Because the air - borne imaging system is required a far acting distance and the focal length of its optical system is long. influenced by the unsteady or moving platform mounted on plane, the change between the frames of image sequence is more. problems of image fuzziness and instability tend to be striking out, which becomes a bottleneck restricting the air - borne reconnaissance, collimation, evaluating beat effect
機載光電成像系統,由於要求作用距離遠,故其光學系統焦距長,受其載體姿態變化和振動的影響,圖像序列幀間變化過大,造成觀察者覺得模糊、不穩定,己成為制約空中偵察、瞄準、打擊效果評估等功能的瓶頸。In the method dfd ( depth from defocus ), feasibilities of restoring images from defocus images and estimating the focused position are discussed and confirmed
離焦深度法估計離焦距離或者進行圖像恢復的依據是成像系統的點擴散函數及它所產生的模糊圓。Firstly, basic theories and methods of autofocus based on image processing are studied in detail

摘要介紹了一種新型的自動調焦的方法,它利用電視跟蹤系統視頻信號的峰值變化控制調焦鏡組,來調整由於目標距離、溫度等變化引起的成像焦面變化,得到清晰圖像,完成電視自動調焦。The limitations of current video technology, however, mean that the quality of the visual experience of the real world is significantly decreased, essentially to the level of the synthesized graphics, with everything focusing at the same apparent distance
然而,現有視訊技術仍有其限制,它所呈現的真實世界的視覺品質還相當差,甚至會降到合成圖像的水準,因為虛擬和實體的所有視覺焦點都在相同距離上。The experiment results show that there are optimal defocus distance and exposure for the given system and recording material, and to obtain the best snr different reference - to - object beam ratios are also needed for black - white digital images of different space frequencies
實驗結果表明,對于給定的系統及記錄介質存在一定的最佳離焦量和曝光量,而對于不同空間頻率的黑白二值條紋圖像還需要採用不同參?物光比以最終獲得最佳的信噪比。Multi - focus image fusion based on wavelet transform and local dispersion
基於小波變換與局部離散度的多聚焦圖像融合演算法Experimentally, the plasma produced by cable plasma gun ( c - gun ) and dense plasma focus ( dpf ) was measured by the laser differential interferometer system. the clear interference patterns were acquired at different time. the contour maps of line integral density and curves of radial local density at different height above nozzle were presented
實驗上,對等離子體斷路開關中的電纜等離子體槍( c - gun )和等離子體焦點裝置( dpf )產生的等離子體進行了測量,獲得了對應不同時刻的清晰的干涉圖像,給出了線積分密度等值線圖和距噴口不同高度處的徑向密度分佈。Geometric distortion is traditionally corrected by an image resampling operation which is applied as a post - processing step to pfa. the scene size limits of pfa presented by range curvature qpe, can be alleviated by using an efficient image domain space - vairant post - filter
通常採用圖像域插值的方法校正幾何失真,而利用空變濾波器使散焦的點重新聚焦,這些校正方法可以減輕距離彎曲對成像范圍的限制。Furthermore, a new dfd method was put forward. the method estimated the focused field through analyzing three images at different lens positions and then found best imaging position within the field in small steps
同時,本文提出一種逐漸逼近的離焦深度法,先通過少量對焦位置不同的圖像計算出近似準焦位置,再用小步長在其附近搜索最佳位置。2. not only made a details description of distort - image recovery methods including out - of - focus, motion - image and geometrical - transformation, but also realize the recovery function under the environment of visual c + + and matalb. this application is also an innovation in the image processing technology
由於失真的原因多種多樣,本論文將詳細地介紹離焦、運動這兩種主要失真圖像的復原方法,並且將利用vc + +語言和matlab語言結合起來實現這一功能。Finally, the automatic opto - electronical hybrid joint transform correlator was set up, which produced a quite good recognition result for both binarized image and complicated grayscale - level images. this paper also discussed the effects of lctv on jps
