perspective

If I take a photo of an object from two different points of view, how can I compare the relative angle of the object to another object within both pictures? For example, if took a photo of railroad tracks while standing on the ground, the angle of one track to the other will appear to be greater than zero degrees. However, if I take the picture from a hot air balloon the tracks will appear to be parallel. Is there a way to show mathematically that the tracks did not move and that they were always the same angle relative to each other? Thanks for any help.

Conclusions drawn from two monoscopic images taken at different perspectives will be far more accurate than conclusions drawn from one monoscopic image. The bulk of the maths required within any of the algorithms used will for the most part be limited to simple trigonometry. Linear transformations and transformation matrices are a great asset to any software development that involves graphical details or object/world transformation.

 

Compiling the information withing a monoscopic image is a detailed process despite the relatively simple maths. Compiling a solution to this problem is intensive and requires that a number of approaches to several problems be facilitated. Comparisons of several points of reference, within identifiable objects, need to be made with respect to light sources and scaling.
