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
