LAMINAR FLOW SMOKE DETECTION DEVICE AND LAMINAR FLOW SMOKE DETECTION METHOD

摘要

PROBLEM TO BE SOLVED: To suppress an affection of a false report source, and to improve detection accuracy.SOLUTION: A laminar flow smoke detection device comprises: a laminar flow smoke generation part (32) for determining that there is a laminar flow smoke in a monitor object image, when a Mahalanobis distance calculated with respect to distribution of a laminar flow smoke feature amount histogram has a value within a first predetermined range, and a Mahalanobis distance calculated with respect to distribution of a false report source feature amount histogram has a value out of a second predetermined range, about a relationship of the feature amounts which are calculated about the monitor object image by a feature amount extract part (20).
