Abstract
A method of improving an occluded edge quality in an augmented reality system comprises: a data input step of using a camera set to capture a scene and an object set in the scene to obtain an original image; an occluded region extracting step of obtaining an extracted image by performing a difference operation according to first and second image, which are obtained according to depth buffer calculations performed on the original image and first and second virtual planes set in the scene; and an occluded image generating step of inserting an virtual object into the original image according to the extract image, the original image and a third virtual plane set between the first and second virtual planes to obtain an occluded image with a smooth occluded edge.
