Gas leak position estimation device, gas leak position estimation system, gas leak position estimation method, and gas leak position estimation program

摘要

It is an object to accurately estimate the gas leak position. The gas leak position estimation system (100) includes an infrared camera (10) that includes an object to be monitored in an imaging range, and information processing means (30) that acquires image information from the infrared camera over a plurality of frames. The information processing means divides the image area into a plurality of blocks for each frame, and performs a block determination process for determining whether each block is a gas area, and a block determination process for a plurality of time-series frames. A count process for counting the number of times determined as an area for each block and a leak position estimation process for setting a block whose count value by the count process is a predetermined value or more as a gas leak estimation position can be executed. For example, a block B0611... Having a count value of 9 or more is set as the estimated gas leak position.
