Solution Overview

Problem

Existing information processing systems struggle to accurately and efficiently identify candidates for assistance, such as wheelchair users, due to the need for complex image processing to determine the presence of wheelchairs.

Innovation Solution

An information processing apparatus that acquires height information from the capturing position of an imaging device and determines whether a user is a candidate for assistance based on this information, without requiring complex image processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If complex image processing is performed to determine wheelchair presence from face area position, then wheelchair detection capability is achieved, but processing efficiency and accuracy are insufficient

Engineering Contradiction:
Improvewheelchair detection accuracyVSAvoidprocessing efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent extracts only the essential feature (face area position in the image) needed for wheelchair detection, rather than performing comprehensive image processing. By focusing solely on detecting the face area and using its position to infer wheelchair presence, the system achieves accurate detection while minimizing processing complexity and time

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The detection process is segmented into distinct steps: first detecting the face area, then determining wheelchair presence based on the face area position. This segmentation allows the system to break down the complex detection task into manageable parts, improving both efficiency and accuracy by handling each aspect separately with appropriate processing methods

Inventive Principle:
Principle #1Segmentation

2Reliability

If comprehensive image processing is performed to identify persons requiring assistance, then detection capability is improved, but processing time and computational load increase

Engineering Contradiction:
Improvecandidate identification accuracyVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary detection of the face area before proceeding to wheelchair presence determination. By first identifying the face area and its position, the system prepares the necessary information in advance, which then enables faster and more accurate determination of whether a wheelchair is present, reducing overall processing time while maintaining high reliability

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent applies partial action by performing only the necessary image processing steps required for detection. Instead of analyzing all image features, it focuses specifically on detecting the face area and using that information to determine wheelchair presence, achieving sufficient detection accuracy with minimal processing time and computational resources

Inventive Principle:
Principle #16Partial or excessive action

AI summary

An information processing apparatus includes: an acquisition unit that acquires height information relating to a height of a capturing position of an imaging device that captured an image in which a face of a user was detected; and a determination unit that determines, based on the height information, whether or not the user is a candidate for person requiring assistance, who may be a person requiring assistance.
