Half-sweep imaging for depth from defocus

作者:

Highlights:

• We propose a novel imaging approach, “Half-sweep imaging”, for depth from defocus.

• Novel PSF engineering by focus changes during each exposure time.

• Complementary responses of the PSFs help image restoration and depth estimation.

• Increasing the quantity of the incident light affects the quality of DFD estimation.

• We built the prototype camera and confirmed the effectiveness of our approach.
