ProcessesCalibration Tsai’s method, with planar object To calibrate the projector we need to know what it
sees (backward projection)
Correspondence Analysis Find camera-projector pixel-wise mapping By Applying pattern codification methods
TriangulationMesh Conversion Convert depth map to triangles
Registration Combine meshes from different views
ComponentsCanon EOS 1000D Very high resolution, up to 3888 x 2592 Need to have it controlled by program SDK acquired
Projector Effective resolution: 1024 x 768
Tripods For flexibility in hardware configuration
PC or Laptop Fast enough to process shots in real-time
