Projection Device Multi-Device Image Overlap Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection devices struggle to prevent image overlap when multiple devices are tracking a moving object, leading to unclear information transmission due to overlapping projected images.
Innovation Solution
A projection device with a detection unit, projection unit, drive unit, and controller that adjusts the projection image's position and method to avoid overlap by receiving information from other devices, using techniques such as detouring, repulsive forces, erasing overlapping parts, or changing image size to ensure non-overlapping projections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple projection devices track and project images following the same moving object, then information can be presented to multiple viewers or perspectives, but the projected images will overlap making information unclear
Solution Approach 1:
Each projection device projects its image with locally optimized quality by adjusting projection position, size, and orientation based on its specific viewing angle and distance from the moving object, ensuring clear information presentation for its target audience without interfering with other devices
Solution Approach 2:
The system resolves image overlap by utilizing additional spatial dimensions - adjusting projection positions in horizontal, vertical, and depth directions, as well as varying projection sizes and orientations, to distribute multiple images across the available space without overlap
2Ease of operation
If a single projection device follows a moving object, then information can be dynamically presented to the object's location, but multiple devices cannot independently track without causing image overlap
Solution Approach 1:
The system implements feedback mechanisms where each projection device receives information about the positions and projection parameters of other devices, and continuously adjusts its own projection characteristics based on this feedback to maintain optimal separation and avoid overlap while preserving dynamic tracking functionality
Solution Approach 2:
The system dynamically adjusts projection parameters (position, size, orientation) in real-time based on the relative positions of multiple devices and the moving object, allowing each device to maintain easy operation for dynamic presentation while the collective system manages complexity through coordinated adaptation

AI summary
A projection device includes: a detection unit configured to detect a specific object; a projection unit configured to project a first projection image; a drive unit configured to change a direction of the projection unit so as to change the projection position of the first projection image; a controller configured to control the drive unit such that the first projection image is projected while following the motion of the detected specific object; and a communication unit configured to receive information of a second projection image projected by another projection device. The controller acquires information relating to a position of the second projection image through the communication unit, and controls a projection method of the first projection image based on the positions of the first projection image and the second projection image such that the first projection image and the second projection image are not overlapped with each other when they are projected.
