This invention relates to the technical field of concealed pipeline mapping, and in particular to an auxiliary device for rapid three-dimensional coordinate positioning of concealed pipelines in installation projects. The invention includes a mother drone equipped with a probe and camera mounted on it. A marking nozzle is connected to the mother drone, and the marking nozzle is connected to and installed on a daughter drone. The mother drone connects the marking nozzle and the daughter drone via a flexible hose and power cable. The device uses a mother drone integrating a probe and camera, enabling multi-angle, omnidirectional spatial scanning and image acquisition of concealed pipelines. This achieves rapid and accurate three-dimensional coordinate positioning of the concealed pipelines, significantly improving the accuracy and reliability of the positioning. The mother drone connects the marking nozzle and the daughter drone via a flexible hose and power cable, enabling remote synchronous control. The daughter drone can flexibly move to the pipeline positioning point and automatically complete on-site marking, avoiding errors associated with traditional manual line drawing and improving the accuracy and consistency of the marking.
