Researching to Edge Detecting and Locating of Aero Craft Down-view Image
飞行器下视景像边缘提取和定位方法研究

To reduce the influence of geometrical deformation on image matching,we put forward a method which can detect multi-pixels edge of image.The method is based on difference of gray-level between the border upon pixels.Adopting matching method of multi-pixels edge,matching between datum image and real-time image is improved observably because of deformation,such as edge excursion,rotate and scale transformation.The result show that,the multi-pixels edge detecting and matching method is of simple model,perfect real-time quality and power ability to counteract the effect of geometrical deformation.The whole system can be realized easily.
