Abstract

This paper describes a novel method for mobile-vibration-based crop inspection to visualize differences in dynamics between vibrating crops and objects pixel by pixel with vision-based FFT analysis. High-frame-rate video analysis was conducted for (1) multiple fans and (2) rice grains and husks on a vibrating sieve, and they were verified by enhancing the differences in dynamics between multiple objects even when their appearances are too similar to distinguish each other in a single image.
