There is deviation between perceived depth andtheoretical depth of virtual object in stereoscopicvirtual environment. This paper analyzes its possiblecauses with optical geometry. In addition, a correctingmethod performed by setting synthetic viewpointdynamically is proposed. Experimental results showthat this method can reduce the depth deviation to lessthan 10 millimeter, meeting the requirements forlocating and direct manipulation in virtualenvironment.
