This paper proposed a sub-pixel image correlation algorithm that can get more Precise result
its principle is apply the distribute of relativity peak to get weighted multi-pixel comprehensive of location. Image correlation be as to calculates the greyscale relativity of image template and matching image
the relativity of correspond location where match best with template will be most high
and in its neighbour range
the relativity will be still keep high too. We used these pixel in this local area of calculated match point to get sub-pixel accuracy
the relativity of every pixel be used as its weight for participate the sub-pixel calculation. The sub-pixel location is more accuracy than the integer one
we applied this method to perform background compensation in processing the target detecting for video image sequence. At the end of this paper
some experiment data be proposed
it proved this sub-pixel image correlation can obtain better result. 2011 SPIE.

In order to realize the aircraft attitude measurement
The paper advances electro-optical theodolite methods of measuring the aircraft attitude by using the spatial cosines relationship the single station theodolite and how to use intersection of the multi-station theodolite. The single station theodolite was introduced in a measured distance from the aircraft posture information. An exhaustive approach was used to access to the aircraft axis of the feature points and the location in the space was used to obtain space posture parameters. The multi-station theodolite was introduced to get the information of the aircraft flight attitude by method of using planes to the intersection. Two-dimensional image to obtain objective axis by fitting algorithm using Hough transform. And then
Calculate the vertical distance of the origin to the target of the central axis and the origin to the target of the central axis of the angle between the normal and the X-axis obtaining the linear equation in the two-dimensional plane. Two-dimensional axis of the target image and the camera system's optical center only identified a space plane. The aircraft yaw axis angle and pitch angle can be obtained by getting the space axis using plains to the intersection method. Experimental results show that attitude angle error of the single station theodolite is less than 1 when its distance is less than 6000m and attitude angle error of the multi-station theodolite is less than 0.6 when its intersection angle is between 30 and 150. In this paper
according to test result of precision comparing the mathematical model is correct and the algorithm is reasonable in extracting effective parameters of the aircraft's attitude. 2010 IEEE.

In order to match the intersectant targets' tab when these objects separate
a kind of method that makes use of fuzzy multi-parameter to match targets is proposed. Multi-parameters include the forecasted position after targets separate
target speed
target size and geometry shape
and different parameter corresponds to different influence coefficient
evaluate the integrated matching coefficient that every observation target corresponds to forecasted target
and the corresponding relationship that matching coefficient is the biggest is the best matching result. In order to locate the position and speed of forecasted target
a new method of track forecast is proposed
firstly
Hough transform is used to the object's track before objects intersect
by this
the object's positions that the warp between forecasted location and observation location is large enough is eliminated
then least square method is used for track forecast by the remainder valid positions
and get hold of the forecasted position when objects separate. The experiment results show: when tracking the bulky objects which intersect and separate
the right identification probability of traditional least square method is 87.5%
and the right identification probability of fuzzy match by multi-parameters can attain 96%
the reliability improves in evidence.
