Error with Matlabfunctions within the new Version 2015b (pcfromkinect, depthtopointcloud)

Hi,

i have been working with the Windows Kinect V1 and Matlab 2015a.

I used the function "depthtopointcloud" (and tried the new function "pcfromkinect") and it worked fine on 2015a but with the new version i get the same error for both functions available:

No public property InputDepthMap exists for class videosource.

Error in imaq.internal.KinectColor2DepthMap

Error in vision.internal.visionKinectColorToSkeleton

Error in pcfromkinect (line 96)
        vision.internal.visionKinectColorToSkeleton(depthDevice, depthImage, colorImage, isDepthCentric);

Error in kinect_image (line 22)
    ptCloud = pcfromkinect(depthDevice,depthImage,colorImage);

It seems that its a common problem at the moment (f.e. here ).

So my question pretty much is: Is there a fix for this coming soon? Or is there any way to solve the problem of creating a pointcloud with the new version of matlab?

Thanks in advance

Hi Tobias,

The issue mentioned above seems to have occurred often when using an XBOX sensor, which is not supported by the Image Acquisition Toolbox. Could you confirm the device being used and share a sample code? Are you also working with the Computer Vision Toolbox for this function?

Hi,

yes i am using the XBOX Sensor. It worked perfectly fine with the previous version(s) of matlab. Did they change their policy regarding the XBOX Kinect Sensor?

I tried my own code as well as the sample code from the matlab-help for example this one: depthtopointcloud.

The error is the same as in the first post mentioned.

I implemented the functions through normal matlab scripts so no particular use of the toolbox i guess.

This function and the Image Acquistion toolbox only work with the Kinect for Windows sensor, and not with the XBOX 360.

See supported hardware here .

Is there any solution found for this problem.?

Please help !

Thanks..

No, the Kinect XBOX 360 depth sensors are not going to be supported.

The Kinect XBOX 360 depth sensors use an undocumented interface that is different than the Kinect for Windows sensors, and Microsoft decided to lock the interface down, made it inaccessible, and will not release the specifications. This was considered rather odd because the policy for Kinect for Windows was very open.

Anyhow, it is not just a matter of "Mathworks has not gotten around to it", it is a matter of "Microsoft does not want people to be able to do this."
