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

It can be concluded that the performance differences between the plate membrane and the hollow fiber membrane can be attribute to difference of the stresses in the membranes when they were under pressure and the difference of the strain caused in the membrane, besides the possible reason that the surface curvature difference between a plate substrate and a hollow fiber one may cause structure difference in the dense functional layer when coating. the stresses in a hollow fiber composite membrane under an outside pressure are quite different from that in a plate one in that they exert on the hollow fiber in both the radial and circular directions, and the compress strain of the hollow fiber is thus much more complex, which may cause the top layer crinkle and a decreased salt rejection
