Perspective Transformation and Lens Correction Image Processor

The logiVIEW Perspective Transformation and Lens Correction Image Processor IP core for video and imaging applications using single or multiple camera imagers removes fish eye distortions caused by extreme wide-angle field of view (FOV) lenses, makes perspective corrections to the captured video and stitches multiple corrected video inputs in a resulting single image for the LCD display. The logiVIEW corrects multiple 30 fps or higher frame rate video inputs in real-time. The provided calibration software, with the included preview option, speeds up IP adoptions to different camera imagers and camera system setups.

The logiVIEW IP core can be used in different industries and applications like, i.e. medical endoscopy, pipe inspection, surveillance, automotive surround view driver assistance systems, defense, etc.

The logiVIEW IP core is the key IP core in the logiVIEW-SVK Development Platform and Toolset for automotive designers of Surround View Driver Assistance (DA) Systems.
