This paper describes a technique for measuring the volume of powder in a visual way. Powder has long been an important object of scientific research, since it has close relation with human life in various aspects. Yet lots of problems still remain to be solved.
The volume of a pile of powder whose shape is easily destroyed by a slight touch of an observer must be measured without any contact with it. This can be achieved by applying a three-dimensional shape reconstruction technique often employed in computer vision. We have developed a measurement system that finds the volume of powder piled on a table by employing a slit ray projection technique, and performed an experiment of determining the volume of PVC powder. The experimental result was satisfactory.
The proposed technique will be able to be applied to the estimation of the volume of fragile objects in general which need non-contact measurement.
