«Relative orientation of the aerial views with the new combination of the corner piece within the stereo mate»
Incoming article date: 29.04.2014Relative orientation of the aerial views is the fundamental task of the photogrammetry. The final results depends on the accuracy and reliability of its solving, characterizing the spatial position of the photographed object (area).
Two groups of the elements of the relative orientation found their industrial application in our country (then ERO). However they don’t use up all the possible combinations of the corner pieces res ipsa loquitur and also between the photogrammes. Moreover it is known that in both systems of the relative orientation of the aerial views (base and linear-angular) visible correlation of the mistakes of the ERO are found, which leads to the additional of the route trough model within the coordinate space XY and XZ.
One of the possible alternative variants of the application within the group ERO of another corner piece is examined in this article. Five elements of the relative orientation of the aerial views are presented on the left view of the stereo mate as two angles: transverse inclination angle ω1 and longitudinal slope α1, and two angles (α1 and χ2) on the right and the azimuth of the direction of the basis of the design τ. Such a diviosn of the ERO has reduced much the correlation between the mistakes of the angle elements. However other variants are possible (e.g., τ, υ, χ1, α2 and ω2).
To calculate the photogrammetry co-ordinates of the general formula of the straight photogrammetry mark is proposed, which can be used both for the aerial shots in any direction and for the shooting from the points of the earth surface.
