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 the paper, the load incremental method is adopted. by the way of reducing the elastic model of the destructive blocks in the elements, the finite element analysis model is revised and the repeated computing process does n ' t finish until the results are converged. the proposed method can simulate the entire process of concrete structures from crack to complete damage
分析中採用載荷增量法，對各級載荷下單元中破壞的材料分塊進行彈模折減處理，並重新生成單元剛度矩陣，經過多次迭代直至計算收斂，從而可以給出各類cfrp加固混凝土結構的載荷?變形全過程曲線，並預測其極限承載力。According to the basis relation of stress, strain and the value of limit deformation during the strengthening of concrete architecture, the derivate computing method is applied under different state of load and internal force. and it is towards difference of stress and strain of the new and old part of the strengthening structure. it is pointed out that unloading is the necessary and important method of taking advantage of effect of the strengthening structure
本文根據混凝土結構加固中材料的基本應力? ?應變關系和極限變形值，針對加固結構新舊兩部分的應力、應變差，應用迭加原理，導出了加固結構在不同受力狀態下的承載力和內力適用設計計算方法，指出了「卸荷」是充分發揮加固結構效能的必不可少的重要手段。This paper is devoted to seeking formulas and rules of representation for generating new fractal graphics. the main works are as followed : ( l ) construct new formulas for new fractal aspects after revisited methods for the visualisation of mandelbrot and julia sets based on ifs, we described the other new formulas originating from z z2 + c. including norton and polynomials iterated function, which have integer index instead quadratic index, we also constructed formulas with complex number index. 3 - d dynamical system is discussed then. besides the most widely used sequential visualisation methods, we designed two methods to change the original vectors and get new graphics with special effects
