Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users without expertise in three-dimensional modeling struggle to perform projection mapping due to the need for knowledge of projection target object shapes and coordinate conversions, making it difficult to create effective two-dimensional images for projection.
Innovation Solution
An image editing method and system that uses a camera and processing apparatus to capture and edit images from a position where the camera's and projector's centers overlap, allowing users to easily create projection images without requiring three-dimensional modeling expertise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If three-dimensional modeling and coordinate conversion techniques are used to create projection images, then the accuracy and quality of projection mapping is improved, but the complexity of operation and expertise required increases significantly
Solution Approach 1:
The patent uses a camera to capture an image of the projection target object from the projector's viewpoint, creating a two-dimensional copy that directly represents the three-dimensional object's appearance. This captured image serves as the basis for projection image creation, eliminating the need for manual three-dimensional modeling while preserving accurate visual representation of the target object's shape and features.
Solution Approach 2:
The camera acts as an intermediary device between the projector and the projection target object. By positioning the camera at the projector's location and capturing the target object's image, the system uses the camera as a mediator to obtain accurate two-dimensional projection data without requiring users to perform complex coordinate conversions or three-dimensional modeling operations.
2Manufacturing precision
If three-dimensional modeling knowledge is required for projection mapping, then the precision of projection image creation is improved, but the accessibility and ease of use for general users deteriorates
Solution Approach 1:
The system enables users to create accurate projection images through simple operations: positioning the camera at the projector's location and capturing the target object's image. The camera and processing apparatus automatically perform the complex tasks of coordinate transformation and image generation, allowing users without three-dimensional modeling expertise to achieve professional-quality projection mapping results.
Solution Approach 2:
The patent replaces the manual mechanical process of three-dimensional modeling and coordinate conversion with an automated optical system. The camera captures the target object's image directly from the projector's viewpoint, and the processing apparatus automatically generates the projection image, substituting complex manual operations with automated image capture and processing.
3Manufacturing precision
If complex three-dimensional modeling processes are used, then the quality of projection mapping is improved, but the time required for image creation and processing increases
Solution Approach 1:
The system performs preliminary action by having the user simply capture an image of the projection target object with the camera positioned at the projector's location. This single capture action pre-obtains all necessary visual information about the target object's shape and features, eliminating the need for time-consuming iterative modeling and adjustment processes that would otherwise be required to achieve accurate projection mapping.

AI summary
An information processing apparatus acquires a captured image by causing a camera to image a projection region in a position where a center portion of an imaging range at the time when the projection region including a projection target object in a real space in which a projector and the projection target object are disposed, a first guide image being displayed in the projection region by the projector, and a center portion of the first guide image overlap. The information processing apparatus generates a projection image by causing a user to edit the captured image and transmits projection image data representing the generated projection image to the projector.
