In the form measurement system which measures the size of the suffering

摘要

PPROBLEM TO BE SOLVED: To provide a shape measuring system, a shape measuring method, and a shape measuring program capable of calculating automatically a dimension such as a radius, a distance and an angle of a corner R in a specified portion requiring high dimensional precision. PSOLUTION: This shape measuring system of the present invention includes an outline shape image generating means for generating an outline shape image from a read-in outline shape data; an evaluation area setting means for setting the first evaluation area and the second evaluation area in a prescribed peripheral position of the measured objective portion found by executing geometrical pattern matching (called as PM in some cases) in the outline shape image; a measuring area setting means for setting a measuring area, using as a reference an intersection of two straight lines linear-approximated based on the outline shape data within the first evaluation area and the second evaluation area; and a shape evaluation means for finding a physical quantity of a geometric element in the outline shape data within the measuring area in response to a kind of set shape evaluation, and for executing prescribed dimension measuring processing.
