Devices not recognized after windows reboot

2011-01-12T00:14:44+00:00

Actually iìm using 3 PScameras, ned to extend it to 5, anyway, I builded my own plugin for vvvv, and it works fine, but, when i restart windows, i hae an error in usb port, devices cannot being recognized, if i unplug and plug again cameras, sometimes it works.
I tries also precompiled sample for multicamera, using the DLL that enables more then 2 ps devices, same result, when i restart i cant use ps cameras…how can i solve this ? does anybody had the same issue, using more then 2 cameras ?

From depth RGB to depth RAW

2010-11-25T16:38:02+00:00

Hi,

regarding the CL NUI Platform - Kinect driver, is there anyone (I guess AlexP would be the one) who could explain me how the conversion from depth in RGB (the buffer return by GetNUICameraDepthFrameRGB32) to depth RAW ( the buffer returned by GetNUICameraDepthFrameRAW) is done?

Clearly, it must be some bit operation, as the rgb buffer is a PWORD while the raw one is a PUSHORT.

I would really like to know how the RGB bits are written into the raw buffer… I am trying to do some manipulation on the rgb depth and then reconstruct the raw buffer.

Thank you very much!

Processing.org Library Usage

2009-12-30T20:16:02+00:00

AlexP,
Sometime ago someone in the Processing community has written a Processing/Java library or wrapper for your driver to use the camera to Java. It is a great way to attract visual artists and multitouch folks. Now I can’t find links to the Dec 09 version of your driver before someone told me the CL-driver is the current version. Unfortunately the person that wrote the wrapper is too busy to follow your recent updates so his library only works with your PS3Eye Camera Setup v3.0.0.0901.exe or older.
So could you still provide a link to this file? Thank you!

Kinect: No Camera or Audio Detected, just Motor

2010-12-13T20:47:04+00:00

Hi all,
I got a problem, that started after I got a blue screen, on 32-bit xp box using the latest driver.
Now when I insert the kinect usb, only the NUI Motor is detected and not Audio nor Camera.
Everything is in-place, usb and power, and I tried both the new driver as well as the older one.
Do you think the blue screen I got, damaged the cams?
Any work-arounds?

Thanx,
Yanis

Features in this release:
- Support for Windows XP/Vista/Win7 both x86 and x64
- Support multiple Kinect cameras
- Device serial number retrieval
- RAW, RGB24 and RGB32 Color frame data
- RAW, Corrected8, Corrected12 and RGB32 Depth frame data
- Full 30fps camera data streaming
- Reading of built-in Accelerometer x, y, z data
- Camera motor control
- Camera LED control
- Fully signed driver
- To get you started we have included sample source code written in C# as well as C/C++ SDK lib and header files

We are currently working on the upcoming CL NUI Audio component, although there are some potential issues related to DMCA so we will keep you updated. Thanks again and please feel free to share any code and/or videos of your projects build on CL NUI Platform. Also to make the CL NUI SDK better, we appreciate any feedback you might have while getting started.

Update:
-Fixed crashing issues on some systems
-Improved image stability

Thanks in advance

640x480 color mode freeze

2010-02-08T05:37:58+00:00

hi Alex,
we have a problem using the latest SDK and drivers with PS3eye camera. even with the sample application provided the camera freezes quite often it sometimes returns back to normal or we have to plug out and plug in the camera. we are capturing 640x480 30fps in color mode (although it hangs/freezes in black-n-white mode too). i have tried it with 2-3 computers all have the same problem. mentioned below is the configuration of the latptop/PC i’m using.

Core 2 Duo 2.2Ghz
3GB RAM
250GB HDD
Windows XP SP3

Please let me know what could be wrong here.

Parameter not updated

2011-07-13T13:28:36+00:00

Hi,

I am modifying CLEyeMulticamTest.cpp to use three cameras and set the rotaion to
zero intitally.

I have this method in CLEyeCameraCapture

void SetCameraParameter_zero(int param)
    {
        if(!_cam)    return;
        CLEyeSetCameraParameter(_cam, (CLEyeCameraParameter)param,  CLEyeGetCameraParameter(_cam, (CLEyeCameraParameter)param)-CLEyeGetCameraParameter(_cam, (CLEyeCameraParameter)param));
    } 

If I do the following only camera one is set to rotation 0

//Make camera orient in the right way
    for(int j=0;j<3;j++)
    {
       cam[j]->SetCameraParameter_zero(CLEYE_ROTATION);
    printf("j=%dn",j);
    } 

but if I use the same method in the switch and one by one set each
camera to 0 by keyboard input it works.

Any clues?
thanks, joby

Eye Platform 1.2 driver fails to load from Java VM (causing Processing to fail)

2011-06-14T02:59:23+00:00

The latest CL Eye platform driver v1.2 doesn’t load properly from the Java VM.

In particular, the CLEyeMulticam.dll fails to load due to “missing dependencies” and generates an UnsatisifedLinkError. However, this only occurs when you ask the Java VM for extra memory. (This is very strange.)

That is,

java ... works okay
but,
java -Xmx500M ... produces the error

This causes Processing, which asks for extra heap memory, to fail, which is the topic of a previous thread:
http://codelaboratories.com/forums/viewthread/68/P45/#1351

Older versions of the driver (notably 1.0.1.0109) do not have this problem.

Here’s my environment:
Windows 7 Ent x64 (Also happens in Windows XP Pro 32-bit)
Java 1.6 (jdk1.6.0_26)

The easiest way to replicate this error is to add a main method to CLCamera.java

public static void main(String[] args) {
System.out.println(CLCamera.cameraCount());
}

This will run fine with no args to the VM, but crash with java -Xmx500M

I’ve attached an old version of the driver 1.0.1.0109 for people who are having this problem. However, the older platform versions have bugs.

Kinect Calibration, Raw Near IR Images

2011-06-07T04:48:40+00:00

Hi,

I’m trying to perform Calibration between the Depth and RGB cameras on the Kinect using the CLNUI API. I’d like to access the Raw Near IR image that the kinect sees (which is the reflection of all the points of IR light from the real world) and *can identify a chessboard image in*. I’d need to use these to be able to develop a correspondence between the RGB and depth cameras, which aren’t currently calibrated together.

The current feeds that I have manged to pull from the kinect are all processed depth maps that can’t identify the Raw pull from the Kinect, but are interpretations of how the IR light hits the depth sensor.

I know that the libfreenect API does provide this pull, but I need to use the CLNUI API for some consistency. Any suggestions would be helpful.

Cheers!
