Title:
Form measuring apparatus
Document Type and Number:
Japanese Patent JP6029394
Kind Code:
B2
Abstract:
Provided is a shape measuring device capable of making a user to feel that three-dimensional shape data is easily acquirable. Right and left light projecting sections are individually turned on to automatically adjust exposure time or brightness of illumination so that an image displayed in a display section has the optimum brightness. Further, scanning is performed with a plurality of striped patterns using the light projecting section, and in synchronization therewith, a plurality of striped images are acquired by a camera. Subsequently, a 2D texture image of an object is acquired by using ring illumination or all-white uniform illumination of the light projecting section. A PC performs image processing and an analysis on the acquired image data with a measurement algorithm, to generate stereoscopic shape data. Further, a 3D texture image generated by mapping the two-dimensional texture image onto the stereoscopic shape data is displayed in a display section (monitor).
