Three-dimensional thermal imaging for the detection of skin lesions and other natural and abnormal conditions

摘要

A thermal imaging system includes a data processing system and a geometrical scanning system constructed to communicate with the data processing system. The geometrical scanning system is adapted to scan at least a section of a surface of a subject under observation. The thermal imaging system also includes an infrared imaging system constructed to communicate with the data processing system. The infrared imaging system is adapted to image at least a portion of the section of the surface of the subject under observation. The data processing system is configured to receive data from the geometrical scanning system and to construct a surface map of the section of the surface of the subject under observation and to identify geometrical markers on the surface map based on the data from the geometrical scanning system. The data processing system is also configured to receive data from the infrared imaging system and to construct a thermal map of the portion of the section of the surface, to identify thermal markers on the thermal map based on the data from the infrared imaging system, and to register the thermal map to the surface map based on a correspondence between at least some of the geometrical and thermal markers. The data processor is configured to correct temperatures of the thermal map based on the surface map subsequent to the registering.
