Effect of microscanning on spatial resolution 微掃描對空間分辨率的影響
From the result of simulation through computer the technique of microscanning can effectively reduce the aliasing effect and improve the final resolution of the image 通過理論和計算機仿真分析可知,微掃描能有效的減小頻譜混淆,提高圖像分辨率。
Due to the fact technique of microscanning makes use of the compensative information between each single image with different order , the information of the original image can be recovered very well 由于微掃描利用了同一景象的序列圖像之間不同卻相互補充的信息,可以更好的重建原始圖像。
In this paper the theory of microscanning is described and the process of imaging of microscanning is simulated theoretically , meantime , the possibility of improving the quality of image using microscanning is deduced from the sampling theorem 詳細介紹了微掃描的原理,并對微掃描的成像過程進行理論建模,從抽樣定理推論出采用微掃描技術(shù)對改善圖像質(zhì)量的可能性。
The difference between the image obtained through method of microscanning and the single sampling image is simulated by computer based on the theory of microscanning . the sampled image and the images constructed with microscanning are presented as well 用計算機進行仿真分析,比較了采用微掃描方法合成的圖像和單幀抽樣圖像的差異,并給出了填充因子不同時的抽樣圖像和微掃描重建圖像。
Due to the fact that the properties of infrared detector array ca n ' t be satisfied to produce a image with high resolution because of the level of manufacture , the phenomenon of subsampling and serious aliasing emerges . in order to reduce these phenomenon and improve the image resolution the technique of microscanning is introduced 紅外探測器陣列由于受到工藝水平的限制,不能制成用于產(chǎn)生高分辨率紅外圖像所要求的密度,一般會產(chǎn)生空間欠抽樣圖像,圖像中有嚴重的混淆現(xiàn)象,為了減小這種混淆、提高分辨率,引入微掃描技術(shù)。
百科解釋
Microscanning is a method for increasing resolution of digital cameras. With the color co-site sampling identically colored pixels in several frames of the specimen, obtained by moving the sensor with a piezo mechanism in a regular raster, are combined to a sharp resulting image.
