Fisheye_correction_algorithm

Introduction

This project implemented 4 algorithms for fisheye corrections. Running environment: matlab.

• Spherical_coordinates.m:2D spherical coordinates algorithm

• Spherical_perspective_projection.m：spherical perspective projection algorithm

• fish_2D.m: 2D stereoscopic projection coordinate transformation (spherical projection model)

• fish_correction.m, fish_3D_origin.m: Display correction of spherical perspective projection model based on the fish-eye image is divided into left and right and up and down the center of five grid

Outcome

This work has been implemented in the FPGA DE2-115.

• Paper: [A Fisheye Lens 360 Degree Panoramic Monitorin System Based on the FPGA] (http://www.innovateasia.com/asia/download/articles/2013/cn069.pdf)
