CALCULATION OF GPS COORDINATES OF OBJECTS DETECTED FROM AERIAL PHOTOGRAPHY
https://doi.org/10.26583/vestnik.2023.249
Abstract
This article discusses an algorithm that allows you to calculate the GPS coordinates of an object detected in images taken from an unmanned aerial vehicle (quadcopter). The developed algorithm can be used in the tasks of detecting various objects and then plotting their coordinates on maps. The authors of the article describe an approach to solving this problem, identify the main stages of the algorithm. An approach to writing a program implemented in the C++ programming language using the OpenCV open source library (machine vision library) is described. The results of the program are demonstrated. The authors managed to achieve the accuracy of calculating the GPS coordinates of objects of the order of one meter, which is comparable to the accuracy of satellite positioning of a quadcopter from which aerial photography of the underlying surface is carried out.
