NODAR Viewer

nodar_viewer.webp

NODAR Viewer is a powerful and intuitive software tool designed to visualize and control stereo camera data. Tailored for professionals working with stereo vision systems, NODAR Viewer lets users view real-time camera streams, analyze depth data, and adjust camera settings. With its user-friendly interface and robust features, NODAR Viewer empowers users to unlock the full potential of stereo cameras in various applications, from robotics to automotive systems.

The viewer can be run on the Orin running Hammerhead or a separate computer connected to the Orin via 10G Ethernet. If run on the Orin that also runs Hammerhead, both the viewer and Hammerhead will compete for GPU resources and the frame rate will drop.

Data can be viewed in real-time from Hammerhead or replayed from disk.
