Revisiting Multiple Pattern Recognition Using the FLARMultiMarkerDetector and an iPhone

I was able to revisit the spaghetti code on my FLARMultiMarkerDetector prototype and improve performance 100 fold. Thanks to the guys at for sharing their source for the virtual drum kit.

Here’s a post explaining their demo.

Here’s a link to their source.

The MD2 models I’ve been using should be familiar by now and are from Polycount.

I was writing this app on the train and didn’t have a printer to print the patterns. Now I have them on my iPhone, so I can test my Flar apps where ever I happen to be.

One thing I’ve noticed, is that if you cutting the patterns out or are displaying them on an iPhone it seems you have to leave a white margin in addition to the black border for the pattern to be recognized.
