GAS MONITORING METHOD, GAS MONITORING DEVICE, GAS MONITORING SYSTEM, AND GAS MONITORING PROGRAM

Abstract: a gas monitoring method includes: acquiring a plurality of velocity vectors obtained by performing optical flow estimation processing on a plurality of pieces of image data obtained by imaging at a plurality of times with an imaging device mounted on a uav; acquiring a downwash velocity u of the uav based on at least one variable indicating a flight state of the uav; and extracting a gas velocity vector having a magnitude within a range determined based on the downwash velocity u from the plurality of velocity vectors.
