Zed Camera notes

Requires appropriate USB 3 ports: https://support.stereolabs.com/hc/en-us/articles/207635225-How-to-fix-USB-3-0-bandwidth-and-connection-issues

Extension cables that work: https://support.stereolabs.com/hc/en-us/articles/212542089-Can-I-use-the-ZED-camera-with-an-extension-cable

As IP Camera: https://www.stereolabs.com/docs/video/streaming/ -- streams using RTP. One PC can stream multiple cameras, so long as the GPUs can support them; or multiple machines can stream via a router. Jetsons (Nano, TX) can work with them. SDK supports both grabbing a camera and generating a stream, and also finding a stream and using it as an input. Very flexible!

Zed mini reports as Model "ZED-M". It supports 1344 x 376 @100 fps // 2560 x 720 @ 60fps // 3840 x 1080 @fps // 4416 x 1242 @15 fps
NOTE: the Zed mini camera usb port has a specific orientation: the "<<" symbol should face the front of the camera.
Requires SDK (includes drivers) from here: https://www.stereolabs.com/developers/release/
Requires CUDA https://developer.nvidia.com/cuda-downloads
Use to verify the camera is working. Can flip between different cameras. Can also use this to quickly record some material for the purposes of testing. Zed explorer also reports the camera calibration figures.
Can use this to quickly look at what the depth map looks like, as well as a textured point cloud. Generally the depth suffers from ripples, which get more problematic with evenly-coloured surfaces (not surprisingly). Increasing camera resolution to HD (at lower fps) reduces this a bit, but it certainly suffers more than the Kinect clouds. The camera also reports a "confidence" value per pixel, which can be used to filter down to the best points (mostly edges/features etc). Even at ~3m away I see some scatter that almost reaches +/-1m.
For a 1st-person perspective (zed-m mounted on headset) this wouldn't be so bad.
