Part II : Build the Gateway and get your position ! (old)

  You have proudly assembled at least two wireless cameras and you finally want to test them. Good ! Because at the end of this post, your cameras will be talking with the Gateway, and we will get 3D coordinates from the two sets of 2D coordinates. The big step will be building the gateway, which is a Raspberry Pi 2, and installing all the software. Let’s have a look at the steps we are going to go through : 1. Prepare your Raspberry Pi 2. Make it talk with the cameras 3. Behind the curtains : calculating the 3D position by image resectionning 4. Send data back to the user with Websockets As you can see, we still have a lot on our plates. But once you have understood the concept, it gets easier. Prepare your Raspberry Pi We are going to use a Raspberry Pi 2 as a Gateway to receive 2D positions from the cameras, compute them into 3D positions with OpenCV and send them back to the user via WebSockets. Get a Raspberry Pi 2 and all the stuff necessary to go with (5V supply, Wifi dongle, SD card) and a Nrf24L01+ with long range antenna. Install Raspbian on your […]

VR Tracker: DIY position tracking system – Introduction

Oculus Rift, VR One, Samsung Gear, Sony Playstation VR… All those Virtual Reality are great, but they are missing something ! They do not have a position tracking system ! This means you can look up down right left, but can’t stand up and move around in your room. Too bad because the best experiences happens when you can actually move around by yourself in your virtual environment. How do I know ? Well I have been working with many of those headsets as a consultant for an augmented reality company, and I have developed a 3D position tracking system compatible with all those devices ! And let me tell you, I have tested this tracking system with Samsung Gears, and the result was AWESOME !!! I was able to move around in a 5 meters by 8 meters room and therefore in my virtual environment. What is so great about position tracking ? The range of applications is much wider ! You can for example create an experience in a museum where users could visit a pyramid using VR headsets in an Egyptian exposition. Or visit an appartement or a building even before it has been built ! You could also create […]
