Abstract
A strain amount calculation system includes an imaging unit, and a strain amount calculation device that acquires an image taken by the imaging unit, measures luminescent brightness from the acquired image, calculates an amount of strain on the object caused by a load on the object, based on a temporal change in the measured luminescent brightness, and outputs information on the calculated strain amount.
Claims8
A strain amount calculation system comprising:
- an imaging unit configured to capture a plurality of sequential images of an object having a mechanoluminescent substance applied to the object;
- and
- a strain amount calculation processor configured to:
- acquire an image of the plurality of sequential images captured by the imaging unit,
- measure luminescent brightness from the acquired image,
- calculate an amount of strain on the object caused by a load on the object, based on a temporal change in the measured luminescent brightness, and
- output an image of the object illustrating the calculated amount of strain on the object as a rendered color contour map on the object.
A strain amount calculation method to calculate an amount of strain on an object based on luminescent brightness of a mechanoluminescent substance, the method comprising:
- capturing a plurality of sequential images of the object;
- measuring luminescent brightness from an image of the plurality of sequential images;
- calculating an amount of strain on the object caused by a load on the object, based on a temporal change in the luminescent brightness measured by the measuring;
- and
- outputting an image of the object illustrating the calculated amount of strain on the object as a rendered color contour map on the object.
A non-transitory readable storage medium having stored therein a program, the program causing a computer to:
- capture a plurality of sequential images of an object having a mechanoluminescent substance applied thereon;
- measure luminescent brightness from an image of the plurality of sequential images;
- calculate an amount of strain on the object caused by a load on the object, based on a temporal change in the luminescent brightness measured by the measurement function;
- and
- output an image of the object illustrating the calculated amount of strain on the object as a rendered color contour map on the object.
