1Measurement precision
If laser beam reflection method is used to measure snow thickness, then measurement capability is provided, but measurement precision is insufficient to accurately determine deposited material states
Solution Approach 1:
The patent transitions from one-dimensional thickness measurement to two-dimensional state characterization by capturing both optical scattering properties and spatial distribution information. The image processing system analyzes multiple dimensions of light interaction data to simultaneously determine thickness, quality, and density, resolving the information loss problem of conventional single-parameter measurement methods
Solution Approach 2:
The patent introduces an intermediary image processing system that mediates between the raw optical detection data and the final material state determination. This intermediary layer processes scattering patterns and spatial information through image algorithms to extract comprehensive material characteristics, enabling accurate determination of multiple parameters simultaneously
