Simplified Active Calibration

作者：

Highlights：

• We propose a closed-form camera calibration: Simplified Active Calibration (SAC).

• SAC uses only three pairs of images captured by active camera movements.

• SAC can estimate focal length using only one point correspondence.

• SAC utilizes the degenerate motion of a camera to estimate parameters.

• SAC eliminates the need for using known patterns or wands.
