Three-dimensional snow mass flux measurement method and device and computer equipment

Abstract

This invention provides a method, apparatus, and computer device for measuring three-dimensional snow mass flux. The method includes: performing three-dimensional dynamic imaging of snow particles passing through the orthogonal dual-field-of-view measurement area using an orthogonal dual-field-of-view telecentric optical imaging module, and acquiring the morphological parameters, spatial position, and three-dimensional velocity vector of individual snow particles; measuring the mass of snow particles falling into the snow particle mass measurement area using a visible light thermal infrared multi-angle imaging module, and retrieving the mass and density of individual snow particles; performing spatiotemporal alignment and fusion processing on the data acquired by the orthogonal dual-field-of-view telecentric optical imaging module and the visible light thermal infrared multi-angle imaging module using a synchronous control and data fusion processing module to obtain comprehensive parameters of the snow particles; and calculating the three-dimensional snow mass flux of the corresponding area based on the comprehensive parameters. This method can directly and accurately acquire the mass and density of individual snow particles and significantly improve the accuracy of microphysical parameter measurement.
