IP corrects for fish eye distortions

Dec. 6, 2012
Engineers at Xylon (Zagreb, Croatia) have developed an IP core to process multiple still images or video streams in real time to remove fish eye distortions caused by extreme wide-angle field of view  lenses.

Engineers at Xylon (Zagreb, Croatia) have developed an IP core to process multiple still images or video streams in real time to remove fish eye distortions caused by extreme wide-angle field of view lenses.

The company believes that one application where the new so-called logiVIEW IP might find a home is in surround view driver assistance systems that use at least four cameras equipped with extreme wide-angle fish eye lenses, which cover separated zones around the vehicle.

Here, the logiVIEW IP could be put to use to remove the lens distortions from the cameras and stitch the corrected video images together to produce a single image of vehicle’s surroundings.

The company says that the logiVIEW IP core itself can be implemented in on a Xilinx Zynq-7000 SoC and FPGAs where it can be interfaced to an Arm Coretex, Xilinx MicroBlaze or PowerPC CPU.

Complete details of the IP, including more examples of where it might be used, can be found on the Xylon web site here.
