Vehicle-interior monitoring device and method based on single camera

Abstract

The invention discloses a vehicle-interior monitoring device and method based on a single camera. The vehicle-interior monitoring device comprises a vehicle body control unit, further comprises a camera control unit, an engine unit, a combined instrument unit, a vehicle-mounted T-BOX unit, a braking pedal sensor, a one-key starting switch, a vehicle-speed sensor, a safety belt lock catch switch and a vehicle window lifting motor which are connected with the vehicle body control unit, and further comprises the camera connected with the camera control unit. The camera has diversified shooting modes. The vehicle body control unit judges the scenes where a vehicle is located at current according to the states of the engine unit, the braking pedal sensor and the vehicle-speed sensor, the different shooting modes and angle adjusting instructions are sent to the camera control unit according to the difference of the scenes where the vehicle is located, and the camera control unit controls thecamera to conduct switching of the shooting modes and adjusting of the angles. According to the vehicle-interior monitoring device and method based on the single camera, only through one camera, thediversified functions such as vehicle owner identification, safety belt unfastening detection and passenger trapping calling for help can be achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile electrical appliances, and in particular relates to an in-vehicle monitoring device and method based on a single camera. Background technique [0002] At present, with the development of car camera technology, car cameras are widely used in cars to improve driving safety and intelligent humanization, such as 360° panoramic images, reversing images, driving recorders, face recognition, gesture control, etc. [0003] In order to realize many functions, a car needs to install multiple cameras, but each camera has only one shooting mode and one fixed shooting angle, and can only realize a single function. For OEMs, it not only increases the cost of the vehicle, but also increases the difficulty of vehicle layout and design; for ordinary consumers, it undoubtedly increases the cost of car purchase and subsequent maintenance and repair costs. [0004] Therefore, it is necessary to develop an in-vehi...
