Title
(EN) GAS LEAK LOCATION ESTIMATING DEVICE, GAS LEAK LOCATION ESTIMATING SYSTEM, GAS LEAK LOCATION ESTIMATING METHOD AND GAS LEAK LOCATION ESTIMATING PROGRAM
Abstract
(EN)

A gas leak location estimating device includes: an information processor which acquires image information on a plurality of frames from an infrared camera, the information processor being capable of executing: a block discrimination processing of dividing an image area of each of the frames into a plurality of blocks and discriminating whether each of the blocks is a gas area; a count processing of counting a number of times each of the blocks is discriminated as the gas area, over the frames in chronological order, in the block discrimination processing; and a leak location estimation processing of setting, among the blocks, a block whose counted value obtained in the count processing is equal to or larger than a predetermined value as an estimated gas leak location.
