We’ve seen some projects in the past which display patterns or games on an LED matrix, but they’re not nearly as complex as this project. Using a webcam, a video stream is processed via MatLab for edge detection and the results are displayed images on the LED matrixly from a webcam. Each frame from the webcam stream is rendered using only 50 lines of code.
The program captures a frame, sizes it, converts the frame to black and white for accurate edge detection, then compresses the image data before transmitting it to an embedded processor. The webcam stream is displayed LED-style at around 42 Hz. Follow the project details and setup some interesting animated LED shows.
