Root Cause

Perspective transform received invalid or collinear points.

generic

Workarounds

  1. 90% success Ensure 4 non-collinear points in correct order (TL, TR, BR, BL)
  2. 88% success Validate points form a convex quadrilateral before transformation

Dead Ends

Common approaches that don't work:

  1. Use affine transform as fallback 68% fail

    Only 3-point mapping

  2. Add random jitter to points 72% fail

    Inaccurate transform
