Description
Experience Level: Intermediate
Reality7 is a hard & software company that develops a one stop solution for professional stereoscopic 360° video production. On the hardware side we have a camera with 17 industrial grade cameras set up in an array as seen in the designs/drawings
(https://github.com/facebook/Surround360/tree/master/surround360_design). On the software side we have a capturing and render software. In order to have a ground truth to test our render system we need a 3dsmax file that has an outside and inside environment with 17 cameras mapped in the exact same way as seen in the above-mentioned designs. Therefore, if we render all photos of all 17 cameras we should be able to use these rendered images to render a stereoscopic 360° image with our render software. The 3dsmax file basically replaces our capture software and hardware so that we can create a ground truth for our render software.
In order for this to work you need to map exactly the same camera and lens specifications as described in the above-mentioned designs. The 14 cameras in the horizontal ring uses GS3-U3-41C6C-C
Point Grey cameras (https://www.ptgrey.com/grasshopper3-41-mp-color-usb3-vision-cmosis-cmv4000-2-camera). Please make an account at point grey in order to see all the specifications. The 14 horizontal cameras use wide-angle lenses (http://www.optics-online.com/OOL/DSL/DSL318.PDF) that can be mapped in in 3dsmax. The top and bottom cameras also use the same point grey camera but use this fisheye lens;
(http://www.fujifilm.com/products/optical_devices/pdf/cctv/fa/fisheye/fe185c086ha-1.pdf). This is the most difficult task as there is no possibility of mapping a fisheye in 3dsmax. This has to be modelled – or if some plugin exists please let us know. Just to clarify, we do not need a 3ds model of the cameras/cameras setup. We only need the 17 cameras placed and mapped in the exact same way as they are setup in the above-mentioned designs.
For the indoor and outdoor environment, you can use an existing one or download from the Internet. We just need two different scenes. It is important that there are no close objects to the camera. A minimum distance between an object and the camera of 2 meters in needed. From two meters to 10 meters there should be many objects so that our render system is able to detect features in the rendered 3dsmax images.
If you have any questions regarding the task, please do not hesitate to ask any questions.

Grasshopper3 4.1 MP Color USB3 Vision (CMOSIS CMV4000-3E5)
The high performance Grasshopper3 camera line combines the benefits of CCD with the affordability and data throughput of USB 3.1. Its FPGA and frame buffer-based architecture provides optimal reliability, a rich set of features, and a full image processing pipeline including color interpolation, gamma, and lookup table functionality. The Grasshopper3 offers a powerful, easy-to-use, and cost-effective alternative to Camera Link and dual GigE LAG solutions.
