ARCore：如何将PlaneFindingMode限制为只允许垂直曲面？

Question

我对ARCORE和Kotlin是个新手，正在尝试一个简单的android-kotlin应用程序，它需要检测墙壁。我知道谷歌用PlaneFindingMode.Vertical标签使之成为可能，但我不知道如何使用它。

如有任何帮助，我们将不胜感激。

这里可能有副本，但我还是会回答的。

这种实现可能也适用于ARCore。但我用SceneForm SDK测试了这一点

首先设置AR会话，然后使用扩展函数修改平面查找。

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)
}
