Specify number of detections

[hsaleem1]

Hi there,

Can somebody please guide me that how can we limit the number of detection after running the launch file? As the output is providing repeated and continuous values.

Thanks.

Hi @hsaleem1
This package doesn't provide a parameter for doing this. So, I can think of different things:

• Change the source code adapting it to your needs (maybe it's not the most advisable).
• To write other node which subscribes to the 3d bounding boxes and finalize when you want. Obviusly, darknet_ros_3d will follow working even if you don't need it until you kill it.
• The last option is the same that the previous one but in your custom node you can execute a "kill -9" signal over de pid of darknet_ros_3d process. In this way, your computer will not waste resources when you are not using darknet_ros_3d.

@fgonzalezr1998, can you please further guide about the third point? I mean how can I execute "kill - 9" signal?

@hsaleem1 You can use the "system" function from stdlib to execute a "pkill [process_name]" (where process_name" is the process name of darknet_ros_3d). I think it will be "darknet_ros_3d_node" but you can see it with htop or ps. I recommend you to consult its man page.

Also, you can execute a fork() + exec() instead of system(). It provides a greater control over the process son but in this case may be you don't have to.
