A present invention provides a method for constructing a highly accurate visual hull from multi view point images without highly accurate silhouettes. A method of the present invention comprises calculating continuous values to represent background likelihood of each pixel for every object image based on pixel values of said object images and those of said background images, calculating the projection pixels for each voxel at every captured view point by projecting each voxel in voxel space on each captured view point of said object images, and determining an object domain with judging whether said voxel belongs to the object domain or not based on the continuous value of said pixel at every captured view point.
