Title: GAS MEASUREMENT SYSTEM AND GAS MEASUREMENT PROGRAM
Abstract:
In order to automatically determine measurement conditions to achieve stability of measurement even when there is variation in the installation of a gas measurement device, and thereby to facilitate installation operations, this gas measurement system is provided with: a portable gas measurement device (10) which scans a laser to acquire two-dimensional gas distribution information; an imaging means (15, 40) which captures an image of a measurement candidate area around the position where the gas measurement device was installed; an image feature extraction means (20, 40) which extracts features from an image captured by the imaging means; and a measurement condition setting means (20, 40). On the basis of differences in features between a reference image captured of the measurement area and a captured image of the present measurement, the measurement condition setting means sets a measurement area and measurement sampling density for the present measurement so as to reduce the differences of the measurement area and the measurement sampling density between a previous reference measurement and the present measurement.
