Foxglove Studio

Foxglove Studio is an open source application developed by FoxGlove Technologies, Inc. It is part of the Robot Operating System (ROS) ecosystem and supports playback for MCAP recordings. You can download Foxglove Studio as well as our EdgeFirst plug-in for Foxglove and customized Raivin Foxglove layout

Topic names in layouts

Recordings made with Torizon for Maivin 2026.08 name their channels without the rt/ prefix used by earlier releases, for example /camera/h264 and /model/output. Layouts saved from older recordings need their panel topics updated, and the detection overlays now read the unified /model/output topic through the EdgeFirst plug-in. The Raivin layout linked above is configured for 2026.08 recordings.

Getting Started

Let's discuss how to install our custom plugins once you've installed Foxglove Studio.

Layout Features

The default Raivin layout includes:

• Top panel: H.264 camera stream with bounding box overlays
  • Shows detection results (i.e. the colored boxes around people when using a detection model)
  • Shows segmentation masks (i.e. the colored blobs covering detected objects when using a segmentation model)
• Bottom right panel: GPS coordinates map view
  • Interactive map with zoomable blue target showing camera position
• Bottom left panel: IMU sensor readings
  • Can be configured to show real-time plots
• Bottom timeline: Playback controls for navigation

Visualization Features

In the example above, we see both detection boxes and segmentation masks in the H.264 Camera topic.

Viewing Detection Messages

The detection boxes and the segmentation masks are contained in the /model/output topic, which the recorder captures by default. The EdgeFirst Foxglove plug-in draws them as image annotations over the camera stream.

Note

Not all vision models are able to produce detection results. The default model on the Raivin can produce both detection and segmentation results.

1. Record a MCAP file that captures the /model/output topic.

2. Confirm with the "Details" button that the newly recorded MCAP has a /model/output topic.

3. Download the file from the Raivin and load it in Foxglove Studio.

4. Click the "Settings" gear icon on the right side of the /camera/h264/ panel task bar.

5. The /model/output option should appear in the "Image annotations" dropdown menu in the "Image Panel" settings sidebar (bottom left of image below).

6. Enable the /model/output image annotations by clicking the closed eye icon. This will draw boxes around the detected objects.

Viewing Segmentation Messages

The segmentation masks travel in the same /model/output message as the detection boxes. Because of the amount of data included within this stream, the masks are not compatible with the default Image drawing API in Foxglove Studio, the EdgeFirst Foxglove plug-in must be installed to view segmentation masks in Foxglove.

The masks are drawn by the same /model/output image annotations as the boxes, enabling the annotations shows both.

Foxglove Detect Boxes Enabled

Viewing /radar/cube Messages

The radar cube is only published when cube streaming is enabled on the radar service. The Image panel in Foxglove can viewer can:

1. Record a MCAP file that has the /radar/cube message in it. See Maivin Dataset Recording for details.
2. Play the MCAP file in Foxglove Studio. See Playback MCAP with Foxglove Studio for details.

3. In the image panel, the /radar/cube topic should appear under the list of valid image topics.

4. Select the /radar/cube topic.

5. Change the color mode to Color Map, and select Turbo for the color map.
