We cooperate with Airport Authority Hong Kong (HKAA) on a smart airport project. One major item is a smart patrol robot. Currently, the robot is used to identify out-of-order lamp bulbs in the airport. However, the robot can be applied to perform other operations in the future. HKAA has agreed to lend us two smart patrol robots with cameras atop for testing and implementation. After several rounds of discussion, below are some possible directions: – Applications that involve object recognition (e.g. recognition of fluid on the floor) – Applications that involve facial recognition (e.g. Kiosk) – Path finding and collision avoidance – Sensor data post-processing (e.g. utilizing temperature and video data for interesting applications).
