Video Stitch Xilinx FPGA IP

The Omnitek Video Stitch IP is a highly configurable and optimised FPGA IP Core for real time image stitching of up to 8 video streams into a single 4K / UHD video stream. The Video Stitch IP employs FPGA hardware to perform real time image stitching using image coordinates calculated using software running on the FPGA CPU.

Reference frames are captured at regular intervals from the live video streams and the CPU calculates the overlap and individual warps that need to be applied to the images to correctly stitch them together.

The Video Stitch IP can be used with the range Omnitek’s Rx IP including the SDI IP, HDMI IP, “DisplayPort”, “LVDS”, etc. and can be used with Omnitek’s Image Signal Processing IP (to process the RAW sensor images) and Omnitek’s HDR Tone-mapping IP (to improve image dynamic range and contrast).

In this example, multiple RAW camera images are being processed by multiple instances of the ISP IP, enhanced by corresponding HDR Tone-mapping IP and then stitched together as quadrant display by the Image Stitch IP. The Warp Processor within the Image Stitch IP will intelligently stitch together the four source images and make the appropriate geometric and colour corrections to produce a composite image.

The Video Stitch IP can be configured to stitch together up to 8 camera images to produce a panoramic or 360 degree display.
