In allusion to the character of aircraft orientation error in inertial navigation system increasing with its working time and error accumulation
airborne image aided navigation system is imported in inertial navigation system to combine integrated navigation system. To acquire high orientation accuracy and high matching speed a new algorithm based on multi-scale edge detection and generalized point theory is put forward. At first multi-scale edge detection algorithm is adopted to realize airborne image edge detection
then image matching algorithm is used based on generalized point theory is used to eliminate error accumulation of peg-top excursion and accelerometer error to correction aircraft aircraft pose error to increase navigation accuracy of aircraft. To prove the algorithm is effective and robust
simulative experiment is done. The simulative experiment indicated that aircraft orientation accuracy is better than inertial navigation system
and its orientation error is less than 15 meters after airborne image aided navigation correction. 2010 IEEE.

On aviation mapping
compression image maybe not decode because of wireless transmission interference. UEP(Unequal Error Protection) scheme is put forward about layer and block structure of JPEG2000 image compression method
flexibly enhances local reconfigurable image's quality which is in favor of identifier in the region of interest. 2008 IEEE.
and realizes three degrees UEP of data block
data header
image data via various degrees correction-coding under the condition of obstruct
naked and shade. BCH
RS and Hamming coding are simulated
and image decoding success rate and image's quality are analyzed according to different coding and ROI (Region of Interest) in the Gaussian white noise model and rayleigh fading model. Results shows that the method we putted forward roughly improves decoding success rate
