Problems solved by technology

[0003] However, the camera monitoring equipment currently on the market cannot be used in daytime or in environments with dark light beams (such as tunnels, underground parking lots, etc.), so it cannot accurately capture the state of the driver and changes in the driving environment outside the cockpit , resulting in the inability to issue an accurate safety warning, thereby endangering the driver's life

Description

technical field [0001] The present application relates to the technical field of optical imaging, in particular to an optical system, an imaging device, electronic equipment and a carrier. Background technique [0002] With the development of society, the requirements for safety and monitoring in various fields are getting higher and higher, especially in the automotive industry, ADAS (Advanced Driving Assistance System, Advanced Driving Assistance System), DMS (Anti-fatigue warning system, Driver Monitor Status) , The application of CMS (Camera Monitor System, Camera Monitor System) in vehicle driving is gradually promoted. Not only is it required to monitor the driver's state, for example, the driver's state can be inferred from relevant information such as the driver's eye state, number of times of closing eyes, and number of yawns, but also requires monitoring and recognition of the driving environment outside the cab, so as to Comprehensively monitor the change of the ...
