The invention discloses an earthwork amount detection system based on laser radar data acquisition, and the system comprises a system working platform, an airborne laser radar, a high-precision positioning and attitude determination system POS, a suspension rack, and an RTK base station. The system working platform carries the airborne laser radar to scan and map a planned earthwork area; and the RTK base station acquires real-time dynamic high-precision point cloud data, synchronously receives satellite information, acquires base station data, and performs differential calculation in combination with radar data acquired by the airborne laser radar and POS data acquired by the high-precision positioning and attitude determination system POS so as to realize accurate positioning of the point cloud data. The distance between the airborne laser radar and the carrying unmanned aerial vehicle can be adjusted through the arranged suspension rack, so that sufficient mounting space is reserved below the system working platform, the inclination angle of the airborne laser radar in the initial state is conveniently adjusted, and vibration occurring in the flight process of the system working platform is relieved; and the data acquired by the airborne laser radar is more stable and accurate.
