  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

    魚眼頭成像立體覺系統在微小型機器人覺導航和近距離大體識別與定位中有著廣泛的應用.盡管魚眼頭攝像機具有很大的角(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頭攝像機立體覺系統的方法.在魚眼頭變形模型的基礎上,通過考慮魚眼頭成像的徑向變形、偏心變形和薄棱變形,建立了魚眼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,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
  2. ( 1 ) an optical technique is presented to quantify the creep crazing damage in stressed transparent glassy polymeric sheet of pmma. craze area density in this article is defined by ratio of crazing area and the overall area of the region selected. the specimens were loaded for a defined period of time under creep condition with room temperature, by optical microscope the evolvement of craze density varying with stress and time is obtained

    Pmma ( polymethylmethacrylate )是一類重要的高聚材料,在應用上屬于用量大、使用范圍廣的一類通用材料,本文選用pmma為主要研究對象,主要研究成果如下: ( 1 )用顯微對透玻璃態材料pmma蠕變條件下的銀紋損傷引發和演化進行了實驗觀測,將銀紋所佔面積和所取圖象總面積的比值定義為銀紋密度,得到了銀紋密度隨時間和應力變化的演化方程。
