Problems solved by technology
[0003] In the prior art, unmanned aerial vehicles can be used to fly into the air to measure the elevation, but factors such as wind force in the air make the unmanned aerial vehicle not always maintain a level, which makes it easy for the measurement equipment on the unmanned aerial vehicle to measure the height that is not perpendicular to the ground. Height; Secondly, in the prior art, the remote control car can be used to drive to the required position for horizontal measurement. Due to the unevenness of the terrain, the remote control car is easy to tilt, so that the measurement equipment on the remote control car is not parallel. The distance from the ground, so the measurement error is large

The invention discloses a three-dimensional terrain surveying and mapping system, specifically relates to the technical field of surveying and mapping, including a drone and a remote control car, the remote control car is arranged under the drone, and a housing is arranged between the drone and the remote control car , one side of the housing is provided with a connecting rod, one end of the connecting rod extends into the housing and the other end is provided with a cover, the top of the inside of the cover is fixed with a first laser scanner, and the inside of the cover is A first induction mechanism is provided, a first adjustment mechanism is provided on one side of the housing, a second adjustment mechanism is provided inside the other end of the connecting rod, and a second laser scanner is provided on the front side of the remote control car. A third adjustment mechanism is provided on the rear side of the second laser scanner. In the present invention, the first laser scanner emits vertical laser pulses to measure the elevation through the first adjustment mechanism and the second adjustment mechanism, and the second laser scanner emits horizontal laser pulses to measure the level of the target object through the third adjustment mechanism. coordinates, the measurement error is small.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of surveying and mapping, and in particular to a three-dimensional terrain surveying and mapping system. Background technique [0002] Surveying and mapping refers to the measurement, collection and drawing of the shape, size, spatial location and attributes of natural geographical elements or surface artificial facilities. Three-dimensional topographic mapping is the measurement of terrain in three-dimensional directions, including plane coordinates and elevation. The three-level laser imaging system is one of the commonly used measurement methods. The laser pulse is emitted by the laser scanner, and the time delay from the emission of the laser pulse to the reception of the target object is recorded and multiplied by the speed of light. The emission point to the reflection point can be accurately measured. distance. [0003] In the prior art, unmanned aerial vehicles can be used to ...
