View topic - Ardupilot. Volume 1, Lecture 6. Considering that most aerial photographs are not perfectly vertical, there are three different photo centers: the principal point, the nadir, and the isocenter.

Volume 1, Lecture 6

Each one of these centers plays a specific role and is of great importance to the photogrammetrist because different types of distortion and displacement radiate from each of these points. Theoretically, if an aerial photograph is perfectly vertical, the three centers coincide at one point (i.e., the principal point), which is the geometric center of the photograph defined by the intersection of lines drawn between opposite fiducial marks (figure 6.6). The principal point is the optical or geometric center of the photograph.

It is the image of the intersection between the projection of the optical axis (i.e., the perpendicular to the center of the lens) and the ground (figure 6.6). The principal point is assumed to coincide with the intersection of the x and y axes. Geometry of Aerial Photography. I.

Geometry of Aerial Photography

Classification of Photographs In his book on aerial photo interpretation, Paine presents a dichotomous key for classifying aerial photography. The key is listed as follows: Photographs Terrestrial Aerial Vertical Oblique True Tilted High Low We can define vertical aerial photographs as a photo taken from an aerial platform (either moving or stationary) wherein the camera axis at the moment of exposure is truly vertical.

(Radial and coaxial) Advantages-Disadvantages? Hi everyone :) Althought it seems to me it's the first question that comes in mind when building a multirotor, there's not really much interest in determining which is the best design (deppending on the use) on the net.

I only could find some tri/quad comparation, but nothing comparing the CPU-balanced ones. Could you please tell me the main (relative) differences between them (including their possible layouts like raddial/coaxial).
