SNOWFALL DEPTH AUTOMATIC MEASUREMENT METHOD AND DEVICE THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a snowfall depth automatic measurement device capable of preventing a measurement error of snowfall depth even if a scanning angle of distance measurement light is varied due to bending of a brace on which a measurement housing is disposed.SOLUTION: The measurement housing comprising light feeding means 1, light receiving means 4, and light scanning means 2 is disposed on the brace standing on a ground surface. Inclination angle information Aof the brace is detected by inclination angle detection means 11, and inclination correction means 12 corrects scanning angle information Kon plural measurement points based on the inclination angle information outputted from the inclination angle detection means, thereby measurement accuracy of snowfall depth is improved.
