Vanishing Points, Parallel Lines, Grids
This chapter will discuss the properties of perspectively projected rectangular grids and some observations fundamental for their detection. These grids are typically the edges in images containing checkerboards, QR codes, and similar patterns. It will also analyze the contents of the parameter space that results from the Hough transform of such patterns.
