The invention discloses a vehicle-mounted infrared camera system which comprises an image sensor module, an image processor module, a serializer module, a power management module, a band elimination filter module and an infrared LED module. The image sensor module is connected with the image processor module. The image processor module outputs an image signal to the input end of the serializer module. An output end of the serializer module outputs a video serial signal to the band elimination filter module, and the band elimination filter module transmits the video serial signal to an externalmain controller through a coaxial cable. The image sensor module outputs a pulse signal to the infrared LED module. Before exposure, the image sensor module sends a pulse signal to the infrared LED module, the infrared LED module is turned on for a period of time to supplement light according to the pulse signal, and the infrared LED module is turned off after exposure is completed. LED only works when the image sensor needs to be exposed, so that power consumption is reduced, and size is reduced. The scheme is suitable for in-vehicle image acquisition.
Description
technical field [0001] The invention relates to the technical field of vehicle-mounted cameras, in particular to a vehicle-mounted infrared camera system used for in-vehicle image acquisition. Background technique [0002] With the continuous progress and development of science and technology, safe driving and intelligent driving have become areas that people pay close attention to and constantly introduce new ones. As a complete intelligent control system, whether it is an assisted driving system or an automatic driving field, the on-board high-definition camera has become an indispensable and extremely important sensor device in these systems. As an important means of in-cabin detection, the infrared camera autonomously emits near-infrared short-wave invisible light to the outside world to provide an auxiliary exposure light source for the image sensor to obtain image information. It reaches the camera image sensor to realize the real-time detection of the cabin situation...
