Object Imaging Feedback Control for Missing View Detection

Solution Overview

Problem

Existing image capturing systems may miss data of objects due to obstruction or limited angle of view, making it difficult to identify which parts of the data are missing.

Innovation Solution

A determination device that identifies directions extending from inside to outside of an object in image data, determines if information is missing based on criteria, and controls the imaging device's position to include the missing information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If image capturing is performed with a fixed camera position, then the imaging process is simple and fast, but data of the object may be missing due to obstruction or limited angle of view

Engineering Contradiction:

Improveimaging speedVSAvoidmissing object data

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The system performs preliminary analysis of the captured image to identify directions where object data is missing, then proactively moves the camera to capture additional views before the imaging process is complete, ensuring comprehensive object data collection

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system analyzes captured image data to generate feedback about missing object portions, uses this feedback to determine optimal camera movement directions, and adjusts the camera position accordingly to capture the missing information

Inventive Principle:

Principle #23Feedback

2Loss of information

If the camera moves to expand imaging range, then complete object information can be obtained, but the imaging process becomes more complex and time-consuming

Engineering Contradiction:

Improveobject data completenessVSAvoidimaging process complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The system performs preliminary analysis of the captured image to identify directions where object data is missing, then proactively moves the camera to capture additional views before the imaging process is complete, ensuring comprehensive object data collection

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The camera positioning is dynamically adjusted based on real-time analysis of captured data, allowing the system to adaptively change imaging parameters and positions to optimize data collection efficiency

Inventive Principle:

Principle #15Dynamics

3Loss of information

If the camera moves to capture missing information, then complete object data can be obtained, but imaging time increases

Engineering Contradiction:

Improvemissing data recoveryVSAvoidtotal imaging time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The system performs preliminary analysis of the captured image to identify directions where object data is missing, then proactively moves the camera to capture additional views before the imaging process is complete, ensuring comprehensive object data collection

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system performs partial imaging by focusing only on directions where object data is missing, rather than capturing all directions uniformly, thereby reducing unnecessary imaging time while still recovering complete object information

Inventive Principle:

Principle #16Partial or excessive action

AI summary

The determination device is provided with an identification unit and a determination unit. The identification unit identifies a direction extending from inside to outside of an object in image data or position data. The determination unit then determines whether the identified direction satisfies criteria that indicate that information relating to the object is missing.
