Configure a Dual Stream Camera
A dual_stream
HTTP client camera combines the streams of two camera servers to create colorful point clouds.
One camera server streams a color stream and the other camera server streams a depth stream.
Navigate to the Config tab of your robot’s page in the Viam app.
Click on the Components subtab and click Create component.
Select the camera
type, then select the dual_stream
model.
Enter a name for your camera and click Create.
Edit and fill in the attributes as applicable.
