GAS MIGRATION ESTIMATION DEVICE, GAS MIGRATION ESTIMATION METHOD, ESTIMATION MODEL GENERATION DEVICE, ESTIMATION MODEL GENERATION METHOD, AND PROGRAM

摘要

[Problem] To provide an estimation device and estimation method whereby it can be detected whether gas is flowing in a near-far direction with respect to a viewpoint, even if gas monitoring is performed on the basis of only images from a single viewpoint. [Solution] A gas migration estimation device comprising: an image input unit that receives, as input, a gas distribution video in which a range, in which gas that has leaked into a space is present, is displayed as a gas zone; and a gas migration estimation unit that uses an estimation model which was machine-learned using, as training data, combinations of gas distribution videos for training and the states of gas migration in the near-far direction in the data gas distribution videos for training to thereby estimate the state of gas migration in the near-far direction corresponding to a gas distribution video received by the image acquisition unit.
