Proposal

New 3.7 SDK gives the option to enable objects re-identification by setting BatchParameters::enable and provides control over:
id_retention_time, and latency.

Even though enable tracking is referenced in zed_camera_components.cpp,

zed-ros2-wrapper/zed_components/src/zed_camera/src/zed_camera_component.cpp

Line 1130 in 55a4302

getParam("object_detection.object_tracking_enabled", mObjDetTracking,

sl::ObjectDetectionParameters od_p;
od_p.enable_mask_output = false;
od_p.enable_tracking = mObjDetTracking;
od_p.image_sync = true;
od_p.detection_model = mObjDetModel;
od_p.filtering_mode = mObjFilterMode;
od_p.enable_body_fitting = mObjDetBodyFitting;
od_p.body_format = mObjDetBodyFmt;

it is not provided in the launch file:

zed-ros2-wrapper/zed_wrapper/config/zed2i.yaml

Use-Case

object tracking with re-identification

Anything else?

No response

[Myzhar]

The re-identification is not yet available in the ROS2 wrapper.
It will be added soon.

Thanks!

Curious if support for this has been added for this in the ROS2 wrapper yet?
