METHOD OF INVESTIGATING STATIONARY GAS DETECTION DEVICE INSTALLATION SITE

摘要

To prevent, when a non-image type gas detection device is used as a stationary gas detection device, the stationary gas detection device from allowing that there exists any place where gas might leak.SOLUTION: A method of investigating a stationary gas detection device installation site comprises: a first step of capturing, for a predetermined first period, infrared images of a predetermined region 31 where gas leakage is predicted in a monitor area 30, and executing image-based gas detection using the infrared images captured for the period; a second step of executing a learning phase of machine learning with, as teacher data, abnormal images (gas images and images of abnormal temperature positions) extracted from the infrared images by executing the first step, such that a learning model 16 for recognition of abnormal images is bui a third step of capturing infrared images in the monitor area for a predetermined second period; and a fourth step of performing, using the learning model 16, a recognition phase of the machine learning on the infrared images captured in the third step.SELECTED DRAWING: Figure 2
