A browser application which uses the webcam of your device to map LED positions.

The Browser expects to be able to send commands through a websocket to turn on a series of LEDs one at a time. It takes a photo before and after turning the light on using a webcam and compares the two frames to calculate the x & y position within the camera frame.

The left hand image shows the camera feed and the right hand image shows the position of the LED marked with a red square.

Clone the repo

git clone https://github.com/met-office-lab/led-mapper.git

Run a web server and view the index.html page in a browser.

Dim the lights and point your webcam at the LED matrix you wish to map.

Watch the console output for a json object to be printed on completion.

Pro Tip: To run a simple web server in your current directory run python -m SimpleHTTPServer 8000 and visit http://localhost:8000 in your browser.
