Distance Calculation

[Manikandan R]

Hi,

      I am using Camerax to capture my image, I want find the distance from camera to object. Trying to use ARFragment surface and arcore but couldn't find the distance. If implement ar core lib camera zoom and capture not working.

Code Snippet:

implementation "com.google.ar.sceneform.ux:sceneform-ux:1.15.0"
implementation 'com.google.ar:core:1.39.0'

arFragment = supportFragmentManager.findFragmentById(R.id.ar_fragment) as ArFragment

val imageAnalysis = ImageAnalysis.Builder()
    .setBackpressureStrategy(ImageAnalysis.STRATEGY_KEEP_ONLY_LATEST)
    .build()
imageAnalysis.setAnalyzer(cameraExecutor, ImageAnalysis.Analyzer { image ->   

            if (arFragment.arSceneView.session != null &&
                arFragment.arSceneView.arFrame?.camera?.trackingState == TrackingState.TRACKING
            ) {
                // Perform hit test using ARFrame and image coordinates
                val hitResultList = arFragment.arSceneView.arFrame!!.hitTest(
                    image.width / 2f,
                    image.height / 2f
                )

                if (hitResultList.isNotEmpty()) {
                    val hitResult = hitResultList[0]
                    val distance = hitResult.distance // Estimated distance in meters
                    Log.d("Distance", "Estimated distance: $distance meters")
                }
            }

            image.close()

})

Thanks & Regards,
