Zed-ros-wrapper issue with object detection


I’m using the zed-ros-wrapper with SDK 3.8.2 on jetson nano and I have an unexpected behavior. After some times (it can be 3 hours), the object detection module stops working.

To be more accurate, the following code :

    sl::ERROR_CODE objDetRes = mZed.retrieveObjects(objects, objectTracker_parameters_rt);

    if (objDetRes != sl::ERROR_CODE::SUCCESS) {
        NODELET_WARN_STREAM("Object Detection error: " << sl::toString(objDetRes));

    if (!objects.is_new) {

Doesn’t produce any warning (meaning the retrieveObject is a success BUT there is no new objects (so the code go through the if statement)

In parallel, I see that the grabbing process continues to work successfully. Any idea ?



Hi @avanmalleghem
the problem has been solved with the v4 of the ZED SDK
