Kinect in labView

[Jeroen_O]

Hi

I am having trouble connecting the Microsoft Kinect V2 in labVIEW.

I am working in windows 10 and I'm using labVIEW 2015.

I have downloaded the required drivers and my Kinect works on my computer with the SDK V2.0.

But when I open labVIEW, try to find drivers and add-ons, connect to instruments, I see the Kinect instrument drivers, but my instrument folder is empty.

When I try and scan for instruments, no instruments are found.

I tried to perform a specific search for the instrument but there is no right manufacturer name in the list.

What should I do now?

You need to download and install another set of drivers, specifically for LabVIEW. There are two sets that are available:

- Haro3D library: https://decibel.ni.com/content/docs/DOC-40832

or

- MakerHub library:  http://sine.ni.com/nips/cds/view/p/lang/en/nid/213126

It worked! I used the first link and it Kinected into labVIEW!

Thank you so much!

Thank you for the help! Everything is working perfect!

I just have one question.

When a person enters in the screen of the Kinect, I get assigned a what apears to be random person number.

I was wondering, what effects this number?

I don't think the number will actually be random.

Is the the position where the person is standing? Or how is this chosen?

Is there any place where I can find an answer for this question?

The Kinect assigns an ID number to each body. The exact logic how the ID number is assigned escapes me, if there is any (maybe just the order of appearance of the bodies).

The ID number will change if a person steps in and out of the Kinect view. Also, the ID numbers migth get swaped if 2 bodies pass in front of each other.

In any case, you can get more information about ID numbers (and about the Kinect in general) from those links:

Thank you so much! again!

Hello again Marc!

Thanks to your advice i've come extremely far and made so much program.

Im actually to the point where im almost done, but i just have a little problem.

When i run my labview program my used memory keeps going up, until the moment where it crashes with the error: out of memory.

I went back to the basic program with the examples and found out that it does the same thing with the examples.

But because my program got so big and i use so much data, it crashes way faster.

Anyways, i was wondering if you had a fix for my problem, if i maybe could clean the array up so i wont stack data but just replace it instead.

Thanks

Hi,

I don't know which library you are using: the MakerHub one or Haro3D? If you use Haro3D, there was a small memory leak in the body API in version 1.0.0. The leak was small and nobody ever reported a problem but it was fixed in version 1.2.0 (documented in version History of manuals version > 1.2.0). I suppose that at some point the memory leak would create actual problem. The solution would be to upgrade to version 1.2.0.

If you are using the MakerHub library, you can ask directly on the MakerHub forum.

Thanks for the quick reply!

I am using Haro3D

I'll look into updating it, thanks a lot!
