or Perspective Correcti ye Distorted Images
Sachin Bang, Smita K. Nair, Krishnan K. Kutty · 2011
Fisheye cameras are widely applications like surveillance, robotic vision, view imaging systems etc. But the images captu are hemispherical and objects away from th look curved due to lens distortion. Hence it is end user to interpret the data correctly from solution lies in digitally processing these distortion-free rectilinear images. The process for both fish eye and perspective distortio overhead. This paper presents a novel approach that co perspective distortions from wide angle camer geometry of hyperbola is used for fisheye perspective correction is done using a stan based transform. Both these correction techni to form a mapping matrix wherein each o corrected image is related to the correspondin distorted image. This approach using a mapp the overall processing time and hence can be correction. This method finds application in vi assist system; in order to provide a perspe parking area from the input wide angle images
