A new servo control methods for O-E theodolite is presented in this paper. The methods integrates optimally feed forward and feedback control
and adopts acceleration delay compensation based on velocity delay compensation
then achieves servo control of O-E theodolite effectively. Furthermore
Angular acceleration sensor is applied as information resources
and adaptive filter is formed to provide with feed forward control signal in the methods. For double closed loop servo control system of O-E theodolite
the location correction loop and velocity correction loop are analyzed and designed. Simulation and experimental results show that comparing with traditional methods
this servo control methods can improve significantly tracking precision and stability of O-E theodolite. 2010 IEEE.

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.
