Problems solved by technology
[0005] With the development of satellite remote sensing technology and camera lens technology, remote sensing satellites can clearly take images of ground targets, but most of the images taken are planar due to the angle of view, which has little reference value for mountains and hills. Although the technology Personnel can survey and restore the 3D map of the mountain through the multi-view view of the mountain, but the surveying and mapping effect is poor

The invention discloses an information acquisition device and information acquisition method for geographic surveying and mapping, and belongs to the field of geographic surveying and mapping devices.According to the information acquisition device and information acquisition method for the geographic surveying and mapping, an unmanned aerial vehicle drops multiple information acquisition devicesfrom air, the altitude of the local position of a mountain is accurately measured through cooperation of the multiple information acquisition devices, a specific three-dimensional stereogram of a surveying and mapping area is generated through technologies such as remote sensing satellites and the like, the surveying and mapping precision is improved, in the air-drop process of the information acquisition devices, when a buffer plate makes contact with the mountain, impact generated by collision compresses a compression spring, an anchoring end penetrates through a through hole in the buffer plate to be anchored to the mountain, the compression spring can greatly reduce hard impact generated by collision between the buffer plate and the mountain, the probability that a sensor terminal carried on a fixing base is damaged is reduced, and therefore, the whole information acquisition devices can be firmly fixed on the mountain for measurement.
Description
technical field [0001] The invention relates to the field of geographic surveying and mapping devices, and more specifically, to an information collection device and collection method for geographic surveying and mapping. Background technique [0002] Surveying and mapping is literally understood as surveying and drawing. It is based on computer technology, photoelectric technology, network communication technology, space science, and information science. It is based on global navigation satellite positioning system (GNSS), remote sensing (RS), and geographic information system (GIS). The technical core is to select the existing feature points and boundaries on the ground and obtain the graphics and position information reflecting the current situation of the ground through measurement means for engineering construction, planning and design and administrative management. [0003] Surveying and mapping research measures and calculates the geometric position of ground points, ...
