Description

The present invention relates to a terrain measuring device and a terrain measuring method.

Conventionally, when reinforcing a slope where there is a risk of ground displacement such as landslides or landslides, a topographic map (three-dimensional topographic image) of the construction site is created in advance, but the topography is created in order to create this topographic map. As a device for measuring, a topographic map measuring device (hereinafter referred to as a conventional example) as disclosed in Patent Document 1 has been proposed.

In this conventional example, a measuring unit for measuring the terrain is provided on a flying object such as an aircraft or a drone, and the measuring unit measures the terrain while moving the flying object over the construction site. The measuring unit includes a device that measures the terrain by obtaining three-dimensional coordinates from a photograph taken by a camera, and a measuring unit that measures the terrain by irradiating a laser to obtain the three-dimensional coordinates.

Therefore, the conventional example is effective in measuring a wide range of terrain, as compared with the work of installing a measuring unit equipped with a tripod on the ground and measuring the terrain, which has been performed up to that point.

However, there are many mountainous areas in the construction site where these terrains are measured, and there is a problem that it is not possible to measure well if it is a conventional example of moving over the sky at a construction site where trees are vegetated or unevenness is severe.

In recent years, drones as flying objects are often used because of their ease of use, but crash accidents have become a problem, and the current situation is that they are strictly regulated year by year.
