It is now possible to run STS-PiLot on a Pi Zero (W) with live video. The latest software version contains an additional non-threaded video feed that puts less strain on systems with lower CPU specs.
Use the following URL syntax to use it:
http://[your pi's ip]:5000/?video=[msecs]
[msecs] sets the minimum delay between frame captures in milliseconds. Example:
http://192.168.1.23:5000/?video=100 will provide a video display with about 10 frames per second.
How does it work:
http://[your pi's ip]:5000/single_frame.jpg provides a single JPEG frame on every call to the URL.
This functionality is available in both the Pi Camera and the OpenCV generic camera interface.
You still get the threaded, high framerate, low latency, higher CPU interface when using the base URL without arguments: http://[your pi's ip]:5000
And this is the Polulu ZUMO chassis featuring a Pi Zero W with live camera feed and Explorer pHAT that had its first public appearance at Moray Coder Dojo yesterday:
