  1. 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

    魚眼成像立體覺系統在微小型機器人覺導航和近距離大物體識別與定位中有著廣泛的應用.盡管魚眼攝像機具有很大的(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攝像機立體覺系統的方法.在魚眼變形模型的基礎上,通過考慮魚眼成像的徑向變形、偏心變形和薄棱變形,建立了魚眼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覺系統參數滿足精確恢復大景稠密深度圖的要求
