Multiview 3D Video Transformation Engine

Available New Version of the logiVIEW Multiview 3D Video Transformation

November 3, 2020, Zagreb (Croatia) – Xylon announces a new and updated version of the company’s very successful logicBRICKS IP core, the logiVIEW Multiview 3D Video Transformation Engine for high-performance and real-time processing of multiple video streams or still images in embedded systems. The logiVIEW IP core is optimized for Xilinx® programmable devices, and can be used in very cost effective Xilinx SoC and MPSoC devices to support versatile multi-camera video and vision applications.

Each of the logiVIEW’s up to eight independent video channels can be configured to remove fisheye distortions caused by extreme wide angle Field of View (FOV) lenses, and to make an arbitrary combination of complex homographic transformations, including perspective corrections. Moreover, each video channel can execute any complex non-homographic transformation defined by Memory Look-Up Tables (MLUT), such as video texturing on curved planes.

The logiVIEW IP is a key part of Xylon’s ViewMore™ Natural Surround View parking assistance solution, which enables drivers to dynamically adjust the position of the virtual flying camera, and to see the vehicle’s natural-looking surroundings in a three-dimensional hemispheric view displayed in fine-detail HD resolution. With Xylon’s complete IP and software suite, automakers and their electronics suppliers can create their own differentiated and scalable parking assistance, and combine it with other Advanced Driver Assistance Systems (ADAS) functions within the same Xilinx programmable chip.



Thanks to the logiVIEW IP core’s latest improvements, such as the ability to dynamically change video projection planes (3D hemispheric view, “the bowl”) for reduced perspective distortions (“Manhattan” effect), and the equalized multi-camera brightness under changing illumination conditions, Xylon's complete Surround View solution now offers more natural-looking 3D views of the vehicle's surroundings. Additionally, it enables a dynamic change of stitching lines between the neighboring video cameras, and a detailed view of distorted or hidden objects within their overlapping fields that might be discovered with other automotive sensors, like ultrasonic or LIDAR sensors.
