英文摘要 | This paper describes a novel velocimetry method we call infrared quantitative image ve1ocimetry (IR-QIV), that uses infrared (IR) images of thermal patterns advecting on water surfaces to calculate time-resolved, instantaneous, two-dimensional surface velocity fields. The method works day or night, and under most weather conditions, by tracking subtle thermal patterns on the water surface itself, which are present under most environmental conditions. No particle ’seeding’, external light sources, or contact with the water are required. A form of remote sensing, IR-QIV has significant advantages over visible-light surface velocimetry methods such as particle image velocimetry (PIV). IR-QIV allows calculation of instantaneous velocity at high spatial (centimeter scale) and temporal ( |
