arcore

问题 In my app I'm trying to use ArCore as sort of a "camera assistant" in a custom camera view. To be clear - I want to display images for the user in his camera and have him capture images that don't contain the AR models. From what I understand, in order to capture an image with ArCore I'll have to use the Camera2 API which is enabled by configuring the session to use the "shared Camera". However, I can't seem to configure the camera to use any high-end resolutions (I'm using pixel 3 so I

问题 I am setting up a android app by Kotlin, and I want to get image score for arcore. On this page they say: Run arcoreimg eval-img to get a quality score between 0 and 100 for each image. And I just found a program for Linux, macOS, Windows to unzip the arcore-android-sdk-1.11.0 . I want to calculate arcore image score via my Android app. How can I calculate the image score if the arcore team doesn't support it? I found some posts that run the Windows program on Android, but It is 'How To Run

问题 I'm trying to place a large 3D object (generated from .obj file) in front of camera and not able to do it. The model gets placed considering the hit result as the center point. Any way to get it done? 回答1: The following code will place an anchor 1M in front of the camera - you can adjust the depth to whatever you need: // Place the anchor 1m in front of the camera. Log.d(TAG,"adding Andy in fornt of camera"); Frame frame = arFragment.getArSceneView().getArFrame(); Session session = arFragment

问题 I am trying to figure out how to modify HelloARController.cs from the example ARCore scene to place objects directly in front of the camera. My thinking is that we are raycasting from the camera to a Vector3 on an anchor or tracked plane, so can't we get the Vector3 of the start of that ray and place an object at or near that point? I have tried lots, and although I am somewhat a beginner, I have come up with this From my understanding, ScreenToWorldPoint should output a vector3 of the screen
