Abstract

The present invention proposes a particle analysis method based on three-dimensional morphology, which includes the following steps: scanning the particles with multiple viewing angles to obtain point cloud data of the particles under multiple viewing angles; splicing the point cloud data under multiple viewing angles; Denoise the spliced ​​point cloud data to obtain the final point cloud data; construct the mesh model of the three-dimensional surface morphology of the particles according to the final point cloud data; render and display the mesh model of the three-dimensional surface morphology to obtain the final point cloud data according to the display results Analyze and count the geometric and morphological properties of particles. The method according to the embodiment of the present invention can conveniently realize three-dimensional fine measurement, reconstruction, three-dimensional visualization and quantitative analysis of particle morphology. The invention also provides a particle placing bracket.

Description

technical field

[0001] The invention relates to the technical field of particle analysis, in particular to a three-dimensional shape-based particle analysis method and a particle placement bracket. Background technique

[0002] Particles are ubiquitous in nature and form the basis of most matter. In agricultural engineering, the morphological characteristics of seeds are an important indicator for evaluating seed quality; in geotechnical engineering, block stone particles are an important part of complex rock-soil media such as concrete, rockfill materials, and soil-rock mixtures. It will directly affect the physical and mechanical properties of the material and the mechanism of deformation and fracture.

[0003] Traditional particle analysis usually uses the sieving method to obtain the particle size composition of particles, or obtains its two-dimensional shape information through two-dimensional digital image processing. However, these methods can only achieve rough ana...
