| titleOfInvention | Method for estimating soil-derived suspension concentration in inland water |
| abstract | The present invention provides a non-contact estimation method for the concentration of suspended matter derived from soil in land water that is not easily affected by differences in observation direction and bottom color. SOLUTION: From the reflected light of sunlight on the surface of land water, one wavelength band included in the short wavelength infrared region, one wavelength included in the near infrared region, and one wavelength band included in the band visible region. It is a method for estimating the concentration of suspended solids derived from soil in land water by measuring non-polarized reflectance and performing processing, wherein the short-wavelength infrared region is a wavelength range of 1500 to 2300 nm, and the near-infrared band is a wavelength of 750 In the range of ˜1300 nm, the visible range is preferably in the range of wavelength 450 to 700 nm, and the present invention is further characterized in that the measurement of the non-polarized reflectance is such that the reflected light for each wavelength band rotates around the optical axis. It is preferable to calculate from the ratio of the polarization reflection intensity in the wavelength band reflected light detected by passing through the polarizing filter. [Selection figure] None. |
