Solution Overview

Problem

Existing projection technologies, such as those described in JP2016-208255A and JP2017-076084A, face challenges in dynamically adjusting projection target positions and moving object positions to optimize image projection quality and efficiency, particularly in dynamic environments with changing target conditions.

Innovation Solution

A control device and method that acquires target information to determine and update projection target positions and moving object positions in real-time, using a processor to control a moving object with a projection apparatus, allowing for flexible adjustment during movement to ensure optimal projection quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the moving object moves to the determined target moving object position, then the projection can be performed at the determined projection target position, but the target position may change during movement resulting in suboptimal projection quality

Engineering Contradiction:

Improveprojection qualityVSAvoidtime to initiate projection

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent implements dynamic updating of the projection target position and target moving object position during the movement process. The control device continuously acquires updated target information and recalculates optimal positions, allowing the system to adapt to changing conditions rather than relying on static pre-determined positions. This dynamic approach ensures projection quality is maintained even as environmental conditions change during movement.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system employs feedback mechanisms by continuously acquiring target information (such as target position, orientation, and environmental conditions) during movement and using this information to update the projection parameters. This closed-loop control allows the system to respond to real-time changes and maintain optimal projection quality throughout the movement process.

Inventive Principle:

Principle #23Feedback

2Ease of operation

If the system determines projection target position and target moving object position based on initial target information, then the projection setup is straightforward, but changing target conditions during movement result in inaccurate projection positioning

Engineering Contradiction:

Improveprojection setup simplicityVSAvoidprojection target positioning accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The system transitions from static position determination to dynamic position updating. While the initial setup remains simple based on initial target information, the system continuously updates positions during movement by acquiring new target information and recalculating optimal positions, thereby maintaining both operational simplicity and positioning accuracy throughout the process.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system performs preliminary determination of projection target position and target moving object position based on initial target information to enable quick setup. This preliminary action provides a starting point that is then refined through continuous updates during movement, combining the benefits of rapid initialization with ongoing precision optimization.

Inventive Principle:

Principle #10Preliminary action

3Stability of the object's composition

If the projection apparatus projects to a fixed target position, then the projection system is stable, but it cannot adapt to changing target conditions during movement

Engineering Contradiction:

Improveprojection system stabilityVSAvoidadaptation to changing target conditions

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent implements a dynamic projection system that continuously updates the projection target position based on current target information acquired during movement. This allows the system to maintain stability through controlled, incremental adjustments rather than abrupt changes, adapting to evolving conditions while preserving overall system stability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system uses feedback from continuously acquired target information to adjust projection parameters in real-time. This feedback mechanism enables the system to adapt to changing target conditions while maintaining stability through smooth, controlled adjustments based on measured deviations from optimal positions.

Inventive Principle:

Principle #23Feedback

AI summary

A control device, that controls a moving object on which a projection apparatus is mounted, includes a processor, and the processor is configured to: acquire first target information related to a state of a first target; determine a projection target position and a target moving object position based on the first target information; move the moving object to the target moving object position; perform projection to the projection target position from the projection apparatus; and during moving of the moving object to the target moving object position, acquire second target information related to a state of the first target and update at least one of the projection target position or the target moving object position based on the second target information.
