Abstract

The invention provides an in-vehicle monitoring system cooperation device, which comprises an IMS system and a DMS system, the IMS system and the DMS system operate independently, the IMS system comprises a first infrared lamp, a first control unit MCU and an IMS camera, the first control unit MCU is used for judging whether the external environment is daytime or night, the IMS camera is used for shooting and obtaining a color image or a black-and-white image, and the first infrared lamp is used for detecting whether the external environment is daytime or night. When the first control unit MCU judges that the external environment is at night, a signal for controlling the first infrared lamp to be turned on intermittently is generated; the first infrared lamp is used for providing infrared light for exposure of the IMS camera when the first infrared lamp is turned on, and the frequency of the first infrared lamp is controlled, so that infrared interference of the DMS system on the IMS system can be eliminated, the phenomenon of dark strips appearing on an image obtained by the IMS system is eliminated, and the image quality of the IMS system is improved. The problem that the video output by the IMS system flickers due to infrared light interference generated by the DMS system is effectively solved, the user experience is improved, and the image quality is ensured.

Description

technical field [0001] The invention relates to the technical field of in-vehicle monitoring, in particular to a multi-camera monitoring system coordination device in the vehicle. Background technique [0002] At present, most of the monitoring in the car is only the driver monitoring system (DMS). The DMS system is used to give an alarm when the driver is tired. In order to exclude the natural light during the day from affecting the algorithm detection of the DMS system, the system usually needs to use a 940 filter to cooperate. Infrared lights are used. Later, in order to improve the safety of passengers in the car, the in-vehicle monitoring system (IMS) was introduced to record the situation in the car. The system uses an RGBIR color image sensor, which can obtain color images in daylight conditions. Infrared images can be obtained with infrared lamps at night, so that the image quality obtained by the IMS system can be guaranteed no matter it is day or night. [0003] ...
