Description

technical field [0001] The invention belongs to the field of coalfield geological exploration instruments, and in particular relates to a multi-source sensor scanning device and a construction method for a mining portable roadway, which can be used for rapid scanning of underground roadways in coal mines and provide data support for high-precision geological model construction. Background technique [0002] Coal mine roadway is the artery of mine production. It is responsible for underground mining, transportation, ventilation, drainage and other tasks, which directly affects the economic benefits and production safety of coal mine production. The establishment of a true three-dimensional roadway model can guide the mining design plan, engineering construction and safety. Rescue, etc. are of great significance. [0003] The core link of 3D modeling and reconstruction of the roadway is the basic data, and the foundation comes from the roadway measurement. According to the min...

Problems solved by technology

[0004] In the known technology, the traditional way of manually measuring the roadway and modeling has the disadvantages of difficult data acquisition, long modeling period, and low model accuracy; most wheeled mobile robot platforms adopt an integrated structure design, and in roadways with complex working conditions It is difficult to navigate by itself, the data collection information is not comprehensive, and the point cloud data splicing is difficult; the flexible track mobile robot platform only has incomplete data information collected by laser radar, inertial measurement unit, and odometer, and the installation and maintenance are inconvenient. Can move in a fixed area, it is difficult to meet people's needs
