Abstract
An efficient pipelined architecture for the real-time correction of barrel distortion in wide-angle camera images is presented in this paper. The distortion correction model is based on least-squares estimation to correct the nonlinear distortion in images. The model parameters include the expanded/corrected image size, the back-mapping coefficients, distortion center, and corrected center. The coordinate rotation digital computer (CORDIC) based hardware design is suitable for an input image size of 1028×1028 pixels and is pipelined to operate at a clock frequency of 40 MHz. The VLSI system will facilitate the use of a dedicated hardware that could be mounted along with the camera unit.
