For example, in the case of photogrammetry using a drone, the photographed picture must contain an identification mark that knows the exact location information of x, y, and z, which contains the altitude value. You will know the exact location.

However, the orthogonal images and survey data obtained as described above are position data obtained using a drone's GNSS (Globa Positioning System), which is more than 10m from the actual position.

In order to solve this problem, a ground control point (GCP) is installed in the area where the image is taken, and geographic information is corrected during data processing by measuring an accurate position value for the point.

The installation of the ground reference point involves selecting a location so that it is evenly distributed over the survey area, installing an identification sign that is recognized by the camera, and measuring the exact x and yz values of the identification mark with a precision surveying device. In addition, the manpower and time required for surveying and recovery may be more than twice the time for performing drone photogrammetry, which may lead to waste of manpower and budget.

As a prior art for solving this problem, Korean Patent Registration No. 10-1853348 (Announcement Date: April 30, 2018) discloses a method of setting a ground reference point using a drone, but a method of setting a ground reference point using a drone As a result, there was a problem limited to image observation using an RGB camera.

It is desirable to understand.

Among the accompanying drawings, FIG. 1 is a configuration diagram illustrating a drone for modifying geographic information with improved identification according to an embodiment of the present invention.

As shown in FIG. 1, the drone 100 for modifying geographic information according to an embodiment of the present invention includes a body 102 flying with a lift driven by a propeller and a hinge 104a provided in the body 102 It is configured to include a landing support device 106 provided in a foldable plate shape on the bottom surface of the main body 102, and an identification member 104 that is rotationally supported by and is changed to a folded or unfolded state. At this time, the landing support device 106 may be selectively applied.

In addition, the main body 102 is configured to include a sensor for posture control or position control, and controls posture control and propeller driving to match a control signal received from a remote location. For example, when the location of the object for surveying geographic information is a sea with severe waves, precise posture control is possible such that the main body 102 is positioned at a predetermined height above the water surface.

Among the accompanying drawings, FIG. 2 is a schematic cross-sectional view for explaining a state in which the identification member of the drone for modifying geographic information with improved identification shown in FIG. 1 is expanded, and FIG. 3 has improved identification according to an embodiment of the present invention It is an example showing that the identification member of the drone for modifying geographic information is folded and unfolded.

2 and 3, the identification member 104 maintains a folded state during the flight of the body 102 by the hinge 104a, and the body 102 is unfolded below a predetermined altitude or upon landing Constitutes the identification plate 104b.
