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The tactical missile seeker handover accuracy from midcourse to terminal guidance is researched. the small perturbation method is proposed to analyse error sensitivity of the seeker presetting parameters from error sources. firstly, the terminal guidance seeker presetting parameters are computed, based on the equations of a surface - to - air missile movement and a target movement. then the seeker presetting unaccuracy due to the command guidance radar measurement errors is also computed. it can be seen that the seeker presetting errors increase rapidly when the missile is close to the target, which leads to an important conclusion that the late seeker handover from midcourse to teminal guidance should be avoided
