A new method for obtaining facade image of building by using fish - eye lens
魚眼鏡頭在獲取建築物立面影像中的新方法 -
Because of the aberration of fish eye lens resulting from fabrication procedure, there exists serious geometrical distortion, which arises the problem of correcting the fish eye image
由於魚眼鏡頭製造過程中產生的誤差等原因，所拍攝的圖像幾何畸變還是比較嚴重的，這就產生了對魚眼圖像進行幾何校正的問題。 -
In creation of spherical panoramic, the technique using fish - eye lens to capture image is briefly studied, and the technique using digital camera is studied in detail. in the latter technique, spherical image mosaic is a key problem
在球面全景圖生成方面，本文對使用魚眼鏡頭的技術作了簡單的介紹，重點討論了使用普通數字相機的球面全景圖生成技術。 -
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
