Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional methods are used to enhance resolution of three-dimensional point clouds, then resolution enhancement is attempted, but the quality degrades when associated points cannot be specified

Engineering Contradiction:

Improveresolution enhancement qualityVSAvoidspecifiability of associated points

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The patent applies inversion by rotating the coordinate system or the point cloud data by 180 degrees to generate converted points. This allows the system to specify associated points for symmetrical objects by utilizing their inverted counterparts, thereby resolving the issue where associated points cannot be specified in conventional methods. The inversion principle enables reliable point specification even when direct associated points are unavailable.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent creates converted points by copying and transforming existing points through rotation or inversion operations. These converted points serve as substitutes for unavailable associated points, maintaining resolution enhancement quality. The copying mechanism ensures that sufficient points are available for specification without requiring additional physical points to exist in the original data.

Inventive Principle:

Principle #26Copying

2Reliability

If rotation or inversion operations are performed on second three-dimensional points, then the number of specifiable points increases, but the processing complexity increases

Engineering Contradiction:

Improvespecifiability of associated pointsVSAvoidprocessing complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent changes the parameter of point transformation by applying rotation or inversion operations to generate converted points. This parameter change enables the system to specify associated points that would otherwise be unavailable, improving reliability without requiring complex additional hardware or systems.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent performs rotation or inversion operations in advance to generate converted points before the actual resolution enhancement process. This preliminary action ensures that converted points are ready for specification, reducing processing complexity during the main enhancement operation by pre-computing the transformed points.

Inventive Principle:

Principle #10Preliminary action

3Measurement precision

If converted second three-dimensional points are generated through rotation or inversion, then resolution enhancement quality improves, but the data processing time increases

Engineering Contradiction:

Improveresolution enhancement qualityVSAvoiddata processing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies rotation or inversion operations selectively to second three-dimensional points based on their spatial relationship to the first point. This local application of transformation ensures that only necessary points are converted, improving resolution enhancement quality while minimizing unnecessary processing time for points that do not require conversion.

Inventive Principle:

Principle #3Local quality

AI summary

A three-dimensional point generation method for generating one or more three-dimensional points in a three-dimensional coordinate system includes: performing at least one of rotation or inversion on one or more second three-dimensional points located in a vicinity of a first three-dimensional point to generate one or more converted second three-dimensional points; and specifying one or more third three-dimensional points associated with the one or more converted second three-dimensional points.
