Unsupervised Vanishing Point Detection and Camera Calibration from a Single Manhattan Image with Radial Distortion
- Plucker coordinates for 3D line computations.
- LCC = line of circle center, bisector of the chord.
- Circle fitting: second moment matrix, scattering ellipse
- centroid of the chord determined from the scattering ellipse
- angle between the LCC and the x-axis is determined.
- fix the fast marching with dealing with negative sign.
