Validation of positioning accuracy is very important for assessment of high resolution satellite performance, which can be used as the reference of space optical remote sensor design. For stereo imagery, the general positioning accuracy assessment method can evaluate the positioning accuracy of target point but not the geometric size error of the observed scene. In combination with the circular error probability calculation, the positioning accuracy of a variety of points in the stereo images of WorldView-2 is contrasted and a geometric performance assessment method about geometric size of the observed scene is put forward, which shows that the difference between the two image positioning accuracy is about 47.2764 meters similarly and the geometric size error is only 3.309128 meters. This method is applicable to assessment the performance about geometric size when there is no large scale map or ground control point.
