Method and apparatus for plane segmentation of three-dimensional rendering gradient multi-level plane

An apparatus for plane segmentation of a three-dimensional rendering gradient multi-level plane, comprising:

• a memory, memorized with an executable code;
• and
• a processor, coupled with the memory,
• wherein the processor invokes the executable code memorized in the memory to perform a method for plane segmentation of the three-dimensional rendering gradient multi-level plane, and the method comprises:
• performing predetermined first image processing on an acquired target image, so as to obtain a first image processing result corresponding to the target image, the first image processing at least comprising a grayscale conversion;
• performing, in accordance with a predetermined pixel grouping condition, second image processing on the first image processing result, so as to obtain a second image processing result corresponding to the first image processing result, the second image processing comprising three-dimensional projection and pixel grouping, and the second image processing result comprising a plurality of triangular patches;
• performing third image processing on each of the plurality of triangular patches in the second image processing result, so as to obtain a third image processing result corresponding to all of the plurality of triangular patches, the third image processing comprising determination of vertexes for each of the plurality of triangular patches, determination of intersections between a plane where each of the plurality of triangular patches is located and a predetermined section, and connection of the intersections;
• and
• performing, in accordance with the pixel grouping condition, fourth image processing on non-triangular parts in the third image processing result, so as to obtain a fourth image processing result corresponding to the third image processing result, the fourth image processing comprising segmentation processing, classification processing, and gradient color rendering, and the fourth image processing result comprising a target rendered image corresponding to the target image.

A non-transitory computer memory medium, wherein, the non-transitory computer memory medium memorizes computer instructions, and the computer instructions, when invoked, are configured to cause a method for plane segmentation of a three-dimensional rendering gradient multi-level plane to be performed, and the method comprises:
