Engineering Contradiction Analysis
1Reliability
If traditional interpolation methods (e.g., trilinear interpolation) are used, then reliability of interpolated values is improved, but interpolation speed deteriorates
Solution Approach 1:
The patent segments the three-dimensional space into multiple planes and performs interpolation plane by plane. Instead of treating the entire 3D space as one complex interpolation problem, the method divides it into manageable two-dimensional planes, reducing computational complexity while maintaining accuracy. This segmentation allows for faster processing by breaking down the interpolation task into smaller, more efficient sub-tasks.
Solution Approach 2:
The patent transforms the three-dimensional interpolation problem into a series of two-dimensional plane interpolation problems. By projecting the 3D point onto 2D planes and performing interpolation in this reduced dimensionality, the computational burden is significantly reduced while still capturing the essential spatial relationships. This dimensional reduction is a key strategy for improving interpolation speed without sacrificing reliability.
2Measurement precision
If extensive computation and communication are performed to improve interpolation accuracy, then reliability is improved, but processing time increases
Solution Approach 1:
The patent performs preliminary actions by pre-organizing the three-dimensional space into structured planes and pre-identifying the relevant vertices for each plane. This preliminary structuring allows the interpolation process to directly access the necessary data without extensive searching or computation during the actual interpolation operation, thereby reducing processing time while maintaining accuracy.
Solution Approach 2:
The patent applies local quality by focusing computational resources on the specific plane and vertices most relevant to the interpolation point, rather than processing the entire three-dimensional space uniformly. By identifying and working only with the nearest plane and its vertices, the method achieves high accuracy with minimal computation, avoiding unnecessary processing time.

AI summary
An image interpolation method interpolating image information of a point in a space constructed by a plurality of planes. According to the method, a reliable interpolated value can be rapidly obtained by searching for the nearest plane to the point, obtaining information about a plane facing the nearest plane using image information of one or more vertices of the plane facing the nearest plane, and interpolating the image information of the point using the image information of the one or more vertices of the nearest plane and the obtained information about the plane facing the nearest plane.
