In order to meet requirement of real-time and high accuracy in image matching aided navigation
SSDA algorithm is used to match remote sensing image and template image coarsely
a fast and effective algorithm of remote sensing image matching based on corner detection is put forward. With the combination of rough and fine match
when the matching result is bigger than one to count absolute value sum of energy difference of characteristic point energy to realize fine match of remote sensing image and template image to locate the position of template image in remote sensing image accurately. Simulation experiment proves that the matching of a remote sensing image resolution of 1018*1530 and a template image resolution of 150*90 can be fulfilled within 2.392 second
wavelet transform is used to acquire low frequency component to realize image compression to decrease calculation work and increase matching speed. Harris corner detection algorithm is used to detect corner of remote sensing image and template image and energy of every corner is calculated
the algorithm is robust and effective
real time image navigation can be achieved. 2009 SPIE.

Transmit array photogrammetric camera can obtain image which is high geometric fidelity and high photogrammetric quality. However
the single chip array CCD image sensor camera can't meet the need of measuring precision and photogrammetric covering area. In order to obtain large numbers of information and extensive photogrammetric covering area
we must increase field of vision angle and improve photogrammetric covering area. And all these objects can be realized by exterior field of vision assembling photogrammetric camera. Two side work must be done before images
which obtained by exterior field of vision assembling photogrammetric camera
be used in photogrammetry. First
all assembling camera focal plane need be converted to a benchmark coordinate focal plane to realize camera digital assembling. Second
images must be re-sampled and processing. Because of coordinate conversion
two images from different assembling cameras can be established function relation
which a pixel of image from a camera is corresponding to a pixel of another image from different camera. But through this conversion
some pixels maybe extrusion together and other pixels separate on an image area. So interpolation direction finding(IDF) is used to obtain these pixels and realize image re-sampling. In this paper
the structure of exterior field of vision assembling photogrammetric camera is analyzed
and the coordinate conversion method of exterior field of vision assembling photogrammetric camera and image gray re-sampling method also can be discussed. All the works are based to data pretreatment of exterior vision assembling photogrammetric camera.
