Abstract :
There is deviation between perceived depth and theoretical depth of virtual object in stereoscopic virtual environment. This paper analyzes its possible causes with optical geometry. In addition, a correcting method performed by setting synthetic viewpoint dynamically is proposed. Experimental results show that this method can reduce the depth deviation to less than 10 millimeter, meeting the requirements for locating and direct manipulation in virtual environment.
