Zed-ros-wrapper: Error code: Camera Not Detected

[hslyu]

Hi,

I'm using ZED camera on ubuntu 16.04 LTS, nvidia TX2 board.
Originally, roslaunch ZED_wrapper zed.launch does work, but recently it does not work with this error message:
Through lsusb command, I found that there's no ZED camera recognized in my computer.
What can I do to detect ZED Camera?

[WASCHMASCHINE]

If the normal samples don't run, you should just contact the support from the website directly. This is not software related.

[wujiang]

Sounds like it's hardware connection issue. If lsusb doesn't return the device, it means it's either not connected or the usb controller is not enabled. Can you post your dmesg -Tw output when you plug or unplug your ZED camera?

[ChrisPsa]

The pre 2.2 ZED SDK had this issue on Ubuntu 16.04 when the OS was started without a screen attached (apparently it had something to do with the Xserver?). Anyway, updating to latest ZED SDK should fix the problem.

I have got same error , when ZED was connected Ubuntu 16.04, it was working fine on Jetson TX1, but when connected to laptop, it throws following error "ZED camera not found".
The output of "dmesg -Tw" is

@ncnynl sometimes I experience the same issue. ZED drops connection sporadically.

[ncnynl]

@wujiang , i have fixed this issue . i downgrade the firmware , it work fine.

[Myzhar]

@ncnynl @wjzhou Can you please add information about what combination of FW, SDK, device and Operating System cause this kind of issue?

[ncnynl]

@Myzhar

ZED newest FW is v1523
lsusb information is: uvcvideo: Found UVC 1.10 device ZED (2b03:f582)

ZED last old FW is v1142
lsusb information is: Found UVC 1.00 device ZED (2b03:f580)

On TX2 with FW v1523
run roslaunch ZED_wrapper zed.launch can not detect ZED Camera

So need downgrade FW from v1523 to v1142

How to downgrade
install Newest ZED SDK ， open ZED Explorer ， choose firmware v1142
SEE：https://github.com/stereolabs/zed-examples/issues/63

[Myzhar]

Thank you @ncnynl we are going to investigate

[Myzhar]

You can find the correct configuration for FW version and SDK version following this link:

Porblem was solved for me after message "CAMERA DETECTION ISSUE" by flipping the usb -C connector 180degree and plugging it in again.

[VGrondin]

I had this error when launching ZEDfu in live mode :
ZED >> ERROR: sl::Camera::Open has not been called, no Camera instance running.
Solved it by using another USB 3.0 connector. The one in front wasn't working but when i plugged it at the back of the tower it worked !

[zoombinis]

I am also getting this issue where Zed only seems to work on Ubuntu 18.04 (docker container) if an X11 Client is connecting to the X11 Server on my host machine.

I run Zed Explorer but no updates to firmware appear available. I currently have version 1523

I've tried plugging usb in and out but this really seems to be an issue somehow related to X11. For instance, I get this error (ZED connection -> CAMERA NOT DETECTED and the blue light of the zed does not turn on) only when running demos that have no visual gui like:

https://www.stereolabs.com/docs/ros/zed-nodelets/#examples

lsusb from inside the Ubuntu 18 container (with or without X11 connection to my host) reads:
Bus 002 Device 004: ID 2b03:f582

uname -r
5.4.0-52-generic

Cuda 10.2, Zed SDK 3.3. I've tried downgrading firmware too and that didn't fix anything

[Myzhar]

@zoombinis the ZED camera requires CUDA.
CUDA must be correctly configured to run in a docker container, otherwise the ZED SDK cannot work.
The version of the FW is not your issue.
Please read more about how to properly use Docker with ZED: https://www.stereolabs.com/docs/installation/docker/

[zoombinis]

@Myzhar not cuda, but you're right that I was missing --privileged mode and I thought that was only necessary for trying to run X11, but no it's necessary for any container running zed sdk.

Thanks!

[Myzhar]

I'm glad that you solved your problem.
--privileged is indeed required to correctly use CUDA with the ZED SDK inside a container.
