Unity Crash at 3D Scan Progress

Hi everyone,

I have a question as I use unity to do 3D scan.Unity Editor would crash with no error.

The version of Unity is Unity 5.2.3f1
The OS version is windows 10.

The version of RS SDK is 2016 R1.

Can anyone help me to solve this problem?

The source code to do the 3d scan. is in the below.

using UnityEngine;
using System.Collections;

public class ScanModule : MonoBehaviour{

	static PXCMCapture.Device device;
	private PXCMSenseManager psm;
	private pxcmStatus sts; //Check error status
	private PXCM3DScan.Configuration scan_config = new PXCM3DScan.Configuration ();
	private PXCM3DScan scan;

	/*3D Scan Preview Image*/
	private Texture2D  scanTexture2D;
	public GameObject  scanPlane;

	private bool scan_complete = false;

	public void Init(){
		/* Create an instance of the PXCSenseManager interface */
		psm = PXCMSenseManager.CreateInstance();
		if (psm == null){
			Debug.LogError("PXCMSenseManager Initialization Failed");
			return;
		}

		/* Set Color & Depth Resolution */
		psm.EnableStream(PXCMCapture.StreamType.STREAM_TYPE_COLOR, 1920, 1080, 30);
		psm.EnableStream(PXCMCapture.StreamType.STREAM_TYPE_DEPTH, 640, 480, 30);

		/* Enable the 3D Scan video module */
		pxcmStatus result = psm.Enable3DScan();
		if (result != pxcmStatus.PXCM_STATUS_NO_ERROR)
		{
			Debug.LogError("Enable 3d Scan Error : " + result);
			psm.Close();
			psm.Dispose();
			return;
		}

		/* Initialize the camera system */
		sts = psm.Init();
		device = psm.captureManager.device;
		if (result >= pxcmStatus.PXCM_STATUS_NO_ERROR && device != null) {


				device.SetColorAutoExposure(true);
				device.SetColorAutoWhiteBalance(true);
								
				/* Try to initialize the scanning system */
				scan = psm.Query3DScan();
				if ( scan == null ) Debug.LogError("3DScan module not found.");
				else{
					//result = scan.SetConfiguration(scan_config);
					if (result < pxcmStatus.PXCM_STATUS_NO_ERROR)
					{
						Debug.LogError ("PXCMSenseManager.Init Pass:" + result);
						scan.Dispose();
						return;
					}
				}

				/* Setup the scanning configuration */
				scan_config.startScan = true;
				scan_config.mode = PXCM3DScan.ScanningMode.VARIABLE;
				scan_config.options = (PXCM3DScan.ReconstructionOption.NONE);

				{
					Debug.LogError ("PXCMSenseManager.Init Pass:" + result);
					scan.Dispose();
					return;
				}
		} else {

	}

	void setConfigure(){

		scan_config.options = scan_config.options | (PXCM3DScan.ReconstructionOption.TEXTURE);

		pxcmStatus result = scan.SetConfiguration(scan_config);
		if (result < pxcmStatus.PXCM_STATUS_NO_ERROR)
		{
			Debug.LogError ("PXCMSenseManager.Init Pass:" + result);
			scan.Dispose();
			return;
		}
	}

	void ScanUpdate(){
		/* Get preview image from the 3D Scan video module */
		PXCMImage preview_image = scan.AcquirePreviewImage();

				preview_image.AcquireAccess (PXCMImage.Access.ACCESS_READ, PXCMImage.PixelFormat.PIXEL_FORMAT_RGB32, out scanImageData);               
				scanImageData.ToTexture2D (0, scanTexture2D);               
				preview_image.ReleaseAccess (scanImageData);  
				
				/* Apply the texture to the GameObject to display on */                 
				scanTexture2D.Apply ();

			}
			else

- Adapt your resolution, something like  COLOR: 960,540 60fps & DEPTH 640,480 60fps.

- senseManager is calling releaseFrame, but never acquireFrame?
