Question

我是ARCORE和Kotlin的新手，正在尝试一个需要检测墙壁的简单android-kotlin应用程序。我知道Google使用PlaneFindingMode.VERTICAL标记使之成为可能，但是我不确定如何使用它。

任何帮助将不胜感激。

Answer 1

可能的重复here，但我还是会回答。

此实现也可能适用于ARCore。但是我用SceneForm SDK进行了测试

首先设置AR会话，然后使用扩展功能修改平面查找。

override fun onResume() {
    super.onResume()

    //Check if ARSession is null. If it is, instantiate it
    if(arSession == null) {
        arSession = Session(this@EdgeActivity)
        arSession?.setupPlaneFinding()
    }
}


// Setup plane detection
private fun Session.setupPlaneFinding() {

    //Create the config
    arConfig = Config(this)

    //Pause the session | Not sure if this is required for modifying plane detection. I was using this for something else, try & modify at your end
    pause()

    // Modify the plane finding mode
    arConfig?.planeFindingMode = Config.PlaneFindingMode.VERTICAL

    //Reinstate the session
    resume()

    //Sceneform requires that the ARCore session is configured to the UpdateMode LATEST_CAMERA_IMAGE. | I kept getting an exception if I remove this line. Again, this method is part of a bigger code, this particular line may not be required at your end. Try & Modify
    arConfig?.updateMode = Config.UpdateMode.LATEST_CAMERA_IMAGE

    //Reconfigure the session
    configure(arConfig)

    //Setup the session with ARSceneView | Very important
    fragment.arSceneView.setupSession(this)
}

ArCore：如何将PlaneFindingMode限制为仅垂直表面？
