Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for digital operations on three-dimensional objects require a large number of viewpoints, leading to increased computation complexity, storage resources, and power consumption, especially when dealing with complex geometries.
Innovation Solution
The technique involves determining a subset of activated viewpoints from a set of candidate viewpoints, reducing overlap and maintaining sufficient surface data coverage for digital operations, thereby optimizing the number of viewpoints used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a large number of viewpoints are used to view outer surfaces of three-dimensional objects, then surface data coverage is improved, but computation complexity increases
Solution Approach 1:
The patent extracts and removes redundant viewpoints from the set of candidate viewpoints. By analyzing overlap between viewpoints and identifying which viewpoints provide duplicate surface data, the system selectively removes unnecessary viewpoints while retaining those that contribute unique surface information, thereby reducing computation complexity while maintaining adequate surface coverage
Solution Approach 2:
The patent applies partial action by determining a subset of activated viewpoints rather than using all candidate viewpoints. The system activates only the necessary portion of viewpoints required to achieve sufficient surface data coverage, avoiding the excessive use of all available viewpoints and thereby reducing computational overhead
2Measurement precision
If a large number of viewpoints are used to view outer surfaces of three-dimensional objects, then surface data coverage is improved, but storage resources increase
Solution Approach 1:
The patent extracts and eliminates redundant viewpoint data from storage requirements. By identifying viewpoints that provide overlapping surface data, the system removes the need to store duplicate viewpoint information, thereby reducing storage resources while maintaining complete surface coverage through the remaining activated viewpoints
Solution Approach 2:
The patent applies partial action by storing only the necessary subset of activated viewpoints rather than all candidate viewpoints. The system determines which viewpoints are needed for adequate surface coverage and stores only those, avoiding the excessive storage of redundant viewpoint data
3Measurement precision
If a large number of viewpoints are used to view outer surfaces of three-dimensional objects, then surface data coverage is improved, but power consumption increases
Solution Approach 1:
The patent extracts and removes unnecessary viewpoints from the active set. By identifying and eliminating viewpoints that provide redundant surface data, the system reduces the number of viewpoint operations that require computational power, thereby reducing power consumption while maintaining adequate surface coverage
Solution Approach 2:
The patent applies partial action by activating only the necessary portion of viewpoints required for sufficient surface data coverage. The system determines which viewpoints are needed and activates only those, avoiding the excessive activation and processing of all candidate viewpoints, thereby reducing power consumption
4Device complexity
If a subset of activated viewpoints is determined to reduce the number of viewpoints, then computation complexity is reduced, but surface data coverage may be insufficient
Solution Approach 1:
The patent applies feedback by iteratively evaluating the surface data coverage provided by the subset of activated viewpoints. The system determines an initial subset of activated viewpoints, evaluates whether sufficient surface coverage is achieved, and if not, adds additional viewpoints to the activated subset until adequate coverage is obtained, thereby ensuring both reduced computation complexity and sufficient surface data coverage
Solution Approach 2:
The patent applies preliminary action by pre-analyzing the overlap between candidate viewpoints before finalizing the activated subset. The system evaluates surface data overlap in advance and strategically selects which viewpoints to activate to ensure comprehensive coverage, avoiding the need for excessive viewpoints while maintaining adequate surface data coverage

AI summary
Implementations of systems and methods for determining viewpoints suitable for performing one or more digital operations on a three-dimensional object are disclosed. Accordingly, a set of candidate viewpoints is established. The subset of candidate viewpoints provides views of an outer surface of a three-dimensional object and those views provide overlapping surface data. A subset of activated viewpoints is determined from the set of candidate viewpoints, the subset of activated viewpoints providing less of the overlapping surface data. The subset of activated viewpoints is used to perform one or more digital operation on the three-dimensional object.
