| description | To recognize the inclination of a liquid level by the rotation of a rotator and inspect the height of the liquid level correctly.SOLUTION: A liquid level height inspection device images a liquid level of liquid inclined in a container 1 with the centrifugal force by the rotation of a rotator and recognizes the liquid level height of the liquid from a photographed image. Imaging means is provided on the inner side of a conveyance path of the container 1 to image an arcuate section A formed by the edge of the inclined liquid level. Image processing means comprises: a radius calculation unit which recognizes an approximate circle C for the arcuate section A and calculates a radius R of the approximate circle C; a temporary liquid level height calculation unit which calculates a temporary liquid level height from the arcuate section A; a correction value storage unit which stores the radius R of the approximate circle C and a correction value N measured by the experiment; and an actual liquid level height calculation unit which calculates the actual liquid level height H by using the radius R of the approximate circle C and the correction value N.SELECTED DRAWING: Figure 5
【課題】 回転体の回転による液面の傾斜を認識して、正確に液面の高さを検査することを目的とする。【解決手段】 回転体の回転による遠心力によって容器１の内部で傾斜した液体の液面を撮影し、撮影された画像から液体の液面高さを認識する液面高さ検査装置に関する。撮影手段を上記容器１の搬送経路の内側に設けて、傾斜した液面の縁部が形成する円弧状部Ａを撮影する。画像処理手段は、上記円弧状部Ａについての近似円Ｃを認識するとともに、当該近似円Ｃの半径Ｒを算出する半径算出部と、上記円弧状部Ａから仮液面高さを算出する仮液面高さ算出部と、上記近似円Ｃの半径Ｒと実験により測定した補正値Ｎを記憶する補正値記憶部と、上記近似円Ｃの半径Ｒと上記補正値Ｎとを用いて、実際の実液面高さＨを算出する実液面高さ算出部とを備える。【選択図】 図５ |
