Hello @engcang ,

Thank you for sharing this project
I'm trying to use ros-sort , but each time I try to echo the /tracked_boxes topic I get the following error

rosrun package_name ros-sort.py _/display:=True

.009844064712524414

raise ROSSerializationException(str(e))
rospy.exceptions.ROSSerializationException: field bounding_boxes[].xmin must be an integer type

EDIT the error triggers immediately or sometimes after 30 seconds and . Even if darknet_ros correctly detects the class ( person in this case) , the field bounding box stay always empty :
image_header:
seq: 0
stamp:
secs: 0
nsecs: 0
frame_id: ''
bounding_boxes: []
I am using python3 on ROS, maybe some statement not compatible with Python3 ?

Could you please help to find a solution ?
Thanks

Hi,

I encounter make error on jetson xavier nx

ros-yolov3-sort/SORT/cpp_ubuntu/build$ cmake .. && make
......

It seems CV_WINDOW_NORMAL not deifned, where should I add the define?

hi @engcang

great implementation.
just saying I cant wait to see the full implementation of ROS - C++.

Thank you

This error will be reported when I run the general yolov3.launch file under ROS. Before running, I change it to USB under ros.yaml file_ Cam topic name, also added weight file and configuration file, yolov3.yaml. Is there anything else to change? Could you tell me the specific steps before running the. Launch file? Thank you very much and look forward to your reply.

Will this ros sort c++ version run on ros now?
Thanks I want change python to c++

When I try to compile i found the following error
"OpenCV 4.x+ requires enabled C++11 support"
