Solution Overview

Problem

Existing visual positioning systems (VPS) do not effectively integrate and present evaluation observation results in an easy-to-understand manner, making it difficult for evaluators to determine the accuracy of 3D map creation, and there is a lack of methods to provide imaging position and direction information in cases of successful and unsuccessful estimation.

Innovation Solution

An information processing device and method that acquires evaluation images and imaging information, estimates the imaging position and direction, creates an evaluation map with success-or-failure related information, and updates this information based on estimation outcomes, allowing for clear presentation of successful and failed estimations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If evaluation results of VPS are integrated and presented, then evaluator can determine accuracy of 3D map creation, but system complexity increases

Engineering Contradiction:
Improveevaluation accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The evaluation map divides the evaluation results into distinct segments: successful estimations are marked with one visual indicator (e.g., checkmarks or green indicators) while unsuccessful estimations are marked with different visual indicators (e.g., crosses or red indicators). This segmentation allows evaluators to clearly distinguish between successful and unsuccessful estimations at different imaging positions and directions, improving evaluation accuracy without overwhelming system complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The evaluation map serves as an intermediary visual interface between the complex VPS estimation processes and the evaluator. It consolidates multiple estimation results into a single comprehensive visual representation, allowing evaluators to assess 3D map accuracy without directly analyzing complex raw data from multiple estimation operations

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If both successful and unsuccessful estimation information is provided, then evaluator can comprehensively assess VPS performance, but information processing complexity increases

Engineering Contradiction:
Improveinformation completenessVSAvoidinformation processing complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The evaluation map merges multiple pieces of information into a single integrated visual display. It combines successful estimation results, unsuccessful estimation results, imaging positions, and imaging directions into one comprehensive map. This merging approach ensures complete information is provided to evaluators while simplifying the presentation compared to providing separate detailed reports for each estimation result

Inventive Principle:
Principle #5Merging (Combining)

3Measurement precision

If evaluation map is updated with latest estimation results, then evaluation accuracy is maintained, but processing time increases

Engineering Contradiction:
Improveevaluation accuracyVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The evaluation map is prepared in advance with the necessary structure and framework for receiving estimation results. The map includes pre-defined visual indicators and spatial organization for displaying successful and unsuccessful estimations. This preliminary preparation allows estimation results to be quickly integrated and displayed without requiring complex real-time processing or restructuring, thus maintaining evaluation accuracy while minimizing processing time

Inventive Principle:
Principle #10Preliminary action

AI summary

There is provided an information processing device, an information processing method, and a program capable of providing an imaging position and an imaging direction in both a case where estimation is successful and a case where estimation fails, in a case where the imaging position and the imaging direction are estimated. A reception unit acquires an evaluation image and imaging information for evaluation. An estimation unit estimates the imaging position and the imaging direction of the evaluation image by performing matching between the feature point of a 3D map and the feature point of the evaluation image. An evaluation map creation unit creates an evaluation map in which success-or-failure related information regarding whether or not estimation has been successful is registered in association with the imaging position and the imaging direction of the evaluation image. An evaluation map update unit updates the success-or-failure related information corresponding to the estimated imaging position and imaging direction in a case where the estimation is successful, and updates the success-or-failure related information corresponding to the imaging position and imaging direction indicated by the imaging information for evaluation in a case where the estimation fails. The present technology can be applied to, for example, a server or the like.
