Spatial information recovering from 2D images is one of key element of imagine processing technique. This study develops a method based on the parity of two images to recover the 3D information of an object from 2D images. First, the 2D information of the characteristic points of left and right images is extracted from, then the 3D information of these characteristic points is recovered using the method developed in this study and the parameters of the CCD system. These points’ 3D information is then used to construct a reference plane by using the least square method and Newton’s method. Three examples are given to demonstrate the feasibility of the proposed method. The real positions of the object are known. The comparison results show that the proposed method can recover the object’s 3D information. The error of normal vector and the mid-point coordination of the reference plane calculated from the recovered 3D information are within the acceptable range.
