Over at MathWorks’ MakerZone, Eric Wetjen has written a tutorial/article in which he shows a way of using a webcam to count cars on a highway. The webcam captures images and then they use Simulink to analyse the images. The data is then sent to IoT service ThingSpeak and then analyse the data further using MATLAB. It’s quite complicated, and does have some (well-documented) flaws but it’s a good proof-of-concept. Read more here.
