Abstract
A solution for evaluating an object using infrared data is provided. In particular, infrared data corresponding to the object is processed to enhance a set of signal features. The infrared data is analyzed to determine whether one or more anomalies are present.
Claims20
A method of evaluating an object for a heat related anomaly, the method comprising:
- processing, by a computer system including at least one computing device, infrared data corresponding to at least one side of the object to enhance a set of signal features in the infrared data and extract infrared data corresponding to at least a portion of the object from the infrared data, wherein the processing uses at least one enhancement process selected from a group of enhancement processes based on the at least one heat related anomaly, the group of enhancement processes including:
- segmentation, fusion of multiple infrared images in the infrared data, edge detection within an infrared image in the infrared data, applying thresholding to assign a pixel in the infrared data to white or black, and feature detection of the at least a portion of the object in the infrared data;
- analyzing the infrared data to determine a presence of the at least one heat related anomaly;
- and
- providing a result of the analyzing for use in an evaluation of the object.
