Gauge-based variable-lighting
photometric stereo

Statement of problem

• Recover the third dimension (height/depth) of a scene given a list of images of the same, taken from the same viewpoint with different illuminations.

Aims and methods

• Use calibration objects (light gauges) to sample the light field.
• Develop protocols for accurate calibration and alignment of images.
• Develop fast and robust algorithms for light-to-normal computation.
• Develop fast and reliable slope-to-height integration.
