Abstract
A method of detecting a protrusion in an intestinal tract in a computer according to an embodiment of the present disclosure includes acquiring a three-dimensional model of the intestinal tract scanned by a scanning device, the three-dimensional model comprising three-dimensional data of the intestinal tract; mapping, in the computer, the three-dimensional model to a two-dimensional plane in an area-preserving manner; and detecting an area of the protrusion in the two-dimensional plane. The method can replace traditional modes such as enteroscopy, and the protrusion in the intestinal tract is detected in a painless and low-cost mode.

A method of detecting a protrusion in an intestinal tract in a computer, comprising:
- acquiring a three-dimensional model of the intestinal tract scanned by a scanning device, the three-dimensional model comprising three-dimensional data of the intestinal tract;
- mapping, in the computer, the three-dimensional model to a two-dimensional plane in an area-preserving manner;
- and
- detecting an area of the protrusion in the two-dimensional plane;
- wherein the mapping the three-dimensional model to a two-dimensional plane in an area-preserving manner comprises:
- determining a boundary of the two-dimensional plane;
- harmonically mapping the three-dimensional data to an interior of the boundary to form harmonic mapping points;
- calculating second weights of the harmonic mapping points, and further calculating a weighted Voronoi diagram of the harmonic mapping points;
- and
- mapping the three-dimensional model to the two-dimensional plane in the area-preserving manner according to the weighted Voronoi diagram.
