Image Processing Stabilization for Projection Surface Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for deforming a projection surface based on the distance between a moving object and an obstacle can result in unnatural displayed images due to fluctuations in measurement distances, leading to unstable projection images.
Innovation Solution
The image processing apparatus employs distance stabilization processing to convert measurement distances into stabilization distances, which are used to deform the projection surface, thereby stabilizing the image and preventing unnatural fluctuations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the projection surface is deformed based on the measurement distance between the moving object and the obstacle, then the projection image can adapt to distance changes, but the displayed image becomes unnatural due to temporal fluctuations in measurement distance
Solution Approach 1:
The patent applies preliminary action by performing distance stabilization processing before deforming the projection surface. The measurement distance is converted into a stabilized distance that filters out temporal fluctuations, ensuring that the projection surface deformation is based on reliable distance information rather than noisy instantaneous measurements.
Solution Approach 2:
The patent introduces an intermediary element - the distance stabilization processing unit - that acts as a mediator between the raw measurement distance and the projection surface deformation. This intermediary converts the fluctuating measurement distance into a stabilized distance through processing, preventing direct transmission of fluctuations to the projection image.
2Ease of operation
If the projection surface is deformed in real-time according to distance changes, then the image can reflect current spatial relationships, but the image becomes unstable and unnatural due to measurement fluctuations
Solution Approach 1:
The system performs distance stabilization processing in advance before using the distance information for projection surface deformation. This preliminary processing ensures that only stable, representative distance values are used, preventing real-time fluctuations from affecting the projection image while maintaining accurate spatial relationships.
Solution Approach 2:
The patent implements a feedback mechanism where the stabilized distance information is continuously updated and used to adjust the projection surface. The feedback loop ensures that the projection image reflects spatial relationships accurately while filtering out transient fluctuations through the stabilization processing.

AI summary
In one aspect, an image processing apparatus includes a determination unit and a deformation unit. The determination unit executes first distance stabilization processing of converting a measurement distance between a three-dimensional object around a moving object and the moving object into a first distance or a second distance smaller than the first distance as a stabilization distance based on the magnitude relation between the measurement distance and the first threshold. The deformation unit deforms a projection surface of a peripheral image of the moving object based on the stabilization distance.
