps" to generate infrared radiation, emits infrared light invisible to the human eye to illuminate the scene and the environment, and uses binocular ordinary low-illumination CMOS cameras to receive the infrared light reflected from the surrounding environment, so as to achieve nighttime dual Eye camera function to complete pedestrian detection. Active lighting can make full use of the narrow beam of the infrared searchlight to illuminate the target, so that the target and the background form a greater contrast 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 targeting. Near-infrared cameras are...

The infrared camera lighting device for pedestrian detection belongs to the field of binocular vision pedestrian detection. It is used to solve the problem that the image of the binocular camera is not clear due to the poor illumination at night. The technical points are: it is mainly controlled by the binocular camera, the infrared lighting system and the circuit. The system is composed, the binocular camera includes a first camera and a second camera, the infrared lighting system is located between the first camera and the second camera, and the infrared searchlight beam of the infrared lighting system illuminates the reflected light of the target, which is formed by the first camera and the second camera. The camera and the second camera receive, the first camera and the second camera are respectively connected to the corresponding data processing and control units, and the infrared lighting system is connected to the infrared lighting control circuit.
Description
technical field [0001] The invention belongs to the field of binocular vision pedestrian detection, and particularly relates to a nighttime imaging lighting device of a common low-illuminance binocular camera. Background technique [0002] With the rapid growth of motor vehicle ownership, 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, property and national economy in various countries. Among the many traffic accidents that have occurred in recent years, accidents at night or in cloudy conditions are particularly serious. It is absolutely necessary to give more attention to the problem of driving at night. 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 the main reason for the occurrence of traffi...
