Abstract
A surface performance evaluation device including memory and a processor coupled to the memory. The processor being configured to: acquire a captured image, which is a moving image of a test object on which a liquid is dispersed, and which is captured by a camera; quantify, based on the captured image that is acquired by the processor, a degree of diffusion of the liquid that is dispersed on the test object and diffuses; and evaluate a surface performance of the test object based on an index quantified by the processor.
Claims5
A surface performance evaluation device comprising memory and a processor coupled to the memory, and the processor being configured to:
- acquire a captured image, which is a moving image of a test object on which a liquid is dispersed, and which is captured by a camera;
- quantify, based on the captured image that is acquired by the processor, a degree of diffusion of the liquid dispersed on the test object as a frequency distribution for each direction in which the liquid diffuses, and further calculate a vertical/horizontal component ratio of the test object according to the frequency distribution;
- and
- evaluate a surface performance of the test object based the vertical/horizontal component ratio.
A surface performance evaluation method executed by a processor for evaluating a surface performance, the surface performance evaluation method comprising:
- acquiring a captured image, which is a moving image of a test object on which a liquid is dispersed, and which is captured by a camera;
- quantifying, based on the captured image that is acquired, a degree of diffusion of the liquid dispersed on the test object as a frequency distribution for each direction in which the liquid diffuses, and further calculating a vertical/horizontal component ratio of the test object according to the frequency distribution;
- and
- evaluating a surface performance of the test object based on the vertical/horizontal component ratio.
A non-transitory computer-readable recording medium storing a surface performance evaluation program executable by a processor to perform processing, the processing comprising:
- acquiring a captured image, which is a moving image of a test object on which a liquid is dispersed, and which is captured by a camera;
- quantifying, based on the captured image that is acquired, a degree of diffusion of the liquid dispersed on the test object diffuses, and further calculating a vertical/horizontal component ratio of the test object according to the frequency distribution;
- and
- evaluating a surface performance of the test object based on a the vertical/horizontal component ratio.
