Fisheye Lens Geometric Correction

This is a MATLAB-based fisheye lens geometric correction program designed to transform images captured with fisheye lenses into normal perspective images. The program implements sophisticated correction algorithms to eliminate distortion caused by fisheye lenses, making image observation and analysis more accurate and convenient. Fisheye lenses are ultra-wide-angle lenses capable of capturing over 180 degrees of field of view. However, due to their unique optical structure, fisheye lenses introduce significant curvature and distortion issues in captured images. This program performs geometric correction using coordinate transformation techniques and distortion parameter estimation to restore images to their natural, realistic appearance. The implementation typically involves camera calibration, distortion coefficient calculation, and image remapping functions available in MATLAB's Computer Vision Toolbox. This solution finds extensive applications across various domains including computer vision systems, robotics navigation, virtual reality environments, and surveillance systems. By utilizing this program, researchers and engineers can effectively process and analyze fisheye images, significantly improving work efficiency and analytical accuracy in vision-based applications.
