Abstract
(EN)
Provided is a gas detection-use image processing device that comprises a processing unit 91, a determination unit 92, and an assessment unit 93. The processing unit 91 acquires a plurality of first images 1l by carrying out, on each of a plurality of infrared images captured at a plurality of different times, first processing for acquiring the first images 1l which are extracted from a prescribed region of the infrared images and which include a region image 1i showing a region in which a gas candidate appears. The determination unit 92 determines the movement direction of the region image 1i on the basis of two of the first images 1l, and taking into consideration that the region image 1i will move in the determined movement direction, the determination unit determines the similarity of the two first images 1l. The assessment unit 93 assesses whether the gas candidate is a gas on the basis of the similarity determined by the determination unit 92 and whether the region image 1i is moving.

L'invention concerne un dispositif de traitement d'image à usage de détection de gaz qui comprend une unité de traitement, une unité de détermination et une unité d'évaluation L'unité de traitement acquiert une pluralité de premières images par réalisation, sur chacune d'une pluralité d'images infrarouges capturées à une pluralité de moments différents, un premier traitement pour acquérir les premières images 1l qui sont extraites d'une région prescrite des images infrarouges et qui comprennent une image de région 1i montrant une région dans laquelle apparaît un candidat gazeux. L'unité de détermination 92 détermine la direction de déplacement de l'image de région 1i sur la base de deux des premières images 1l, et en prenant en considération que l'image de région 1i se déplacera dans la direction de mouvement déterminée, l'unité de détermination détermine la similarité des deux premières images 1l. L'unité d'évaluation évalue si le gaz candidat est un gaz sur la base de la similarité déterminée par l'unité de détermination et si l'image de région 1i est en mouvement.

ガス検知用画像処理装置は、処理部91と、決定部92と、判定部93と、を備える。処理部91は、赤外画像の所定領域から抽出された、ガス候補が出現している領域を示す領域像1iを含む第1の画像1Iを取得する第1の処理を、異なる複数の時刻で撮像された複数の赤外画像のそれぞれに関して実行し、複数の第1の画像1Iを取得する。決定部92は、2つの第1の画像1Iを基にして領域像1iの移動方向を決定するとともに、決定した移動方向へ領域像1iが移動することを考慮して、2つの第1の画像1Iの類似度を決定する。判定部93は、決定部92が決定した類似度、及び、領域像1iが移動しているか否かを基にして、ガス候補がガスか否かを判定する。
