In the application of mini - micro - robot visual perception, there is a need for fish - eye lenses for capturing wide field of view for navigation. though fish - eye lenses provide a wide field of view ( 180 ), they introduce significant distortion in images and the acquired images are quite warped, which makes conventional camera calibration algorithms no longer work well. this paper presents an accurate calibration framework for fish - eye lens ( a high distortion lens ) camera stereo vision system. the accurate calibration model is formulated with radial distortion, decentering distortion and thin prism distortion based on the fisheye deformation model. using fish - eye and non - linear camera model, the author employs levenberg - marquardt method to realize precise non - linear calibration for wide - view - scene dense depth image recovery
魚眼鏡頭成像立體視覺系統在微小型機器人視覺導航和近距離大視場物體識別與定位中有著廣泛的應用.盡管魚眼鏡頭攝像機具有很大的視場角(接近180 ) ,但同時也引入嚴重的圖像變形,常規的攝像機標定方法無法使用.該文提出一種標定魚眼鏡頭攝像機立體視覺系統的方法.在魚眼鏡頭變形模型的基礎上,通過考慮魚眼鏡頭成像的徑向變形、偏心變形和薄棱鏡變形,建立了魚眼鏡頭成像的精確成像模型,然後,利用非線性迭代演算法,精確求解攝像機外部參數、內部參數.實驗表明,使用該方法得到的立體視覺系統參數滿足精確恢復大場景稠密深度圖的要求With white background, the acquired images were studied. the distance was max between two - peak value in b gray level histogram. a set of computer vision hardware system which is use for bruise evaluation and classification of tomato was set up
通過大量的實驗研究,選擇環形燈作為光源,選擇白色作為背景組成光照箱,可以得到有利於后續處理的圖像;並發現在b分量上,兩峰間的距離最大,所以用b分量確定闡值t ;建立一套適合番茄等農產品進行表面缺陷自動檢測與分類的計算機視覺硬體系統。Aimed at static image retrieval based on color, a multimedia image database which included three layers was designed and the search algorithm of the correlation and polymerization histogram was used in the article. to show color characteristic of image, the method of the hsb ( hue, saturation, brightness ) color space, which is suitable to the visual characteristic of human, is utilized. taking advance of human ' s feeling to color, it quantifies color sector with unequal interval, and get characteristic vector
針對基於顏色的靜態圖像檢索,本文設計了一個三層的多媒體圖像數據庫,選用基於相關聚合直方圖的演算法,採用符合人類視覺特徵的hsb顏色空間來表示圖像的顏色特徵,利用人對顏色的感知來對顏色分量進行非等間隔的量化並形成特徵矢量,用距離度量函數進行圖像的相似性匹配。Multiple range images can be obtained by turning the 3d object at different angles around sensor. the range images of different viewpoints are registered to estimate the relative transformations among the viewpoints, and then integrated to obtain a complete 3d geometric description of object
本文採用相位法從多個不同的視點獲得距離圖像數據,通過多視點距離圖像的對準獲得視點之間的運動參數,然後經過距離圖像的集成,建立完整的物體表面的幾何形狀描述。In this paper, we first established the image metadata used in our system which based on the famous dublin core, then we analyzed the abstraction and description visual features of image such as color texture and shape. next, we discussed the problem of similarity measure of visual feature, imported fuzzy logic into the distance feature and pointed out the disadvantages of geometry space based methods. for multi - dimension vector ' s high dimension nature, it ' s hard to index with traditional methods, we discussed how to lower the dimension using clustering and klt transformation
