Abstract

Insufficient spatial resolution is a common problem in aerial imaging. An approach for spatial resolution enhancement using several images of low spatial resolution with relative subpixel displacement for the superresolution is proposed. Demo example of superresolution of test aerial image acquired by 4K camera onboard DJI Phantom 4 quadcopter is described.
