Abstract: A stress analysis device for moving body, includes: an infrared camera that captures an infrared image of a moving body while making a relative movement with respect to the moving body; and an image processing unit that performs image processing on a plurality of the infrared images captured by the infrared camera. 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.

Abstract: A stress distribution measurement method is a method of measuring stress distribution generated on a structural object including two support parts and a beam part provided between the support parts. The method includes: generating first image data by performing, through a first image capturing unit, image capturing of a moving object or an identification display object attached to the structural object from the moving object; calculating, based on the first image data, a movement duration in which the moving object moves between the support parts; generating, as second image data, thermal image data by performing image capturing of the surface of the beam part through a second image capturing unit; calculating a temperature change amount based on a second image data group corresponding to the movement duration; and calculating a stress change amount based on the temperature change amount to calculate stress distribution based on the stress change amount.
