研究目的
To extend the color gamut controllable by projection mapping systems by leveraging human perception and visual illusions, specifically color constancy, to make objects appear as colors outside the system's inherent limitations.
研究成果
The research demonstrates that color constancy can be induced to expand the color gamut of projection mapping systems, allowing objects to appear as colors outside the system's physical limitations. Future work should address non-linear perceptual aspects and conduct user studies for validation, with potential applications in assisting color-vision deficient individuals.
研究不足
The model assumes linear color modifications in RGB space, which may not accurately represent human perceptual linearity. The method is constrained to lambertian surfaces and uniform white environmental light, and has not been validated through user studies.
1：Experimental Design and Method Selection:
The study employs a projector-camera system to project light onto objects, utilizing color constancy illusions to manipulate perceived colors. Theoretical models involve linear transformations in RGB space to account for color mixing and human perception.
2：Sample Selection and Data Sources:
A ColorChecker target with specific colors (rose and pink) is used as the object for appearance modification. Data is derived from the object's reflectance and environmental light conditions.
3：List of Experimental Equipment and Materials:
A projector (unspecified model and brand) and a camera (unspecified) are used for projection and capture. The ColorChecker target serves as the sample surface.
4：Experimental Procedures and Operational Workflow:
Project colored light onto the object and surrounding areas to induce color constancy. Adjust projection colors based on calculations to achieve target perceived colors (e.g., changing rose to blue and pink to gray).
5：Data Analysis Methods:
Analysis involves comparing the actual reflected light with the perceived color using linear models in RGB space, with plans to extend to perceptually linear spaces like Lab in future work.
