Introduction

Zihan Liu is an inventor based in Beijing, China, and is associated with China Agricultural University. His patent work addresses channel-flow measurement using computer vision and a method inspired by bionic eagle-eye vision.

Latest Patents

Liu is named on 1 patent: “Method for Measuring Channel Flow Based on Bionic Eagle-Eye Vision and Apparatus Thereof.” The invention describes acquiring video of flowing water in a channel and extracting image frames for observation. It calculates optical flow and uses changes in image position, together with spatial resolution, to estimate surface-flow velocity in world coordinates. A pre-trained model then relates surface velocity to average cross-section flow velocity, which is combined with the water level at the cross-section to calculate channel flow.

Career Highlights

The patent reflects an approach to flow measurement that combines video analysis, optical-flow calculations, and a trained coupling model. The provided information identifies Liu’s affiliation with China Agricultural University but does not specify his role or other career details.
