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 -
In order to meet the needs of this application, we propose several approaches to compute reliable dense depth maps, such as a feature - constrained stereo matching algorithm, a stereo matching algorithm based on gray segments and a stereo matching algorithm based on fuzzy identification, we demonstrate these techniques on synthetic and real image pairs, indicating that these approaches are feasible
圖像深度提取一直是計算機視覺領域的中心研究問題，為了得到圖像繪制系統必需的比較精確的高密度深度圖像，我們相繼提出了基於特徵約束的立體匹配演算法、基於灰度段的立體匹配演算法和基於模糊判別的立體匹配演算法，通過實驗驗證上述三種演算法均獲得了良好的效果。 -
It was showed that dlc gradient film material had a good stability of hemocompatibility, for its surface almost had no changes. in comparison, the hemocompatibility of t16a14v became worse since its surface had been heavily scratched and dense oxide films on its surface had been destroyed. fratal theory and image processing method had been applied to calculate the fratal dimension of tribological surfaces furthermore to elavuate the surface morphology and roughness
