SDK support for object detection count and inference timing on ZED X One GS (mono) cameras

[pratibhamadaan]

Hi all. We are running the ZED ROS2 wrapper on a Jetson Orin Nano devkit
with a ZED 2i (stereo) and two ZED X One GS (mono) cameras. We’re using YOLOv11s for object detection.

For the ZED 2i stereo, the SDK’s built-in OD gives us per-frame
object counts (via ObjectsStamped) and processing time (via
/diagnostics).

We’d like to track the same two metrics on the ZED X One GS mono
cameras for benchmarking purposes.

Does the SDK provide any native path to expose inference timing
for object detection and get per-frame object
detection counts on mono camera streams?

Thanks!

The Object Detection module of the ZED SDK is only available for stereo cameras via the sl::Camera object. The sl::CameraOne object to control the ZED X One “monocular-like” does not provide it.

You can combine two ZED X One cameras in a virtual stereo camera to run Object Detection with them:
