Starling 2: TOF sensor not recognized by VOXL Portal

[Hector Gutierrez]

@Alex-Kushleyev

Hi Alex - apologies for the long delay. Here is the output I get from voxl-camera-server -l :

voxl2:/$ voxl-camera-server -l
DEBUG: Attempting to open the hal module
DEBUG: SUCCESS: Camera module opened on attempt 0
DEBUG: ----------- Number of cameras: 0
DEBUG: Note: This list comes from the HAL module and may not be indicative
DEBUG: of configurations that have full pipelines
DEBUG: Number of cameras: 0

In other words, my drone does not see any cameras at all. The same shows when running VOXL portal (zero cameras).
I just run apt update && apt upgrade successfully in this drone.

The other command you mentioned gives the following output:
voxl2:/$ ls /usr/lib/camera/sensormodule
/usr/lib/camera/com.qti.sensormodule.imx412_2.bin /usr/lib/camera/com.qti.sensormodule.imx412_3.bin

Please advise - something is really wrong here since I cant see any of my cameras. My Starling 2 has the camera configuration C27 (triple tracking)
Thanks, Hector

[Alex Kushleyev]

@Hector-Gutierrez , since you have a standard camera configuration, you should run the following command to configure your VOXL2 for C27:

voxl-configure-cameras 27

This command should copy the correct sensormodule files to /usr/lib/camera and set up a default config in /etc/modalai/voxl-camera-server.conf for this camera arrangement.

Thanks. The output of voxl-camera-server -l is shown below, but it seems generic. Several issues remain:

• voxl-camera-server detected 4 cameras, but my drone has 5

• when opening voxl portal, zero cameras are detected. Also, the IMU plotter runs but gives empty plots.

Please let me know what to try next - it does seem like a hardware problem.

Thanks - Regards, Hector

[Alex Kushleyev]

@Hector-Gutierrez ,

When you were looking for cameras in voxl-portal - was the voxl-camera-server actually running? you need to make sure that it's running (either as a background service, which normally starts up using systemd right after boot, or manually if you are running the camera server in a terminal in the foreground).

It does look like the 3 AR0144 and 1 IMX412 were detected, so lets first make sure you can view those corresponding streams first.

Alex

[Hector Gutierrez]

@Alex-Kushleyev

Yes, voxl-camera-server was running. In fact I stopped it and started it again to be sure it was running.
I also checked with voxl-inspect-services and it showed the camera server was running. And yet I cannot open any of the cameras on voxl Portal - the portal starts properly but there are no cameras. And also the IMU plots look empty.
And the ToF sensor is not being detected ...
Please let me know what to try next.

Thanks, Hector

[Alex Kushleyev]

@Hector-Gutierrez , with the voxl-camera-server running on the foreground, please run the following and monitor the output of voxl-camera-server as well:

voxl-inspect-cam -a

This test should connect to ALL the camera streams generated by the voxl-camera-server and print out the stats.

Still dont see the ToF sensor ... Please advise
Thanks, Hector

[Alex Kushleyev]

@Hector-Gutierrez ,
OK, so it looks like that the 4 detected cameras are actually streaming data.

I am not sure why voxl-portal is not showing any cameras. When you access the voxl-portal via browser, do you see the actual portal (with green menu bar at the top), but no cameras are listed in the Cameras section?

How are you connected to the drone? (wifi, adb, etc).

Regarding the TOF sensor, since voxl-camera-server -l did not show that the TOF sensor is detected, the stream is not available.

Please double check that com.qti.sensormodule.irs2975c* file is in /usr/lib/camera/ directory - please provide the exact name or let me know if it's missing.

Also, can you please take a picture of your cameras plugged into the M0173 camera front end? I just want to make sure the TOF sensor is plugged in correctly.

Alex

@Alex-Kushleyev
Hi Alex, I disassembled and reassembled the camera board and now I get 4 cameras in VOXL Portal ! I did reconnect the ToF sensor as well to the camera board, it seems properly connected.
The cameras working well are hires_large_color, and all three tracking cameras. I still dont see the ToF sensor , and the view of the hires camera is blurry (out of focus). The hires camera was recently replaced, so how to get it into focus is another question.
I listed the files on /usr/lib/camera and found this file: com.qti.sensormodule.irs2975c_3.bin
So now we are down to the ToF sensor (and to put the hires camera in focus). Let me know what to try next !
thanks, Hector

@Hector-Gutierrez , in order to focus the hires camera (I am assuming IMX412), you can twist the lens in the M12 lens holder. Normally we do focus the hires cameras to a norminal focus distance, but maybe you had one from earlier batch which was not focused. Also, focus of the camera depends on the application, so it is recommended for users to double check and correct the focus for their needs. If there is some sealant on the threads, it is not permanent and can be removed using tweezers - loosening it up a bit should allow you to twist the lens inside the holder.

Regarding the PMD TOF, not sure yet. Has it worked before?

Hi Alex - As you suggested, the focus issue was resolved by twisting the lens until good focus at 3 m. was achieved.
The TOF sensor remains a problem. I've tried detaching and reconnecting its cable (on both ends) but no luck so far.
Both VOXL Portal and voxl-camera-server -l only see 4 cameras.
We didnt use the TOF sensor before so I didnt notice if it was working previously or not.
Please let me know what to try next - thanks, Hector

@Hector-Gutierrez , can you please send a picture of the TOF sensor connected to M0173? Just to make sure the connections are correct.

@Alex-Kushleyev
Hi Alex - attached are some pictures of the connection. Something odd is happening. The connector engages its socket in two different locations relative to the hole for the screw. In the centered location (where it should be!) the TOF sensor causes a power short and the drone wont boot (see picture with red LED). In the off-center location there is no short and the drone boots, but I only get 4 cameras and the TOF is not visible.

Update from my previous post. I install the TOF connector in the centered location and fully attach the screws (including the one that secures the TOF ribbon cable). There is no short, the drone start normally, and I get 4 cameras on VOXL portal, but no TOF. Also voxl-camera-server -l only see 4 cameras. So TOF connection is definitely Ok, but sensor not present.

@Hector-Gutierrez , I am sorry, i was not able to access the image you shared. Can you please just resize / crop the image so that it fits into the forum? Just please make sure the details are still easy to see.

Thank you!

Hi Alex - attached are the pictures.

After installing the TOF connector in the centered location and fully attach all the screws (including the one that secures the TOF ribbon cable), there is no short and the drone starts normally. I get 4 cameras on VOXL portal, but no TOF. Also voxl-camera-server -l only see 4 cameras. So TOF connection seems definitely Ok, but sensor not present. Seems to me like a bad TOF sensor - let me know your thoughts.

@Hector-Gutierrez Clarification on the pictures. The top picture is the centered position of the TOF ribbon cable. The bottom picture can be disregarded. The connection is done on the centered position (top picture). Thanks.
