NODAR Viewer is a powerful, intuitive software tool for visualizing and controlling stereo camera data. Designed for professionals working with stereo vision systems, it enables real-time camera stream viewing, depth data analysis, and camera setting adjustments. Through its user-friendly interface and comprehensive features, NODAR Viewer helps users maximize the potential of stereo cameras across applications—from robotics to automotive systems.
You can run the viewer either on the Orin alongside Hammerhead or on a separate computer connected to the Orin via 10G Ethernet. Note that running both the viewer and Hammerhead on the same Orin will cause them to compete for GPU resources, resulting in reduced frame rates.
To launch the viewer, run nodar_viewer command in the terminal.
When you run the viewer for the first time, the application opens in its default layout:
When you modify the layout by resizing, opening, or closing viewers, the application will save your changes to ~/.config/viewer_config.yaml upon closing with the close button.
In the View menu, you can open or close the left properties panel. You can also use the Ctrl+Alt+P shortcut.
In the Layouts menu, you can select from several predefined UI layouts. The Base layout (shown in the image above) is selected by default.
The Viewers menu lets you open data visualizers. The image above shows four open viewers: two Rectified Image viewers, one Colorized Depth Map, and one Point Cloud.
