1. A method for detecting 3D pseudoscopic images, comprising: extracting corresponding feature points in a first view and corresponding feature points in a second view, wherein the first view and the second view form a current 3D image; calculating an average coordinate value of the feature points in the first view and an average coordinate value of the feature points in the second view; based on the average coordinate value of the feature points in the first view and the average coordinate value of the feature points in the second view, determining whether the current 3D image is pseudoscopic or not; and processing the current 3D image when it is determined that the current 3D image is pseudoscopic.
