Abstract

The present invention discloses a three-dimensional topographic survey system and method. The system comprises a floating hosting platform, a detection device and a ground device. The floating hosting platform is located in the stratosphere on a preset ground area to be surveyed, the detection device is arranged on the floating hosting platform and configured to survey the preset ground area according to the survey instruction information sent by the ground device and return the survey data back to the ground device; and the ground device processes the returned survey data to obtain DEM data. According to the three-dimensional topographic survey system provided by the embodiment of the invention, the detection device is arranged on the floating hosting platform to survey the preset ground area and cooperate with the ground device to solve the survey data so as to realize the effective and accurate survey of the three-dimensional DEM data and solve the problems that the survey precision and the survey efficiency are low when a remote control aircraft is employed to perform three-dimensional DEM data survey in the prior art.

Description

Technical field [0001] The invention relates to the technical field of surveying and mapping, and in particular to a three-dimensional topographic surveying and mapping system and a surveying and mapping method. Background technique [0002] With the rapid development of science and technology, human activities have increasingly higher requirements for map accuracy and update rate, ranging from life and travel, factory buildings, to urban planning, military surveying and mapping, and high-precision three-dimensional digital elevation models (Digital Elevation Model, (Referred to as DEM) data acquisition has become a hot spot in the field of surveying and mapping. For the acquisition of 3D DEM data, ground manual surveying and mapping is the most primitive and effective method, which can obtain the most accurate and high-resolution surveying and mapping data. However, ground manual surveying and mapping also has its shortcomings: low efficiency, consuming a lot of manpower and tim...
