Description

I found an nconsistency between distance values and units in zed-sdk/object detection/birds eye viewer/python/cv_viewer/tracking_viewer.py

I executed
zed-sdk/object detection/birds eye viewer/python/object_detection_birds_view.py.

And find distance "0.0M" in "ZED| 3D View tracking" window when I stand 3.0 m distatnce.

tracking_viewer.py:127:                    text = "{:.1f}M".format(abs(obj.position[2] / 1000.0))

should be

tracking_viewer.py:127:                    text = "{:.1f}M".format(abs(obj.position[2]))

After that change I got about 3 m distance.

Steps to Reproduce

  1. change directory and run the script.
cd  zed-sdk/object detection/birds eye viewer/python
python object_detection_birds_view.py
  1. Have someone stand 3 meters in front of the camera.
  2. view "ZED| 3D View tracking" window, and check distance value.

Expected Result

about "3.0M" distance.

Actual Result

"0.0M"
