1. A stress analysis device for a moving body, comprising:
an image processing unit that performs image processing on a plurality of nfrared images of the moving body captured by an infrared camera while making a relative movement with respect to the moving body, wherein:
the image processing unit includes:
an alignment unit that aligns portions of an object included in the moving body in the plurality of the infrared images including the object, and
a stress distribution calculation unit that calculates temperature changes of each of the portions of the object to obtain stress distributions of the portions of the object based on the temperature changes,
the alignment unit divides one infrared image into a plurality of frames,
the alignment unit aligns the portions of the object on the plurality of frames in the plurality of the infrared images, and
the alignment unit specifies frames common to the plurality of frames in the plurality of the infrared images.
