  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
  2. The space observation in soft x - ray and extreme ultraviolet ( euv ) region is an important portion of the space astronomy and an effective solar observation method developed increasingly. in this thesis we designed a euv multi spectrum space solar telescope ( eut ) based on the requirement of high angular resolution and wide field of view for solar observations ; investigated the transmission performance of eut ; invented a method of eut pointing calibration on the space orbit and solved the high precision pointing calibration problems ; constructed a prototype of 17. 1nm telescope, tested the possibility of eut design, and developed some cutting - edge techniques

    本文根據空間平臺上高解析度對日觀測的需要,設計出一種可以在四個極紫外波段對日同時成像多光譜太陽望遠鏡( eut ) ;研究了極紫外( euv )波段太陽望遠鏡光學傳輸特性;提出了真空紫外波段在軌指向的標定方法,解決了高精度指向標定問題;研製出一臺17 . 1nm望遠鏡的地面樣機,驗證eut設計的可行性,攻克了部分關鍵的技術難關;為進一步的研究工作奠定了基礎。
