[0002] Surveying and mapping refers to the measurement, collection and drawing of the shape, size, spatial position and attributes of natural geographical elements or artificial facilities on the surface. With the growing demand for spatial data in all walks of life in the information age, conventional data acquisition methods and data processing modes are increasingly unable to meet the needs of informatization. More and more surveying and mapping instruments and sensors are used to acquire spatial data: such as total stations, GPS, 3D laser scanning equipment, photogrammetry equipment, etc., which use the acquired spatial data to draw two-dimensional drawings or build three-dimensional models. This series of work can be completed by one device or multiple devices. There are many surveying and mapping environments that are inaccessible to workers or are dangerous. Measurement through remote-controlled mobile platforms has undoubtedly brought great convenience.
