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.
Claims14
A strain amount calculation system comprising:
- an imaging unit that serially takes images of an object having a mechanoluminescent substance applied thereon;
- and
- a strain amount calculation device configured to acquire an image taken 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 information on the calculated strain amount.
A strain amount calculation method of calculating an amount of strain on an object based on luminescent brightness of a mechanoluminescent substance, the method comprising:
- serially taking images of the object;
- measuring luminescent brightness from an image taken by the image taking;
- 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 the strain amount calculated by the calculating.
A non-transitory readable storage medium that stores a program, the storage medium comprising the program configured to allow a computer to realize the following:
- an imaging function of serially taking images of an object having a mechanoluminescent substance applied thereon;
- a measurement function of measuring luminescent brightness from an image taken by the imaging function;
- a calculation function of 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 measurement function;
- and
- an output function of outputting the strain amount calculated by the calculation function.
