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(yú)眼鏡頭成像立體視覺(jué)系統(tǒng)在微小型機(jī)器人視覺(jué)導(dǎo)航和近距離大視場(chǎng)物體識(shí)別與定位中有著廣泛的應(yīng)用.盡管魚(yú)眼鏡頭攝像機(jī)具有很大的視場(chǎng)角(接近180 ) ，但同時(shí)也引入嚴(yán)重的圖像變形，常規(guī)的攝像機(jī)標(biāo)定方法無(wú)法使用.該文提出一種標(biāo)定魚(yú)眼鏡頭攝像機(jī)立體視覺(jué)系統(tǒng)的方法.在魚(yú)眼鏡頭變形模型的基礎(chǔ)上，通過(guò)考慮魚(yú)眼鏡頭成像的徑向變形、偏心變形和薄棱鏡變形，建立了魚(yú)眼鏡頭成像的精確成像模型,然后，利用非線性迭代算法，精確求解攝像機(jī)外部參數(shù)、內(nèi)部參數(shù).實(shí)驗(yàn)表明，使用該方法得到的立體視覺(jué)系統(tǒng)參數(shù)滿足精確恢復(fù)大場(chǎng)景稠密深度圖的要求
