RFEL's Video Image Stabilisation IP Core is the first of its family of Video Processing IP cores that fully utilizes the power of the Xilinx Zynq-7000 All Programmable SoCs. The new stabilization IP Core is a high-performance video processing system that can readily support high input resolutions and frame rates, while maintaining low latency and power consumption. Stabilization is performed in real-time and entirely digitally, with the algorithm compensating for unwanted roll and horizontal and vertical shifts of a scene.
The stabilization Core is designed to deliver a stable image under the most demanding of applications, including: driving aids for military vehicles, diverse airborne platforms, targeting systems and remote border security cameras. The algorithm implemented within the IP core stabilizes images subjected to two-dimensional translations and rotations, from both static and moving platforms.
The stabilization function provides real-time correction at frame-rates of up to 150 Hz for various imaging devices, or for resolutions of up to 1080p including both daylight and infrared cameras. For example, a 1080p colour camera operating at 8 bits and with a frame-rate of 60 Hz, necessitates operation with an input data rate of ~1 Gbits/s. The accuracy of image stabilization, achieved when tested using a very diverse and demanding range of evaluation video data, has been shown to be better than ± 1 pixels, even when subjected to random frame-to frame displacements of up to ± 25 pixels in the x and y directions and with a frame-to-frame rotational variation of up to ± 5˚.
