We have a highly sophisticated light sheet imaging system that produces images with nonlinear distortion. The usual radial distortion correction methods don't work. So, we modeled the distortion by imaging a uniform grid and modeling the distortion using 4th order Bezier Surface patches.
Steps Involved:
- Apply Homography
- Find corners
- Find corresponding points
- Model the displacement using bezier curves and create a linear system of Equations
- Solve the system of equations
- Correct using the modeled deformation
