ArCore:如何将PlaneFindingMode限制为仅垂直表面? [英] ArCore: How to restrict PlaneFindingMode to only vertical surfaces?

问题描述

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通过PlaneFindingMode.VERTICAL标记使之成为可能，但是我不确定如何使用它.

I am new to ARCORE and Kotlin and trying a simple android-kotlin app that need to detect walls. I know Google's made it possible with PlaneFindingMode.VERTICAL tag, but I am not sure how to use it.

任何帮助将不胜感激.

Possible duplicate here but I'll answer it anyway.

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

This implementation is probably applicable to ARCore as well. But I tested this with SceneForm SDK

首先设置AR会话，然后使用扩展功能来修改平面查找.

Setup the AR Session first and use an extension function to modify plane finding.

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)
}
