Self-calibration of stationary non-rotating zooming cameras

作者：

Highlights：

• A simple linear method to self-calibrate stationary zooming cameras

• Neither special camera motion nor scene knowledge required

• Two zoom images of a stationary camera provide two parallel principle planes.

• The plane at infinity can be located from two or more such zooming cameras.

• Simulation, laboratory and real scene experiments with 3D measurements validate our method.
