US Patent 9536355 Thermal detection in an augmented reality system

An augmented reality (AR) device comprises a transparent display, a thermal sensor, a depth sensor, and a processor. The thermal sensor generates thermal data related to physical objects detected by the AR device. A thermal baseline identification engine forms a thermal baseline using data from infrared imaging and depth profiling sensors, thermal data of the physical objects in a mapped 3D space, thermal context of the objects both spatially and based on their operating status, and their thermal parameters. A thermal anomaly identification engine identifies a thermal anomaly based on the established thermal baseline and the real time measurements, and generates a warning notification in response to the identified thermal anomaly.
