pyrealsense2 on Nanopi

Follow
Alexeyp

Good day to all. I tried to install pyrealsense2 on nanoPi to read freames from camera model L515

The OS installed is Description: Ubuntu 20.04.2 LTS

I tried to install pyrealsense2  with pip3  - got error,  so I build it from source 

Then I tried to start simple python script from examples

export_ply_example.py

 

And received following error

Traceback (most recent call last):
File "test.py", line 24, in <module>
pipe.start(config)
RuntimeError: No device connected

 

Camera is connected, I can read frames through openCV

dmesg shows me: 

[ 8313.494353] input: Intel(R) RealSense(TM) 515: Int as /devices/platform/usb@fe900000/fe900000.dwc3/xhci-hcd.1.auto/usb8/8-1/8-1:1.0/input/input2

What is wrong? How can I fix it?

    Hello Alexeyp,

    Thank you for contacting us.

    Can you please try to apply udev rules and then check it?
    https://github.com/IntelRealSense/librealsense/blob/master/doc/installation.md#prerequisites

    sudo cp config/99-realsense-libusb.rules /etc/udev/rules.d/
    sudo udevadm control --reload-rules && udevadm trigger

    Hello Alexeyp.

     

    My apologies for the late response.

     

    Try to configures the librealsense cmake build with: 

    cmake .. -DBUILD_PYTHON_BINDINGS=true -DFORCE_RSUSB_BACKEND=true

     

    Regards,

    Zulkifli

    Hello Alexeyp,

    Have you tried the camera on a different computer? Does it work?
