Abstract
A method and system for detecting concealed objects using a handheld thermal imager is disclosed. In a particular embodiment, the method includes capturing thermal sensor data from the handheld thermal imager, transmitting the thermal sensor data to a processor, and formatting the sensor data using the processor. The method also includes identifying a pre-determined relative difference between a temperature of a subject and a background scene and isolating the subject of interest from the background scene in the thermal sensor data using the processor. In addition, the method includes detecting a deviation in the temperature within a discrete area to suggest a size and location of the concealed object on the subject and filtering the thermal sensor data to generate a visual image displaying the concealed object on the subject of interest.
