WebFeb 1, 2008 · Thin prism distortion arises from slight tilt of lens or image sensor array and also causes additional radial and tangential distortion [1], [2], [5]. Here we can see that the radial distortion, decentering distortion and thin prism distortion are coupled with one another, because both decentering distortion and thin prism distortion have a ...
By using a lens we get better quality images but the lens introduces some distortion effects. There are two major types of distortion effects : 1. Radial distortion: This type of distortion usually occur due unequal bending of light. The rays bend more near the edges of the lens than the rays near the centre of the lens.
