augmented-reality

问题 I am developing augmented reality android application based on real time location. It is a simple concept: my application should show some places around me. I have researched this intensively and yet I am still running into issues. I have my GPS coordinates and the target place's GPS coordinates. My question is: How can I retrieve what my phone's camera is looking at (for example a building)? What is the logical way to solve something like this? 回答1: Augmented Reality will transfer real

问题 Is it possible to use bespoke markers that do not resemble the "Hiro" marker like below. Could I potentially use a random shape (a solid red oval for example) as a marker? If this is not currently supported, could someone point me into the right direction to where I might start building this functionality? 回答1: AR.js supports custom markers. Make any silly image with the marker generator. Let ar.js know that you want to use your marker: <a-marker type="pattern" url="patterns/mypattern.patt">

问题 I'm working on AR Android app and when I get close to a renderable I want to make the colors of the AR video stream black-and-white, except the renderables of course. I searched the docs but it seams I cannot access the video stream to do it as shown in Exploring AR interaction (Google I/O '18). Does anyone know how to accomplish this? 回答1: To get a video stream from ARCore requires drawing the texture into a OpenGL 3.1 Context what is being captured. You can find here how to do it. After you

问题 I was thinking to do some modification to my existing AR app, and I wanted to split the view and add inside 2 ARSCNView in this way users can use the VR Card Box and have a different experience but Xcode is always returning me: Session (0x102617d10): did fail with error: Error Domain=com.apple.arkit.error Code=102 "Required sensor failed." So, I'm supposing that I can't run 2 ARSCNView sessions at the same time, or am I wrong? 回答1: The answer is: Yes, it's possible . Use the following code to

问题 i know what i am going to ask is already discussed sometimes but after going through all of them i can't found my complete answer so i am asking a new question when i tried integrating JPCT-ae with QCAR all goes well as expected, i got my modelview matrix from renderframe from jni and successfully transferred that in java to jpct model is shown perfectly as expected. but when i tried to pass this matrix to JPCT world camera my model disappear. my code:in onsurfacechanged: world = new World();

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 months ago . I've been looking into AR recently because I decided I should use it for my Android app and I found about Unity and Vuforia, which is probably the simplest way to implement AR. I've never before used Unity so I'm a complete beginner to it. I've followed this video: https://www.youtube.com/watch?v=YvSrZqP0elQ

问题 Guyz, I need to show the locations(ex restaurants, theaters, banks etc) on the camera preview when I move the camera around me. I know how to get the locations (ex from foursquare or Google maps) and I also know how to open the camera preview. I just don't know how to link these two. I googled it, but did not get a helpful post maybe because my english is not good. So guys I need your help, if you know any post regarding this issue please be kind enough to comment it. Thanks in advance. EDIT:

问题 I'm currently doing some experiments with RealityKit. I've been looking at some sample code, and I'm a bit confused about the differences between ARAnchor and AnchorEntity , and when to use one over the other. So far I know that: Both are anchors that describes a position in the real world. AnchorEntity can also have other Entity 's as children, so you can add model objects directly to the anchor. You can't do this with ARAnchor , you have to add model objects "manually" to the rootNode , and
