CPC F23G 5/027 (2013.01) [F23G 5/16 (2013.01); F23G 5/24 (2013.01); F23G 5/50 (2013.01); F23G 2201/40 (2013.01); G01F 23/292 (2013.01); G06T 7/90 (2017.01)] | 5 Claims |
1. A gas swirling state determination system for determining quality of a swirling state of gas swirling around a central axis, the system comprising:
an imaging device configured to capture the swirling gas from a direction along the central axis to acquire still images;
an information processing device including a calculation unit configured to calculate luminance distribution information for each of the plurality of still images captured at different times by the imaging device to acquire a swirling speed of a centroid of the luminance or a luminance difference at a specific location of the still image as a first calculation result, a smoothing unit configured to smooth a change in the first calculation result over time to acquire a second calculation result, and a determination unit configured to compare the second calculation result with a threshold and determine the quality of the swirling state to acquire a determination result; and
a display device configured to display the determination result.
