Abstract
In a method for displaying a virtual object (), a scene () is imaged. The scene comprises a target apparatus (). The target apparatus comprises a set of color target elements () having known reflectance properties and at least one illumination target element () having a plurality of known surface normals. At least one image of the scene is processed to determine measured colors for the color target elements and illumination and viewing conditions for the scene. Color transformation parameters are calculated by comparing the measured colors and the known reflectance properties of the color target elements. The virtual object is rendered for the determined illumination and viewing conditions. The rendered virtual object is aligned with the scene. A color transformation is applied to the imaged scene and/or to the virtual object, and an overlay of the rendered virtual object with the imaged scene is displayed on a display device () in real time while the illumination and/or viewing conditions are changed.
