elements of external orientation

Development of a methodics for improving the accuracy of determination of spatial coordinates of object points during air surveillance from a UAV

Purpose.  Develop an optimal algorithm that will increase the accuracy of determining the coordinates of the terrain when using the aerial process applying an unmanned aerial vehicle (UAV). Method. The minimization of function based on the condition of collinearity is performed, which clarifies the elements of external orientation (EZO) of digital images and leads to an increase in the accuracy of the spatial coordinates of the points of objects.
