| Research Abstract |
It was a fact among the tunnel engineers from the era of analog cameras that the white marks appear in the flashed photograph during the tunnel construction. This reason is that suspended dusts reflect like a snow by Mie scattering of flash light. By using this phenomenon, the simple dust concentration measurement by using digital camera was developed. This measurement system was based on the neural network system. This neural network system studies the relationship the value of the digital dust indicator and the whiteness of the flashed digital camera. As a result, it found that simple dust concentration measurement from the digital camera flash image has a good relationship the value of digital dust indicator.
