In this paper  a method of measuring the 3-D pose of the remote revolving target such as rocket or missile by using the intersected measuring system with a proper algorithm is described. This passage creates a math model of intersected measuring system with dual - photoelectric theodolite and the formula to calculate the target attitude angles are presented.The measuring precision of this method is analyzed in detail by using the relative error theory  and then it makes optimization design for structure parameters of intersected measuring system with dual - photoelectric theodolite by computer simulation  so different optimization results according to different location of target are obtained  and the system lay-out  measuring principles are also presented. By using this method we may acquire the measuring precision higher than 0.5 if the measuring stations are arranged correctly.

The geometric distortion of infrared image  which was created by the large-sized relative aperture optical system. It could be corrected by the digital image processing technology. The magnitude of distortion would be enlarged quickly with the enlargement of relative aperture. Though the distortion could not impact on the articulation of the image  it would affect geometric location precision of the image directly. In this paper  the distortion correction of uncooled large-sized relative aperture infrared imaging system was discussed and the mathematical model of distortion correction was established. A algorithm of digital image processing was presented and applied based on control points by combining polynomial warping and space variant linear image interpolation. The method of polynomial warping was used to establish the locality relationship between the original image and the distortion ones. The space-variant linear image interpolation provided an efficient way to rebuild the frame of images. The computational costs of the proposed approach are very little and the precision is almost as high as the method of bicubic interpolation when compared to those of state-of-the-art nonlinear interpolation operators.
