Description

technical field [0001] The invention relates to the technical field of geotechnical engineering survey, in particular to an engineering survey drone system based on satellite positioning and navigation and a survey and mapping method. Background technique [0002] In geotechnical engineering surveys, especially in industrial and civil construction surveys, drilling sampling and in-situ testing are still the most mainstream survey methods. At this stage, the working mode of geotechnical engineering survey field is still relatively primitive. In terms of measurement and setting out, drilling, sampling, in-situ testing, cataloging, sampling, etc., manual operation and handling are still the main methods. [0003] In terms of drilling survey and stakeout, technicians need to design the drilling plane position map in advance, and arrange surveyors to stake out and mark. During the construction process, the drilling rig personnel need to find the drilling marks by themselves, a...

Problems solved by technology

[0005] Some patents on the use of UAVs for surveying, surveying, mapping, field management and sampling have appeared in my country, but most of the functions of these patents only stay in relatively simple aerial photography, sampling, etc.

They are still lacking in surveying and setting out, transporting materials, sampling, flight control, field human-computer interaction management, text recognition, lost and retrieved, etc., resulting in the application of UAVs in geotechnical engineering surveys to stay in the imagination and difficult to implement
