Linearis3D Software Development Kit

The Linearis3D Software algorithms are available as C++ and .net libraries and provide the following features:

• Fully automatic detection of ellipses with subpixel precision
• Detection of coded targets (Linearis3D and ring coded targets)
• Orientation of a single camera
• Multi-image photogrammetry
• High precision calibration of two cameras in a stereo setup
• Calibration of a single camera with different mathematical models
  • Distortion parameters according to Brown: radial-symmetric parameters A1, A2, A3 (on request also A4), radial-asymmetric and tangential distortion (B1, B2) as well as affinity and shear (C1, C2)
  • Extended calibration models for high end applications
  • Angle based calibration models for fish-eye lenses
