Abstract
A shape evaluation method according to the present invention comprises: a shape error calculation step that calculates a shape error, which is an error between a designed shape and a shape to be evaluated; and a visible error detection step that detects visible shape errors on the basis of the shape error and predetermined visual characteristic data.
Claims7
A shape evaluation method for evaluating a shape on a surface of a target object, the shape evaluation method comprising:
- a step of storing design data to which a design shape configured during designing of a target object is set;
- a step of storing evaluation target data to which an evaluation target shape which is a target of evaluation of the target object is set;
- a shape error calculation step of calculating a shape error on the basis of the design shape and the evaluation target shape;
- a visible error detection step of detecting a visible shape error from the calculated shape error on the basis of the shape error calculated in the shape error calculation step and visual characteristic data defined in advance;
- and
- a step of identifying a position where a visible shape error occurs.
A shape evaluation device for evaluating a shape on a surface of a target object, the shape evaluation device comprising:
- a design data storage part for storing design data in which a design shape configured during designing of the target object is set;
- an evaluation target data storage part for storing evaluation target data in which an evaluation target shape being a target of evaluation of the target object is set;
- a shape error calculation part for calculating a shape error on the basis of the design shape and the evaluation target shape;
- a visible error detection part for detecting a visible shape error from calculated shape error on the basis of the shape error calculated by the shape error calculation part and visual characteristic data defined in advance;
- and
- a position identifying part for identifying a position where the visible shape error occurs.
