DLPLCR4500EVM: DLPLCR4500EVM

Hi David,

I will discuss with our team and get back to you very soon.

Thanks,

Navneet

Greetings,

after having switched to Windows 7 Enterprise, I still can't get the components to work. After successful step 2-4 the projection for focusing won't start and the projection of the checker board is not displayed. 

Did anybody has these issues jet? Is there a fix? 

While jusing my own SDK (made with changes) this Step does work but when calibrating the camera and projector the number of the projector remains 0 of 5, while the projector is adding up until 5 and then the program crashes.

Regards, 

David

Hi David,

Kindly wait for a few more days. We'll get back to you shortly. Thanks for your patience.

Thanks & Regards,

Hirak.

Hi Sanjeev,

I'm able to connect to the EVM with the GUI and even change the Starting Patterns and change the modes as you can see in my screenshot.

I used the DLPR350PROM_v4.0.bin file for Firmwareupload and even tried my own made .ini file with Stored Patterns. It all worked well. But while using the LCr4500_3D_Scanner_Application_v2 it still didn't processed the Step 4 (kamera calibration) because it did not turn on the projector unit of the 4500 evm. And same thing happend for the step 5 (system calibration). With my own SDK build i was able to turn on the projector but i could not get through the Step 5 cause it showed this picture: 

Is it possible to get a more stable pre build exe file for scanning? I'm running out of time. 

Regards, 

David

David,

The exe we released with TIDA-00254 is indeed the stable one. 

Since you mentioned you are able to perform all the steps using the GUI i think your hardware connection is okay. 

You also mentioned following comments -

=> In the SDK setup what is your camera configuration? can you share config_camera.txt file settings? Are you using PointGrey or OpenCV camera type? I recall you are using different camera...  what happens if you select OpenCV ( i recall with this you are getting only 640x480 resolution), have you fixed this issue?

You also mentioned steps 2 - 4 successful but you have have issues chessboard capture never goes beyond 0 of 5. Can you clarify?

Do you have any other simple USB webcam, you can perhaps try with OpenCV camera type settings.

Sorry unfortunately it is going to take more time as we need to ascertain if the problem is coming from camera or camera interface.

Hello Sanjeev,

This is m config_camera.txt :

CAMERA_PARAMETERS_FRAME_BUFFER_SIZE = 72

####################
##OpenCV Camera #
####################
#OPENCV_CAM_PARAMETERS_EXPOSURE = 0

####################
##PointGrey Camera #
####################
PG_FLYCAP_PARAMETERS_GAIN_DB = 18
# For below parameter set
# Rolling shutter color Camera - MONO8
# Global shutter Monochrome camera - RAW8
PG_FLYCAP_PARAMETERS_PIXEL_FORMAT = MONO8
PG_FLYCAP_PARAMETERS_SHUTTER_EXPOSURE_MS = 33
PG_FLYCAP_PARAMETERS_FRAME_RATE_HZ = 30
PG_FLYCAP_PARAMETERS_STROBE_SOURCE = 2
PG_FLYCAP_PARAMETERS_STROBE_ENABLE = 1
PG_FLYCAP_PARAMETERS_STROBE_POLARITY = 1
# For below parameter
# Rolling shutter color camera - 5.0
# Glocal shutter Monochrome camera - 0.0
PG_FLYCAP_PARAMETERS_STROBE_DELAY = 0.0
PG_FLYCAP_PARAMETERS_STROBE_DURATION = 1.0
PG_FLYCAP_PARAMETERS_AUTOEXPOSURE = 0
PG_FLYCAP_PARAMETERS_EXPOSURE = 1.0

But I use the OpenCV camera. I tried the Microsoft Livecam HD-5000 and the Logitech Brio.

Unfortunately I'm not able to get the right resolution in OpenCV with all my IDS cameras. So my approach is to use a webcam.

Basically the TIDA-00254 exe does not switch on the projector for calibrating the camera (step 4) and does not switch on the chessboard projection (step 5).
With my own exe this is possible. The configuration files are the same and with both I use the openCV settings.

My biggest question is. When will I order the new camera from Flir? Will the whole system work properly? the remaining time for my project is very limited, so I'm thinking about ordering the camera.

Ok I could finish the steps today by changing the config files. Thanks for the hint! In OpenCV the resolution with all different cameras is cut to 640x480 in the application. Is there an idea to change this resolution without creating a complete SDK? Mostly the drivers of the old camera are missing to create the SDK. Or could you perhaps provide me the original drivers for the Point Grey Camera?

Thanks for the help already and many greetings
David
