Dynamic Luminance Correction with a Projector-Camera System
Details
Recently, the application fields of image projection are diversified with the appearance of portable projectors. In such case, image deterioration with projection onto arbitrary surfaces, not decided screen material, is caused with the difference of color and reflectance properties of the surfaces. Therefore, we propose a dynamic luminance correction method with a projector-camera system. This method requires no prior and complex measurements of target's color and reflectance properties, used in previous approaches. By using the projector-camera system, in our approach, projected luminance is immediately captured, and based on that, corrected pixel value for each pixel is calculated with some iterative estimation processes. This technique makes it possible to project images onto the surface which is suddenly moved or shaded with other objects having different reflectance property.
