MEASUREMENTS OF FALLING ATTITUDES OF SNOWFLAKES USING TWO VIDEO CAMERAS

Falling attitudes of snowflakes were simultaneously photographed by two video cameras from horizontal and vertical directions, and these images were analyzed by an image processor and personal computer. The attitude of each snowflake was measured every 1/30s from its two images. It is generally foun...

Description
Summary:Falling attitudes of snowflakes were simultaneously photographed by two video cameras from horizontal and vertical directions, and these images were analyzed by an image processor and personal computer. The attitude of each snowflake was measured every 1/30s from its two images. It is generally found that snowflake images from the top are larger than the ones from the side and some snowflakes rotate during fall.
