Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The accuracy of three-dimensional data generated by multiple cameras is often insufficient due to suboptimal camera arrangements, requiring repeated rearrangement, calibration, and verification, which is labor-intensive and time-consuming.
Innovation Solution
An information processing apparatus and method that calculates an evaluation value for camera arrangements to determine the optimal setup for generating three-dimensional data, using an evaluation section to assess the arrangement based on internal parameters, viewing area, and installation area information, and displaying this information to facilitate easier setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If camera arrangements are determined based on photographer experience, then the arrangement process is simple, but the accuracy of generated three-dimensional data is insufficient
Solution Approach 1:
The patent pre-calculates and stores optimal camera arrangements in a database before actual photographing. The arrangement determination section queries this pre-prepared database to select appropriate arrangements, eliminating the need for complex real-time calculations during photographing while ensuring high accuracy three-dimensional data generation.
Solution Approach 2:
The patent creates a virtual model of the photographing environment including camera positions, viewing areas, and installation areas. This virtual model is used to simulate and evaluate different camera arrangements, allowing selection of optimal configurations without physical trial-and-error, thus improving accuracy while maintaining simplicity.
2Measurement precision
If repeated rearrangement and calibration are performed to achieve sufficient accuracy, then the accuracy of three-dimensional data improves, but labor and time consumption increase
Solution Approach 1:
The patent pre-calculates optimal camera arrangements and stores them in a database before actual photographing operations. When photographing is needed, the arrangement determination section simply queries this pre-prepared database to select the appropriate arrangement, eliminating the need for repeated trial-and-error adjustments and calibration during the actual work process.
Solution Approach 2:
The patent incorporates an evaluation mechanism that assesses camera arrangements based on viewing areas, installation areas, and photographing requirements. This feedback system guides the selection of optimal arrangements from the database, ensuring high accuracy while minimizing the number of adjustments needed.
3Measurement precision
If multiple camera arrangements are evaluated manually, then the optimum arrangement can be found, but the process becomes labor-intensive
Solution Approach 1:
The patent implements an automated arrangement determination system that autonomously queries the database, evaluates photographing requirements, and selects optimal camera arrangements without manual intervention. The system automatically determines the best configuration based on stored pre-calculated arrangements and current photographing conditions, significantly reducing labor while maintaining high accuracy.
Solution Approach 2:
The patent replaces manual evaluation and selection of camera arrangements with an automated information processing system. The arrangement determination section uses computer-based querying and evaluation algorithms to automatically select optimal arrangements from the database, substituting manual mechanical processes with automated computational processes.
