Edit: Issue #58, has already pointed out this first problem. Figure 41.6 uses x' and y' on both side of the equation. One of the sides should use x and y instead to differentiate between the two screen space points.
Also, in the equation right below 41.6 that relates corresponding points with a homography H, the place of the [x, y, 1] and [x', y', 1] appear to arbitrarily switch from figure (41.5). This seems unnecessary and could cause confusion
