Sample paper for 7WCSCM

摘要：

　　This study proposed a non-intrusive and cost-efficient technique to measure the thickness of water film/rivulets based on grayscale index.It has millions of probes and only needs a digital camera,fill lights,and pigment.For water colored with diluted pigment,the grayscale index of the water captured by a digital camera depends on the water thickness.This relationship can be utilized to measure the water thickness through digital image processing.In the present study,the relationship between the grayscale index and water thickness was theoretically and experimentally investigated.Both the theoretical derivation and experimental results revealed that for a thin water film,the grayscale index is inversely proportional to the water thickness.
