The invention discloses vehicle-mounted data acquisition equipment supporting bus data and video synchronization. The equipment comprises a bus data interface used for transmitting bus data, a cameramodule used for collecting video data, a GPS module used for sending a clock signal, an ignition trigger power supply used for supplying power to a bus collection module, the bus collection module anda video collection module. The bus acquisition module is used for sending a synchronous response time signal to the video acquisition module, and introducing a time synchronization compensation amount when bus data and video data are received, so the acquired bus data and video data are synchronized in time; the video acquisition module is used for receiving a clock signal, sending the clock signal to the bus acquisition module, receiving a time signal sent by the bus acquisition module, determining a time synchronization compensation amount, and sending video data and the time synchronization compensation amount to the bus acquisition module. According to the invention, synchronous acquisition between different buses and videos can be realized, so high-quality scene information is provided for developers, and the development efficiency is improved.
