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.

After analyzing advantages and disadvantages of these typical encoding methods: SPIHT and VQ
a "DWT+MRLE" approach for spaceborne data compression was proposed in this paper. This approach includes two steps: Discrete Wavelet Transform (DWT) and Modified Run Length Encoding (MRLE). The former used CDF9/7 biorthogonal wavelet filters to powerfully get rid of correlation between pixels in imagery. The later put enlightening information into the lowest bit of some key-position transform coefficients. Consequently
CDF9/7 and MRLE together make hardware platform remain high real-time capability
and help reconstructed images keep good fidelity with PSNR being about 40dB
compared with the original ones. Comparison between experimentations on SPOT4's low-spatial-resolution (10m) imagery and Ikonos2's high-spatial-resolution (1m) imagery
shows this "DWT+MRLE" method having better performance for remote-sensed imagery
especially those of higher resolution. Although inferior to 8:1
Compression Ration (CR) here near 5:1 is greater than France SPOT5's 3:1 and American Ikonos2's 11:2.6 on-board data compression. More important
this method having less computational amount is good for spaceborne capability of real time. The consumed time of different image size is also presented in this paper
based on TI TMSC6416 DSP chip with 600MHz CPU cycle clock.
