I'm trying to debug a problem with my Kinect not working right.
In the tutorial, there is a pretty standard way to view the camera stream: rosrun image_view image_view image:=/camera/rgb/image_color
Is there a similarly simple way to save a snapshot to disk?
Left clicking on the image in image_view will save a screenshot to the directory from which you started image_view in c-turtle and below. In Diamondback, you have to right click for this behavior; this prevents a lot of accidental frame grabs. :)
For example, if you were in /home/murph/code/topSecret in your terminal and you ran rosrun image_view image_view image:=/camera/rgb/image_color, the image would be saved in that directory.
Images are titled frame0000.jpg, frame0001.jpg, and so on.
To read more, visit the image_view wiki page.
Adding to @raphael favier 's answer, you can time capturing by:
term-1$ rosrun image_view image_saver image:=image_raw _save_all_image:=false _filename_format:=foo.jpg __name:=image_saver
Then only when you call the following, image files are generated:
term-2$ rosservice call /image_saver/save
Got a hint at start-jsk/jsk_apc/#9.
If you click on the picture in image_view, doesn't it save the picture?
Else, you can use image_saver in the image_view package.
rosrun image_view image_saver image:=[ your topic]
Raph
@raphael favier this rosrun gives me a infinite amount of image si there a way to just take one picture? and is there a way that i can put this in a code so when a publisher publishes something just then it take a picture?
