Lens Distortion Modeling: Coefficient Selection and Tangential Distortion Considerations

This study investigates the sufficiency of two radial coefficients and two tangential coefficients in modeling lens distortion and examines the impact of neglecting tangential distortion while increasing the number of coefficients. The results are obtained using various lenses and cameras, including the Nikon 14mm f/2.8D Ultra Wide Angle Nikkor Lens. Visit amazon.com for more details. Results are compared using AIC Criterion, MDL Criterion, BIC Criterion, SSD Criterion, and CAIC Criterion.

  1. Model Selection Results with Real Data Vitaliy Orekhov Imaging, Robotics, & Intelligent Systems Laboratory The University of Tennessee

  2. Distortion Model Selection Are two radial coefficients and two tangential coefficients sufficient to model the lens distortion? Should tangential distortion be ignored while increasing the number of coefficient used to model radial distortion? NIKON 14MM f/2.8D Ultra Wide Angle Nikkor Lens www.amazon.com Tamron 28-300mm Lens

  3. RDDD and LPDD Model Results (1) 300mm Nikon Vari-focal Lens, (2) PULNiX CCD camera with 6mm lens, (3) IQEye3 with a FUJINON 1.4-3.1 mm lens set to wide angle, and a Nikon fisheye FC-E8 lens set to two different zoom settings to produce a (4) full frame fisheye (FOV of 180° across the diagonal) and (5) circular fisheye (FOV of 180° in all directions)
