Data display with Rviz RVIZ is a ROS graphical interface that allows you to visualize a lot of information, using plugins for many kinds of available topics. The zed_display_rviz package provides two launch files (display.launch and display_zedm.launch) that run two preconfigured RVIZ sessions for the ZED and ZED-M cameras respectively. The two sessions load the default RVIZ plugins preconfigured to show the most used data from the ZED ROS infrastructure. To create your own RVIZ configuration, you can use the plugins described below. Global options To be able to visualize the information published by the ZED camera, it is necessary to correctly configure the Global Options: Key parameters: Fixed frame: Indicates the name of the frame used as reference for all the other frames. You can select every frame available in the combo box. map or odom are the best choices. Frame rate: The maximum frequency used to update the 3D view. 30 or 60 FPS are good values. Available computational power should guide your decision. Grid This plugin allows you to visualize a grid normally associated with the floor plane. Key parameters: Reference frame: The frame used as reference for the grid coordinates (normally: <fixed_frame>) Plane cell count: The size of the grid in cells Normal cell count: The number of cells in the direction normal to the grid plane (normally: 0) Cell size: Dimensions in meters of each grid cell Plane: The two axes that identify the grid plane Robot model This plugin allows you to visualize the Robot Model according to its description from the URDF model. With the ZED wrapper, you can load two Robot/Camera models for the two Stereolabs cameras: zed.urdf and zedm.urdf Key parameters: Visual enabled: Enable/disable the 3D visualization of the model Robot description: The topic on which the robot description is published. From zed_camera.launch: <remap from="robot_description" to="zed_description" /> By expanding the Links voice, you can see the whole model tree, with all the joints and the links available and the relative position and orientation in the space relative to the fixed frame. TF This plugins allows you to visualize the position and the orientation of all the frames that compose the TF Hierarchy. Key parameters: Show names: Enable/disable the 3D visualization of name of the links Show axes: Enable/disable the 3D visualization of the axes of the frames Show arrows: Enable/disable the 3D visualization of the arrows that connect the various frames Update interval: The update time in seconds. Leave at 0 to see each update Critical to using this plugin is the ability to enable/disable visualizing individual frames. This allows you to concentrate only on the parts that are most important for your current task.
