The invention discloses an image acquisition device, a vehicle-mounted monitoring system and a vehicle, and the image acquisition device comprises a camera and a connecting piece which are connected with each other, the connecting piece comprises a power interface and a signal interface, the signal interface is used for transmitting a video signal to the camera, and the power interface is used for supplying power to the camera. Therefore, independent transmission of the direct-current voltage and the video signal is realized, a POC circuit does not need to be arranged in the camera, the size of a PCB of the camera is reduced, miniaturization is facilitated, attenuation and loss of the video signal caused by the POC circuit are avoided, and the quality of the video signal is improved; meanwhile, the requirement for current resistance of the coaxial line is lowered, manufacturing of the coaxial line is facilitated, the wiring difficulty of the PCB is lowered, and the stability of video signal transmission is improved.
本发明公开了一种图像采集装置、车载监控系统和车辆,其中,图像采集装置包括:包括相互连接的摄像头和连接件,连接件包括电源接口和信号接口,信号接口用于为摄像头传输视频信号,电源接口用于为摄像头供电。由此,实现了直流电压和视频信号的独立传输,从而不需要在摄像头中设置POC电路,减小了摄像头的PCB板尺寸,有利于小型化,且避免了因POC电路导致视频信号的衰减和损耗,使视频信号的质量提升;同时,降低了对同轴线的耐电流要求,有利于同轴线的制作,且降低了PCB板的布线难度,提高了视频信号传输的稳定性。
