Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0040] For the vehicle-mounted infrared camera with monitoring function, the infrared LED module is separated from the infrared camera module, which needs to be connected by multiple wire harnesses, and the structure is complicated; the infrared LED module needs to be installed together with the camera module, which is not conducive to the installation of the whole vehicle; the wiring harness and the infrared LED module There are many mechanical materials suc...

Abstract

The invention relates to the technical field of a vehicle-mounted camera, in particular to a driver monitoring infrared camera device and an image brightness control method, comprising a processor unit and an infrared camera module. The infrared camera module comprises a power module, a lens, an image sensor, an image processing module, an LVDS serializer and a second coaxial connector connected in sequence, and an LED, an LED driving module, a second B2B connector and a first B2B connector connected in sequence. The second coaxial connector and the first B2B connector are powered by the powersupply module; The image processing module is respectively connected with the LED driving module and the first B2B connector. The second coaxial connector is connected to a first coaxial connector ofthe processor unit. The invention aims to provide a driver monitoring infrared camera device, which solves the technical problems that the existing infrared camera device has many wire harnesses, theinstallation position is difficult to confirm, the infrared LED module generates heat and the camera size is large.

Description

technical field [0001] The invention relates to the technical field of vehicle cameras, in particular to a driver monitoring infrared camera device and an image brightness control method. Background technique [0002] According to the survey, 40% of the traffic accidents in China are caused by fatigue driving, and more than 30% of the traffic accidents are caused by distracted driving. In order to improve driving safety and reduce fatigue and distracted driving traffic accidents, the driver monitoring system has more and more applications in the field of safety assisted driving. [0003] For the driver monitoring technology, the driver monitoring technology generally uses the camera to capture the face state analysis technology. In order not to affect the normal driving of the driver, the driver monitoring system generally uses an infrared camera. In order to achieve normal work at night, it is necessary to add LED modules to supplement Light, the LED module light has a wav...
