Design and implementation of the maximum dimension algorithm for ice crystal particles recorded by 2D image probe

In order to solve the problem of calculating D
_MAX
with different definitions of particles of arbitrary shapes and calculate the estimation of projection area caused by occlusion of 2D image probe photosensitive areas. This paper proposes a morphological preprocessing of the initial data and combines image spatial information and gray information algorithm to solve the problem of calculating D
_MAX
with different definitions of particles and the problem of estimating the projected area. The experimental result shows that based on this algorithm, D
_MAX
with different definitions of arbitrary shapes can be calculated, the occlusion problem of the photosensitive area can be solved, and the original particle shape is successfully restored, which has important meaning for our study in the fields of cloud physical characteristics analysis, atmospheric mode, and so on.
