Dimension Measurement System, Estimation System, and Dimension Measurement Method

A dimension measurement method for measuring a dimension of a structure displayed as an image including a plurality of areas having different luminance, by using a dimension measurement system including a processor, a memory resource that stores data to be processed by the processor, and a display that displays a graphical user interface (GUI), the method comprising:

• setting a reference line for specifying a portion of boundaries between the plurality of areas and a reference point designated within any one of the plurality of areas, based on a manual operation by a user in the dimension measurement system, performed on the image of the structure displayed on the GUI;
• acquiring position information of the reference line and the reference point;
• and
• detecting a contour or edge of the structure by using the reference line and the reference point, and measuring the dimension of the structure by using information on the detected contour or edge.

A non-volatile recording medium having stored thereon a program for causing a computer to execute the following steps to measure a dimension of a structure displayed as an image including a plurality of areas having different luminance by using the computer equipped with a display that displays a graphical user interface (GUI):

• a step of setting a reference line for specifying a portion of boundaries between the plurality of areas and a reference point designated within any one of the plurality of areas, based on a manual operation by a user in a dimension measurement system, performed on the image of the structure displayed on the GUI;
• a step of acquiring position information of the reference line and the reference point;
• a step of detecting a contour or edge of the structure, by using the reference line and the reference point;
• and
• a step of measuring the dimension of the structure by using information on the detected contour or edge.
