Patent ID: 8885176

Claim:
A shape measuring device comprising: a stage on which a measuring object is mounted; a light projecting unit configured to irradiate the measuring object mounted on the stage with light obliquely from above; a light receiving unit arranged above the stage and configured to receive the light reflected by the measuring object mounted on the stage and output a light receiving signal indicating a light receiving amount, and to image the measuring object mounted on the stage; a data generating unit configured to generate stereoscopic shape data indicating a stereoscopic shape of the measuring object by a triangular distance measuring method based on the light receiving signal output by the light receiving unit; a display section for displaying an image of the measuring object captured by the light receiving unit; an operation unit operated by a user to specify an arbitrary position on the image of the measuring object displayed on the display section; a relative distance changing unit for changing a relative distance between the light receiving unit and the stage so that a portion of the measuring object corresponding to the position specified by the operation unit coincides with a focus of the light receiving unit at the time of focusing operation; and a control section for controlling the light projecting unit to irradiate the measuring object with light with the portion of the measuring object corresponding to the position specified by the operation unit positioned at the focus of the light receiving unit, and controlling the data generating unit to generate the stereoscopic shape data indicating the stereoscopic shape of the measuring object by the triangular distance measuring method based on the light receiving signal output by the light receiving unit at the time of shape measurement.
