Abstract
A device for measuring a reflectivity of an object at the seabottom, includes a spectral probe, a first white board, a second white board, a distance meter, and a shaft; the first white board and the second white board respectively have a known reflectivity; the first white board and the second white board are connected to the shaft, wherein the first white board and the second white board are spaced along an axial direction of the shaft and staggered from each other along a radial direction of the shaft; the spectral probe is configured to collect spectral data of the first white board, the second white board and the object at the seabottom; the distance meter is configured to collect distance data between the spectral probe and the object at the seabottom.
