碩士 / 國立中興大學 / 土木工程學系所 / 98 / 3D information can be obtained from the images taken by a general digital camera, since the development of 3D information extracting technology from a 2D image. However, a conventional camera has a limited viewing aspect that is a barrier to acquire a wide range image from a short distance. For wide scenes imaging with a single camera, one solution is to adopt a camera with fish-eye lens. In this study, a MATLAB toolbox was employed to calibrate Ladybug’s fish-eye lens camera with an average of error less than 0.5 pixels. The transferring model was developed by applying Taylor’s series to simulate the image projection function. Assuming that all the contour lines of the object parallel to axes and giving the distance between the camera and the object, the transferring model is able to calculate 3D coordinates of objects accurately and describe the shape of the object.
