Abstract
A measurement method includes a generation step, a region detection step, an image display step, a point input step, and a measurement step. Three-dimensional image data including three-dimensional coordinates of two or more points on a subject are generated in the generation step. Two or more feature regions on the subject are detected on the basis of the three-dimensional image data in the region detection step. An image of the two or more feature regions is displayed on a display in the image display step. A point on the subject is accepted through an input device in the point input step. A size of the subject is measured on the basis of three-dimensional coordinates of two or more points on the subject.
Claims15
A measurement method executed by a processor, the measurement method comprising:
- a generation step of calculating three-dimensional coordinates of two or more points on a subject on the basis of a two-dimensional image of the subject and generating three-dimensional image data including the three-dimensional coordinates of the two or more points;
- a region detection step of detecting two or more feature regions on the subject on the basis of the three-dimensional image data,
- wherein a three-dimensional shape of the subject has a common feature in each of the two or more feature regions;
- an image display step of displaying an image of the two or more feature regions on a display so that the two or more feature regions are visually distinguished from each other;
- a point input step of accepting a point on the subject through an input device after the image display step is executed and generating point information indicating the accepted point;
- and
- a measurement step of measuring a size of the subject on the basis of three-dimensional coordinates of two or more points on the subject including the point indicated by the point information.
