The embodiment of the invention provides a vehicle-mounted camera, a motor vehicle video acquisition system and a motor vehicle video acquisition method. The vehicle-mounted camera is connected with avehicle-mounted multimedia device and is composed of the following modules: a video acquisition module used for acquiring video images around a motor vehicle in real time and converting the video images into video digital signals; a serial communication module directly connected with the vehicle-mounted multimedia device through a wire harness to establish serial communication connection, and used for performing serialization processing on the video digital signals to form serialized video signals and then sending the serialized video signals to the vehicle-mounted multimedia device; and a power supply module used for supplying power to the video acquisition module and the serial communication module. According to the embodiment of the invention, the vehicle-mounted camera does not carryout storage, image processing and encoding on video data, so that the overall vehicle-mounted camera occupies a smaller volume. Only the video digital signals are sent to the vehicle-mounted multimedia device after being subjected to serialization processing, the number and the size of transmission wire harnesses are reduced, and the cost of the wire harnesses is reduced.
本发明实施例提供一种车载摄像头、机动车视频采集系统及机动车视频采集方法,所述车载摄像头与车载多媒体装置相连,由以下模块构成:视频采集模块,用于实时采集机动车周围的视频影像并将视频影像转化为视频数字信号;串行通信模块,通过线束直接与车载多媒体装置相连建立串行通讯连接,用于将视频数字信号进行串化处理形成串化视频信号后再发送给车载多媒体装置;电源模块,用于为视频采集模块和串行通信模块供电。本实施例车载摄像头不对视频数据进行存储、图像处理和编码,整体车载摄像头占用体积更小;仅对视频数字信号进行串化处理后即发送给车载多媒体装置,减小传输线束的数量和尺寸,降低了线束的成本。
