A line-of-sight (LOS) Locating algorithm for staring imaging is presented in this paper. Staring imaging is an imaging mode for aerial remote sensor
which photographs the designated earth-fixed target in muItidirections. Therefore
the details of interesting targets is available. For the target obscured or disguised
its advantage becomes more apparent. This paper proposes the method using two-axis rotation to achieve staring imaging
and establishes the system model and the associated coordinates. Adopting the method of coordinate transformation
the LOS Locating algorithm is constructed
which determines the LOS direction. For the validation of algorithm
Target Geolocation Algorithm is established using Simulink library blocks. Eventually
it proves the feasibility of the LOS Locating algorithm. This article provides a thought of LOS Locating algorithm for staring imaging. The method of coordinate transformation used in this paper can be applied to line-of-sight positioning in other imaging modes. 2010 IEEE.

In order to improve the speed of matching algorithm and simplify the processing of existing sub-block coding matching
a new template matching method combined local gray value encoding matching and phase correlation is proposed. Matching process is divided into rough matching and fine matching. Rough matching divides the image into certain size blocks called R-block
sums the gray value of each R-block pixel
encodes the R-block according to the gray value distribution of R-block with the adjacent R-block
and matches by step between the template and each search sub-image. Then
fine matching results are obtained using phase correlation according to initial match parameters. The time complexity of the proposed method is (M2) .The new algorithm is faster than traditional algorithm by two orders of magnitude
and the speed has improved twice compared with existing sub-block coding method. Experiments demonstrate that the new algorithm is robust to the linear transformation of pixel grey value and image noise
and it also has the stability of small-angle rotation. 2009 IEEE.
