What is tangential distortion?
In most cameras used for robotics or automated vehicle applications, tangential distortion will usually be significant enough to model, but is often an order of magnitude smaller than e.g. symmetric radial distortion. Example of a compound distortion profile, which combines barrel, pincushion, and tangential effects.
Do cameras have tangential distortion?
Note that here the effect is exaggerated, most cameras do not have tangential distortions to this degree. Tangential distortion is sometimes also called de-centering distortion, because the primary cause is due to the lens assembly not being centered over and parallel to the image plane.
What is the decentering distortion model?
This distortion model is also known as the "Brown-Conrady model". , 79:384-390, 1919. The very first introduction of the decentering distortion model. The tangential distortion is due to imperfect center ing (“decentering”) of the lens components and other manufacturing defects in a compound lens.
How does lens geometry affect tangential distortion?
Example of lens geometry as it impacts tangential distortion. In the top graphic, the lens is not parallel with the image plane, which produces tangential distortion. In the lower graphic, the lens is offset from the image plane.
