Abstract
In order to clarify the process of formation and its differences by weather conditions of snowflakes, it is necessary to measure and analyze the shapes of snowflakes. This paper describes a measuring system for getting two-dimensional image data using three CCD cameras mounted in different locations. In addition, 2D-Video-Distrometer (" 2DVD" ), the raindrop analyzer, was used for automatic data acquisition. By line scanning, it can get data such as drop size distribution, terminal velocity, oblateness, and silhouette image of snowflakes. We present the method for producing the three-dimensional image of snowflakes by image processing.
