How to save the wbp and dcfm after the calibration is done

[qilu67]

Hello,

Is there any way to save the wbp and dcfm parameters after the calibration is done? It seems like I have to do the calibration everytime I start the ROS driver of the camera. Thanks in advance.

Best regards, Qi

I haven't thought about it, since we mostly use monochrome cameras and don't really need to do the white balance / dark current calibration. But you're welcome to submit a PR if you come up with a way of doing it.

What I was thinking is changing the .cfg file in the bluefox2 package. But it seems like I can only see the options other than the parameters. Is the wbp and dcfm parameters stored somewhere else?

Sorry to bother again. I have another question regarding the publish rate of the image node. The camera that I am using is BF-MLC200wC. And I am running the single_node.launch and used rostopic hz to find out the publish rate of the /mv_xx/image_raw topics. However, the maximum rate I can get is around 50 Hz. Is there any setup should be done to get a higher rate from the camera?Thank you so much! Here is the settings that I am using

    <arg name="idpf" default="0"/>
    <arg name="aec" default="true"/>
    <arg name="expose_us" default="10"/>
    <arg name="agc" default="true"/>
    <arg name="gain_db" default="0.0"/>
    <arg name="acs" default="2"/>
    <arg name="cbm" default="0"/>
    <arg name="ctm" default="0"/>
    <arg name="dcfm" default="0"/>
    <arg name="hdr" default="true"/>
    <arg name="wbp" default="10"/>
    <arg name="request" default="0"/>
    <arg name="mm" default="0"/>
    <arg name="jpeg_quality" default="80"/>
