With a 3D pass-through camera, you can catch a ball thrown at you. If you have a live 3D model of your environment, you can use time-warp reprojection to hide both camera and headset latency, and you can fix parallax by rendering the 3D model from the real position of the user's eyes. One reason people are excited about depth mapping is that pass-through with a depth camera can fix both issues. There is a way of using two mirrors to virtually place the cameras in the user's actual eye positions, but that's difficult and bulky. This means the world will appear to shift around as you move, and you will miss things when you reach for them. Parallax is because the cameras are usually not at the same position as your eyes, but offset by the thickness of the headset, if the IPD is even the same. The time from an image being exposed on the camera's sensor to that image showing up on your headset's screen is somewhere around 50ms (for a 30 Hz camera (one frame delay) and a 90 Hz headset (two frames delay)). The two main issues with pass-through AR are latency and parallax. The attached laptop factor also will allow for some processor-intensive functions like colour correction. Currently it seems that the best way to achieve a fully mobile HUD type situation is with a VR headset and camera pass through. In terms of alternatives for this type of project, I am aware of items like the ODG R9 glasses (not available for 6 months, and also only 50 degrees FOV). My plan was to buy a couple of high quality webcams and create my own version of this, but if something like this already exists there is no point dedicating time to that (also all of the old tutorials on webcam pass through into the rift are from the DK2 and the new runtime drivers are quite different now - requiring the store to be open, requiring a sensor plugged in, etc). Things like, distance to a waypoint, floating markers over GPS co-ordinates, rotating compass, etc. My plan is to augment the HUD with contextual information that does not require depth mapping (at this stage). but what I am interested in is pure AR HUDs.ĭoes anyone have any experience with this device, or any alternatives? I would plan on not using the real-time mapping feature (to save on processing) and to get the best possible (in terms of low latency and high quality) video stream to the eyes. It is being marketed for it's depth mapping capabilities. The zed mini is a device that can attach to the outside of a Rift, Vive, or (as it seems) a mobile VR headset. No low effort memes, gifs, image macros, etc.Read the FAQ before posting a question.This is a place for friendly VR discussion, don’t start drama, attack, or bait other redditors.Then in the folder of the project, create a file named CMakeLists.Welcome to /r/Oculus, a place for Oculus fans to discuss VR. In this folder, add the file main.cpp given above. Folders and filesĬreate a folder where you want to put your project. The compilation method works on every platform supported by the ZED SDK and provides an easy way to generate a project for every major IDE.ĬMake 3.5.0 is the recommended minimum version. Let’s see how to compile this! Cross-platform method using CMake Printf("Hello! This is my serial number: %d\n", zed_serial) Code Overview Open the camera As in previous tutorials, we create, configure and open the ZED. Download the Positional Tracking sample code in C++, Python or C. Tarantino was unsure whether to play Jimmie or Lance, choosing Jimmie as he wanted to be behind the camera during Mias overdose scene. Int zed_serial = zed.getCameraInformation().serial_number First, download the latest version of the ZED SDK. Get camera information (ZED serial number) Init_params.sdk_verbose = false // Disable verbose mode Here is a very simple “Hello World” program, that just initializes the ZED camera and prints its serial number: Then start coding your first program using the ZED camera. Note: On Windows, please use Visual Studio 2015. Prerequisitesįirst of all, make sure that your environment is set up correctly, as explained here. The goal of this tutorial is to show you how to build applications using the ZED SDK.Īll our programs are developed in C++, therefore working knowledge of C++ programming and the C++ compilation pipeline is required (command line or IDE) for this tutorial.
