Animal Stamp Rally Application using Image Recognition

Tokushima zoo is a municipal zoo housing a lot of animals for educational purpose. Thus, Tokushima city wants visitors to observe animals as many as possible whilst having fun. The animal stamp rally is a game that visitors collect a series of stamps at around animals which visitors have observed. Not to provide real stamps, tables and stamp cards, we develop an animal stamp rally application. Thanks to the Convolutional Neural Network (CNN), the application can recognize stamps from snapshots of real animals instead of real stamps or QR codes. Additionally, to improve animal recognition accuracy, the application uses GPS information. In this paper, we describes a progress of our development of the animal stamp rally application, and estimates its recognition accuracy.
