OAK-D-SR-POE ToF DepthAI Viewer/ Connection

LLiwa

When running the DepthAI Viewer the application allows me to select the device from the drop-down. It then allows me to configure the viewer and press apply. However, the stream never shows up. Instead, I get a RuntimeError: Communication exception - possible device error/misconfiguration. Original message 'Couldn't read data from stream: 'input' (X_LINK_ERROR). I bought the recommended POE switcher and updated the bootloader to the latest version. Part of the crash dump json I got is attached.
{
"crashReports": [
{
"crashedThreadId": 184614924,
"errorSource": "RTEMS_FATAL_SOURCE_EXCEPTION",

},
"errorId": 0,
"trapContext": {
"trapAddress": 2205292660,
"trapName": "Bad trap",
"trapNumber": 9
}
},

For more context, I am able to get the RGB demo running as well as the mono camera example. However, sometimes the device will disconnect and the "no device available" message will appear. To connect again I have to power cycle the camera. Reseatting the ethernet cable doesn't restart the connection.

What settings are you trying to apply to the device pipeline? I find that when there isn't enough bandwidth the device simply crashes.

I have tried a bunch of different setups. I read about the bandwidth issue so I tried to stream just one camera, like Cam_A at 5 fps and the lowest resolution. It still gives the 'Couldn't read data from stream: 'input' (X_LINK_ERROR)

Hi LLiwa
Ok, weird.
Can you run these scripts to check?

Thanks,

Here are my results for the scripts:

My RGB image looks off. The screen flickers and goes between a black and white image and a blue/yellow scale image? I have attached a picture of what I get.

Yes, that is fine. The socket used is CAM_A which if TOF and isn't meant to work that way. If you used CAM_B or CAM_C, the stream would look fine.

So the device is functioning correctly. So it's just depthai viewer that is not working? Can you try reinstalling it with the latest version 0.2.8, if it still fails to work, add the whole crash dump please.

Thanks,

Ok, that makes sense regarding the video stream.

I don't need the viewer to work for my application so I'd rather focus on the other issues that I am having, namely in the calibration. That being said I did update the depth viewer and retry and I got this crash dump in case the issues are related:

Regarding calibration, I am running into problems with both the stereo calibration and the ToF calibration. For stereo, when running the script I get this error:
File "C:\XXXXXXX\depthai\calibrate.py", line 1181, in <module> Main().run()
File "C:\XXXXXXX\depthai\calibrate.py", line 1170, in run self.startPipeline()
File "C:\XXXXXXXX\depthai\calibrate.py", line 465, in startPipeline pipeline = self.create_pipeline()

File "C:\XXXXXXX\depthai\calibrate.py", line 556, in create_pipeline cam_node.setResolution(camToRgbRes[cam_info['sensorName'].upper()])

KeyError: 'OV9282'

Checking the dictionary keys I get:
camToMonoRes = {

            'OV7251' : dai.MonoCameraProperties.SensorResolution.THE_480_P,

            'OV9282' : dai.MonoCameraProperties.SensorResolution.THE_800_P,

            }

camToRgbRes = {

            'IMX378' : dai.ColorCameraProperties.SensorResolution.THE_4_K,

            'IMX214' : dai.ColorCameraProperties.SensorResolution.THE_4_K,

            'OV9782' : dai.ColorCameraProperties.SensorResolution.THE_800_P,

            'IMX582' : dai.ColorCameraProperties.SensorResolution.THE_12_MP,

            'AR0234' : dai.ColorCameraProperties.SensorResolution.THE_1200_P,

            }

It looks to me like the OV9282 sensor isn't defined in the RGB resolution causing the error? not sure?
