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.

In this paper  we propose a novel method that combines improved chain codes based edge tracking (ICCBET) with Hough transform (HT) to successfully detect the airport runway in real time. ICCBET primarily removes the short and curving lines to reduce the pixels and confirms the approximate orientation to shorten the angle range HTprocesses in later. Furthermore  through using pyramid during HT stage  the computation cost is reduced considerably to satisfy real time performance. Finally  we fix the memory by designing a chain list array for the image to avoid overflow arise from building chain list with memory dynamic allocation. Experiments on various images show that our method satisfies the real time need with about 23.5 multiples computation reduction contrast to the original Hough transform (OHT) and overcomes the blur to localize the lines with high accuracy contrast to the original chain codes based edge tracking (OCCBET). 2008 IEEE.

In this paper  the time of feature extraction is faster. By test in low contrast image  2D continues Gabor wavelets are adopted to realize feature extraction. By optimize Gabor wavelet's parameters of translation  the feasibility and effectiveness of the algorithm are demonstrated by VC++ simulation platform in experiments. 2004 IEEE.  orientation  and scale to make it approximates a local image contour region. The method of Sobel edge detection is used to get the initial position and orientation value of optimization in order to improve the convergence speed. In the wavelet characteristic space  we adopt PSO (particle swarm optimization) Algorithm to identify points on the security border of the system. Comparing to the LM algorithm  it can ensure reliable convergence the target  which can improve convergent speed
