MATLAB Program for Unfolding Fisheye Images into Cylindrical Images with Code Implementation Details

In this documentation, we will discuss how to develop a MATLAB program that transforms fisheye images into cylindrical projections. To achieve this objective, we will explore fundamental image processing techniques and algorithms, demonstrating their implementation within the MATLAB environment. The program involves coordinate system transformations where fisheye distortion parameters are calculated using trigonometric functions to map spherical coordinates to cylindrical surfaces. Key MATLAB functions such as imread() for image input, meshgrid() for coordinate generation, and interp2() for interpolation play crucial roles in the transformation process. Through this program, we can enhance our understanding of fisheye image processing and effectively convert them into cylindrical images for improved subsequent analysis and applications. The implementation typically includes steps for calibration parameter estimation, pixel remapping using backward transformation, and bilinear interpolation for smooth output generation.
