Abstract
This invention discloses a method for measurement and 3D reconstruction of precipitation particles based on orthogonal dual-view imaging. An orthogonal 3D sampling space are formed by a pair of line camera and continuum light source, two pairs of planar cameras and pulse light sources placed orthogonally. The line camera scans with a speed no less than 20,000 lines per second, two cameras and pulse light sources are triggered when the line camera detects the particles in sampling area, two orthogonal images are recorded by two planar cameras using the double-exposure or multiple-exposure in one frame. The 3D images of particles are obtained by pixel matching and grid reconstruction method, based on which the 3D sizes, axis ratio, orientation, fall velocity, and other characteristics of particles are calculated. This method can measure the 3D micro-physical characteristics of precipitation particles automatically and precisely.
