Problems solved by technology
[0005] The present invention solves the problem that binocular camera imaging is not clear due to the poor illumination at night. 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 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 ...

Disclosed is a pedestrian detection infrared camera lighting device. The device belongs to the field of binocular vision pedestrian detection. The problem that the night illumination is poor, imagingof the binocular camera is unclear is solved. Technical key points are as follows: the device is mainly composed of a binocular camera, an infrared illumination system and a circuit control system. The binocular camera comprises a first camera and a second camera; the infrared lighting system is located between the first camera and the second camera. wherein an infrared searchlight beam of the infrared lighting system irradiates reflected light of a target and is received by the first camera and the second camera, the first camera and the second camera are respectively connected with the corresponding data processing and control unit, and the infrared lighting system is connected with the infrared lighting control circuit.
Description
technical field [0001] The invention belongs to the field of binocular vision pedestrian detection, in particular to a nighttime imaging lighting device for a common low-light binocular camera. 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 to pay more attention 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 the main reason for traffic accide...
