Abstract: An image of a measurement object is displayed, and specification of a feature image and a measurement position is received on the displayed image. The feature image, the specification has been received, and information on relative positions for the feature image, which represents the measurement position and a display position of a dimension line, are stored. A newly acquired image of the measurement object is compared with the feature image to identify information on the attitude and the position of the image of the measurement object. A measurement position is set for the image of the measurement object with the identified attitude and position, and then predetermined physical quantities are measured. Based on the stored information on the relative position for the feature image displaying the dimension line, a dimension line indicating a measurement position and a measurement result are displayed at predetermined positions.

Abstract: A shape of a measurement object is measured based on an image obtained by applying light onto a stage having the measurement object mounted thereon and performing image formation of transmitted light or reflected light of the light on an imaging device. An image of the measurement object that is obtained by image formation on an imaging device is displayed within the range of the field of view, and feature quantity information is extracted based on the image of the measurement object. A determination is made as to whether feature quantity information approximately in agreement with the extracted feature quantity information is stored. If it is determined that the feature quantity information approximately in agreement with the extracted feature quantity information is stored, then the shape of the measurement object is measured based on information on measurement conditions stored in association with the feature quantity information.
