Hi @tom,

Thank you for your reply. The problem was with the parameters for PX4, even though we downloaded the parameters from the ModalAI website it did not work. We eventually solved it by unbricking the RB5 and reinstalling everything.

I am trying to connect the VOXL2 to QGC, voxl-px4 is running but the only data I received was the heartbeat. I used to be able to connect it without any issues but now there seem to be a problem. Even though, voxl-px4 is running it seems like that it does not send any information not even heartbeat. I tried to reinstall VOXL SDK but the process ends saying this:

These are the services running:

Has someone ever encountered a similar problem?

@tom thank you for your help.

I can only see these pipes in that directory. I managed to retrieve data from voxl-tflite-server0, however that is for the tflite-server and I cannot find the pipe for the hires camera without the tflite overlay.
Could it be that I forgot to start a service?

@Moderator thank you for your help. When I run cmake it throws an error saying that it cannot locate OpenCV, I am using

Find the OpenCV package

find_package(OpenCV REQUIRED)
include_directories( ${OpenCV_INCLUDE_DIRS} )

This is from the OpenCV documentation but it does not work for me. What could be the solution?

I wrote a script that opens and reads a pipe, however, I cannot seem to find the image pipes for the cameras. I am new to FIFO pipes, can someone help me where I can find the image pipe for the hires camera on VOXL2?

@Eric-Katzfey Thank you for your reply.

So if I want to have OpenCV and Numpy installed on the drone I have to download it directly onto the drone without using Docker?

Hi,
I am trying to run the voxl-cross image on the Voxl2 but after I push the image to the drone and try to run it I get this message.

I only added a few lines to the Dockerfile (to have opencv and numpy) and changed the build command to be compatible with the target environment (linux/arm64/v8) as I had that error originally.

Does someone know what the problem could be? I cannot find any information about this on the internet.

I had the same issues but even with different lighting, I cannot get it to work. I managed to calibrate the tracking camera but not the stereo. Does anyone have any idea how I could try to fix this?

I have the same problem: The reprojection error is to large for the stereo cameras and the calibration fails.

Hi,

I am trying to stream the cameras from a Sentinel Drone to either VLC or QGroundControl, however, there seems to be a connection problem. I have the following services running and when I open QGC it says waiting for video. I changed the video settings in QGC as advised online and tried UDP and RTSP, but none of them worked. I tried RTSP with VLC and it did not work either.
Could someone tell me if I missed a step or what could be the problem?

I am trying to set up the Sentinel Drone for the first time, but when I plug in the drone into my laptop and I'm trying to run adb shell it cannot find the device. When I go to the Device Manager on my Windows it says that the driver is missing for this device. Do you have any idea about how I could fix this?
