Abstract
A displacement detecting apparatus includes: a detector which detects displacement, which is spatial displacement over time, of each of a plurality of measurement points which have been set on an object, using a plurality of images of the object captured at a plurality of time points; an extractor which extracts characteristic displacement specific to the object, based on the displacement detected by the detector; and a calculator which calculates overall displacement indicating displacement of the entirety of the object, from the characteristic displacement extracted by the extractor.
Claims11
A displacement detecting apparatus, comprising:
- a detector which detects displacement of each of a plurality of measurement points which have been set on an object, using a plurality of images of the object captured at a plurality of time points, the displacement being spatial displacement over time;
- an extractor which extracts characteristic displacement specific to the object, based on the displacement detected by the detector;
- a calculator which calculates overall displacement indicating displacement of an entirety of the object, from the characteristic displacement extracted by the extractor;
- and
- a superimposed image generator which generates a superimposed image in which an image based on the displacement calculated by the calculator is superimposed onto at least one of the plurality of captured images.
A displacement detecting apparatus, comprising:
- a detector which detects displacement of each of a plurality of measurement points which have been set on an object, using a plurality of images of the object captured at a plurality of time points, the displacement being spatial displacement over time;
- an extractor which extracts one or more principal components through principal component analysis on the displacement detected by the detector;
- and
- a superimposed image generator which generates a superimposed image in which an image based on the one or more principal components extracted by the extractor is superimposed onto at least one of the plurality of captured images.
A displacement detecting method performed by a displacement detecting apparatus including a detector, an extractor, a calculator, and a superimposed image generator, the displacement detecting method comprising:
- detecting displacement of each of a plurality of measurement points which have been set on an object, using a plurality of images of the object captured at a plurality of time points, the displacement being spatial displacement over time, the detecting being performed by the detector;
- extracting characteristic displacement specific to the object, based on the displacement detected in the detecting, the extracting being performed by the extractor;
- calculating overall displacement indicating displacement of an entirety of the object, from the characteristic displacement extracted in the extracting, the calculating being performed by the calculator;
- and
- generating a superimposed image in which an image based on the overall displacement calculated in the calculating is superimposed onto at least one of the plurality of captured images.
