| Abstract: |
(EN) The dust concentration in, e.g., a tunnel is simply measured by means of a portable imager. When the space in a tunnel is imaged by using a strobe of a digital camera, the flash from the strobe is reflected by particles floating in the air. The reflected light is captured and a white-spot image is captured. By counting the white spots, the dust concentration can be estimated. The dust measuring device comprises image extracting means for extracting white spots in an image, area calculating means for calculating the area of the white spots of the image, comparing means for judging whether or not the value calculated by the area calculating means is within a preset region, means for counting the number of the white spots in the preset region, and display means for displaying the count result. (JA) 携帯可能な撮影装置を使用して簡単にトンネル内等の粉塵濃度を測定できるようにするものであって、トンネル内においてデジタルカメラのストロボを使用して空間を撮影すると、空間に浮遊する微粒子にストロボからの閃光が反射し、反射光が白斑画像として撮影される。この白斑の数をカウントすることによって粉塵濃度を推定することが可能となる。粉塵測定装置は、画像中の白斑を抽出する画像抽出手段、白斑画像の面積を計算する面積計算手段、及び面積計算手段で得られた数値が設定範囲内にあるかを判定する比較手段、設定範囲内の白斑画像の数をカウントする手段、及びカウント結果を表示する表示手段とからなる。 | ||||||||||||||||||
