AERIAL MARKING, ANALYSIS DEVICE, AND DRONE AIRBORNE SURVEY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an aerial marking, an image analysis device, and a drone airborne survey system, capable of accurately extracting or specifying a reference point from an aerial marking in a picked-up image and improving accuracy of the survey data to be generated.;SOLUTION: An aerial marking constitutes a drone airborne survey system 200 together with an analysis device. The analysis device comprises an input device which receives a position specification operation of an operator, a cursor display unit which displays a cursor on the picked-up image according to the position specification operation received by the input device, and a reference position setting unit which associates a position coordinate provided with an aerial marking 1 with a pixel of the indication point indicated by the cursor on the picked-up image. The aerial marking 1 comprises a reference point corresponding to the position coordinate indicating the installed position of the aerial marking, and a reference pattern which forms a shape similar to the shape of at least a part of the cursor of the analysis device.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
