Subscribed Topics image ( sensor_msgs/Image)ĭisparity_view Simple viewer for stereo_msgs/DisparityImage topics. Image_view Simple image viewer for ROS sensor_msgs/Image topics. As with image_view, you can specify an image transport to use for the left and right image as an optional argument. By default, images will be saved as left0000.jpg, right0000.jpg, disp0000.jpg, left0001.jpg, right0001.jpg, disp0001.jpg. You may save the current image pair by right-clicking on any display window. Rosrun image_view stereo_view stereo:= image:=įor example, to view stereo image pairs on topics /my_stereo_cam/left/image_rect_color and /my_stereo_cam/right/image_rect_color, use: rosrun image_view stereo_view stereo:=/my_stereo_cam image:=image_rect_color Note that this is merely shorthand equivalent to setting the ~image_transport parameter: rosrun image_view image_view image:=/camera/image _image_transport:=theora For example, if theora_image_transport is built on the publisher's side, you can use theora transport: rosrun image_view image_view image:=/camera/image theora If you want to view a compressed image stream (usually a good idea over wireless!) using the capabilities of image_transport, specify the transport type as a command-line argument. By default, images will be saved as frame0000.jpg, frame0001.jpg. You may save the current image by right-clicking on the display window. Rosrun image_view image_view image:= įor example, to view raw images on the topic /camera/image, use: rosrun image_view image_view image:=/camera/image The string argument is "left" or "right". Use to control name, location and format of saved images. printf-style format for saved image names.~filename_format ( string, default: "%s%04i.jpg")

Whether the windows should autosize to the image or be resizeable by the user.

Parameters ~autosize ( bool, default: true)

The disparity image computed from the left/right stereo pair.

Formal parameters stereo and image should be remapped appropriately. Subscribed Topics /left/ ( sensor_msgs/Image) Shows the left/right image pair and the disparity image (color-mapped) computed from them. ~window_name ( string, default: name of the image topic) image_view allows you to specify this as a simple command-line argument for convenience. ~image_transport ( string, default: "raw") ~filename_format ( string, default: "frame%04i.jpg")

Whether the window should autosize itself to the image or be resizeable by the user.

Parameters ~autosize ( bool, default: false) Should be remapped to the name of the real image topic. Subscribed Topics image ( sensor_msgs/Image) Image_view Simple image viewer for ROS topics. By default, images will be saved as left0000.jpg, right0000.jpg, left0001.jpg, right0001.jpg.

You may save the current image pair by left-clicking on either display window. Stereo_view also shows the disparity image computed from the stereo pair, color-mapped for clarity. Note that this is merely shorthand equivalent to setting the ~image_transport parameter: image_view image:=/camera/image _image_transport:=theoraįor example, to view stereo image pairs on topics /my_stereo_cam/left/image_rect_color and /my_stereo_cam/right/image_rect_color, use: stereo_view stereo:=/my_stereo_cam image:=image_rect_color For example, if theora_image_transport is built on the publisher's side, you can use theora transport: image_view image:=/camera/image theora You may save the current image by left-clicking on the display window.
