[Humble] Acquisition and Trigger

[li-dahua]

#How can I adjust these parameters in sync launch code? Thank you

There are three acquisition modes:

Continuous - acquires images continuously. This is the default mode.

Multi Frame - acquires a specified number of images before stopping acquisition.

Single Frame - acquires 1 image before stopping acquisition.

System details

• operating system/version: ubuntu 22.04
• ROS version[Humble]): Humble
• complete FLIR camera model (e.g. BFS-U3-04S2C-C):BFS usb

Changing the acquisition mode is not directly supported for the blackfly S cameras. However, you can implement it easily yourself by modifying the blackfly_s.yaml configuration file. Follow the instructions in the README on how to add your own ros parameters, e.g. call it "acquistion_mode". Then you should be able to specify it at launch time by setting your newly created ROS parameter.
The other alternative is defining a user set with SpinView, and then loading that parameter set in your launch file by setting the correct ROS parameters.
I personally would choose the first option.
