Embodiment Construction

[0041] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. It should be noted that relative terms such as "first", "second" and so on may be used to describe various components, but these terms do not limit the components. These terms are only used to distinguish one component from another. For example, without departing from the scope of the present invention, a first component may be called a second component, and a second component may similarly be called a first component. The term "and / or" refers to any one or more combination of related items and described items.

Abstract

The invention discloses a method for generating two-dimensional irregular virtual particles, which comprises the following steps of: S10, carrying out first processing on the particles to obtain a first plane projection image corresponding to the particles; S20, determining a quality center of the first plane projection image, and establishing a rectangular coordinate system by taking the qualitycenter as an original point; S30, constructing a first equivalent ellipse according to the coordinate values corresponding to the pixel points in the first plane projection image in the rectangular coordinate system; S80, calculating a second residual radius; S90, calculating a polar radius corresponding to the central angle; and S100, calculating a radius r and a radius corresponding to the central angle according to the polar radius and the second residual radius, and generating virtual particles according to the central angle and the radius. The method can be suitable for more particles, and the generated virtual particles are slightly different from real particles.
