Abstract:
An infrared (IR) scanning system for performing 3D temperature sensing and 3D shape construction of an object, comprising:an IR detecting mechanism containing a plurality of IR detectors for detecting radiation energy from the object in different angles and converting the radiation energy so measured into an electrical signal; and a signal decoding mechanism for receiving the electrical signal, editing and integrating the signal into data of a 3D profile curved surface and a corresponding temperature distribution of the object; wherein the IR detecting mechanism further comprises a movable device connected to the plurality of IR detectors to adjust scanning positions of the plurality of IR detectors around the object, the plurality of IR detectors and the movable device are arranged such that a 3D geometrical model of the object can be directly reconstructed when the movable device moves along the object; and the signal decoding mechanism comprises a computer and a processing software capable of converting the signal detected by the plurality of IR detectors into temperature data and calculating, integrating, and editing the data according to the scanning positions of the plurality of IR detectors to simultaneously form the 3D geometrical model and the corresponding temperature distribution of the object.
