Abstract
A method includes capturing an image, and performing region detection on the captured image. The region detection includes identifying an object represented in the captured image. The method further includes detecting emissivity of the identified object and determining the temperature of the object based on the detected emissivity of the object.
Claims22
A method, comprising:
- capturing an image;
- performing region detection on the captured image, said region detection including identifying an object represented in the captured image;
- detecting emissivity of the identified object;
- and
- determining a temperature of the object based on the detected emissivity of the object;
- wherein said detecting step includes looking up emissivity data from an emissivity data store based on a result of identifying said object.
3 more elements
An optical temperature-detection apparatus, comprising:
- a wavelength splitter;
- a digital camera oriented to capture an image of an object through the wavelength splitter;
- a signal processing unit in communication with the digital camera to receive image data from the digital camera;
- and
- an emissivity data storage unit in communication with the signal processing unit to supply emissivity data to the signal processing unit.
2 more elements
An optical temperature-detection apparatus, comprising:
- a digital camera;
- a processor coupled to the digital camera to receive image data from the digital camera;
- and
- a memory in communication with the processor, the memory storing program instructions, the processor operative with the program instructions to perform functions as follows:
- performing region detection on an image represented by the image data, said region detection including identifying an object represented in the image;
- detecting emissivity of the identified object;
- and
- determining a temperature of the object based on the detected emissivity of the object;
- wherein said detecting function includes looking up emissivity data from an emissivity data store based on a result of identifying said object.
