One way to precisely align is to place markers, or tags, around the site. We’ve designed “ChromaTag” (above) that can be detected more accurately and 10x to 50x faster than existing markers. The key is to encode the pattern for detection and identification within the “A” and “B” channels of the CIE L*a*b color space. Because the colors aren’t often seen next to each other in natural scenes, the tag can be detected very quickly, while detectors for colorless tags have to spend a lot of time sorting through t
The pilot will begin with a handful of graduating students—“we are targeting for the next batch,” says Choong—and once it proves successful, the school will extend it to the rest of the student body.
This project demonstrates how to use Apple’s Vision library to identify rectangles and model them in 3D using ARKit.
TL;DR: ARKit and Vision is an awesome combination.

At the SIGGRAPH Unreal Engine User Group on July 31, Epic gave the first public preview of the new workflow toolbox, Datasmith, and announced a private beta program. Developed to help artists and designers simplify the process of importing data into Unreal Engine, Datasmith initially supports more than 20 CAD and digital content creation sources, including Autodesk 3ds MAX. Other tools will become available as the beta program progresses.

ORB-SLAM is a versatile and accurate SLAM solution for Monocular, Stereo and RGB-D cameras. It is able to compute in real-time the camera trajectory and a sparse 3D reconstruction of the scene in a wide variety of environments, ranging from small hand-held sequences of a desk to a car driven around several city blocks. It is able to close large loops and perform global relocalisation in real-time and from wide baselines. It includes an automatic and robust initialization from planar and non-planar scenes. Demostrating videos, code and related publications are shown below.
