Abstract
A monitoring device is a monitoring device of a material testing machine including a display having a marker on a display panel. The monitoring device includes: an acquisition unit that acquires a photographed image of a camera that photographs the display panel; a first generation unit that generates a first processed image obtained by gray-scaling the photographed image; a second generation unit that generates a second processed image obtained by performing blur processing on the first processed image; a third generation unit that generates a third processed image obtained by binarizing the first processed image based on the second processed image; and a first detection unit that detects the marker from the third processed image.
Claims6
A monitoring device of a material testing machine including a display panel having a display area including a first display that displays a test value and/or a test state, and a non-luminescent marker on the display panel, wherein
- the non-luminescent marker is attached to the display panel in correspondence with the display area,
- the monitoring device comprises a processor that is configured to:
- acquire a photographed image of a camera that photographs the display panel;
- generate a first processed image obtained by gray-scaling the photographed image;
- generate a second processed image obtained by performing blur processing on the photographed image;
- generate a third processed image obtained by binarizing the first processed image based on the second processed image;
- detect the non-luminescent marker from the third processed image;
- generate an extracted image by extracting the display area, from the photographed image, corresponding with the non-luminescent marker based on the non-luminescent marker detected;
- and
- display a determination result of the test value and/or the test state on a second display of the monitoring device based on the extracted image generated.
A monitoring system including a monitoring device of a material testing machine including a display area including a first display that displays a test value and/or a test state, and a display panel having a non-luminescent marker on the display panel, and a camera photographing the display panel, wherein
- the non-luminescent marker is attached to the display panel in correspondence with the display area,
- the monitoring device includes a processor that is configure to:
- acquire a photographed image of the camera that photographs the display panel;
- generate a first processed image obtained by gray-scaling the photographed image;
- generate a second processed image obtained by performing blur processing on the photographed image;
- generate a third processed image obtained by binarizing the first processed image based on the second processed image;
- a detect the non-luminescent marker from the third processed image;
- generate an extracted image by extracting the display area, from the photographed image, corresponding with the non-luminescent marker based on the non-luminescent marker detected;
- and
- display a determination result of the test value and/or the test state on a second display of the monitoring device based on the extracted image generated.
