AI Technical Summary

Technical Problem

Existing methods for generating parallel cross-sectional images of a three-dimensional shape model generate multiple similar images where the cross-sectional shape change is small, leading to inefficiencies in calculation speed and memory usage.

Method used

An image processing method that acquires distance values from a predetermined plane to each part of the three-dimensional shape model, determines distances based on these values, and generates cross-sectional images only at positions where the minimum value changes to a threshold or greater, optimizing the generation process.

Benefits of technology

This method enables more efficient generation of multiple parallel cross-sectional images by minimizing the number of images required, thus improving calculation speed and memory efficiency.
