초록

A volume measurement system uses volume element counting in determining the amount of a liquid such as fuel in an irregularly-shaped container such as a fuel tank which can have changing orientation. The container is conceptually divided up into a plurality of volume elements. An orientation sensor determines the orientation of the container or of the liquid surface, which is approximated as a plane. A computational or optical processor uses orientation data to project vectors representing the volume elements onto a direction normal to the liquid interfa...
