Description

Technical Field

[0001] The invention relates to the field of surveying and mapping technology, in particular to a device for surveying and mapping forest land topography. Background Art

[0002] Surveying and mapping is the process of measuring and drawing. Based on computer technology, optoelectronic technology, network communication technology, space science, and information science, with global navigation satellite positioning system, remote sensing, and geographic information system as the core technology, the existing characteristic points and boundaries on the ground are measured to obtain graphics and location information reflecting the current situation of the ground for the planning, design, and administrative management of engineering construction. Surveying and mapping methods include ordinary measurement and photogrammetry.

[0003] During the surveying process in wooded areas, the ground is mostly soil and the slope is inclined, which is not conducive to the stable placement of ground equipment. Therefore, aerial drones are usually used for topographic mapping operations to improve the efficiency and convenience of surveying. However, this type of drone has the following problems: since data transmission depends on the communication module of the drone, as the distance increases, the signal strength of the drone decreases, making it impossible for personnel to stably receive data or control the drone. At the same time, since the drone needs to carry additional surveying equipment, this will increase the load of the drone, reducing the endurance of the drone under limited power, shortening the surveying time, and is not conducive to long-term surveying operations in the air.
