  • Page 27: Warping Algorithms

    6.1 Warping algorithms The FUSION processing system supports 3 different warping algorithms: Perspective, Mesh Warp Transform, Mesh Warp Bezier. The best way to understand how they work is to test the different algorithms in an actual system setup.

  • Page 28: Warping User Interface

    Increasing grid size during calibration is very convenient. This enable for rough calibration with few control points, and fine tuning with increased grid size as needed. Decreasing grid size during calibration is not recommended as you may lose fine tuning data you have already added to the grid. FUSION – Geometry correction...

  • Page 29: Scaling Filters

    6.3.2 B-spline filter The B-spline filter available in the FUSION processing system is of the type Cubic B-spline. This filter is slightly softer than the Lanczos filter, but has better quality on curved and straight lines.

  • Page 31: Working With The Mesh Transform Algorithm

    6.5 Working with the Mesh Transform algorithm To start working with Mesh Transform algorithm, click the “Warp” icon, add the Mesh Transform algorithm and start with setting the grid size to 1x1. First map the four corners to their desired location. As required, increase the grid size. This will add more rows, columns and control points to the mesh and enable the possibility to map the grid correctly onto the surface.

  • Page 32: Working With Mesh Bezier Algorithm

    Like with the Mesh Transform algorithms, the grid size can be increased as much as needed to get the required accuracy for a given surface. A 1x1 grid should regardless of the projection surface be used as a starting point. FUSION – Geometry correction...
