•
1 gefällt mir•324 views
If you think there's been a lot of talk about Augmented Reality and Virtual Reality this year, 2018 is going to blow you away. Apple with ARkit, Google with ARCore , Microsoft with HoloLens, Facebook with Oculus and many others are working to transform our Reality with new products and services in the not-too-distant future. Therefore Apple, Microsoft, Google and Facebook is approaching AR/VR from different perspectives and in this session we will try to understand how these different technologies work and which best suits the different areas (industry 4.0, tourism, healthcare, ...) .

- 29. Pros • Accuracy (you can add more trackers around the room to increase accuracy) • Latency very low (reduce VR sickness). Cons • Setup • Occlusion • Limitation of the cameras (field of view)
- 31. • . Pros • Simplicity / No Setup • Less hardware needed (no external camera) • No limit of space (potentially) Cons • Reduced accuracy and latency • Only the object in front to the user can be tracked • Powerful hardware

- 38. Visual Inertial Odometry (VIO)
- 39. Visual Inertial Odometry (VIO) 6dof in real time : • 3D of xyz motion (translation) • 3D of pitch/yaw/roll (rotation) Pose is tracked: • via the Camera system, by matching a point in the real world to a pixel on the camera sensor each frame. • by the Inertial system (accelerometer & gyroscope — Inertial Measurement Unit or IMU) The output of both of those systems are then combined via a Kalman Filter which determines which of the two systems is providing the best estimate of your “real” position.

Lighting Estimation Estimation of light available in a scene in order to apply the correct amount of lighting to virtual objects. Hardware and Rendering Optimizations Apple A9, A10, and A11 processors.
- 47. • . Motion tracking Estimates a phone’s relative location based on internal sensors and video footage Scene Understanding Uses the camera to detect flat surfaces Lighting Estimation Helps virtual props cast accurate shadows and otherwise fit in with their surroundings Anchoring objects
- 50. • . ARCore vs Tango Tango’s dedicated infrared depth- sensing camera to create detailed 3D meshes. ARCore has to estimate scale based on the camera feed, while Tango directly measures distance. Nikhil Chandhok (AR director of product): “ARCore is for all the apps that we think that users want”
