Wide Angle Distortion Correction in Fisheye Images

Eknath Salvi, Shrddhey Jain, Priyanka Ranade

Abstract


In today’s imaging system Enhancement and improvisation has been developed wisely such a way that there is lots of scope to have better applications with the improved results. There are many applications such as Automobile system, surveillance system etc where the image improvisation and enhancement has wide scope. The Normal camera can capture image but with the smaller angle of view on the other hand if we use the fisheye lens camera then the view of the image is wider and have large FoV (Field of View). It gives the wider view but at the cost of distortion. So image captured by these cameras exhibits the distortion which creates problems in many applications such as object detection, surveillance, Automobile Systems. The methodology discussed in the proposed work will help to reduce such distortion occurred due to fisheye lenses so that FoV of the camera will increase.
