Shape measuring device, program installed into this device, and recording medium storing this program

摘要

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).

1. A shape measuring device comprising:
a light receiving section that has an observation center axis extending toward an object; a light projecting section that irradiates the object with light obliquely from above; a three-dimensional shape data generating unit for processing a measurement image with a predetermined algorithm to generate three-dimensional shape data, the measurement image acquired in the light receiving section while the object is irradiated using the light projecting section; a 3D image generating unit for mapping a two-dimensional texture image of the object onto the three-dimensional shape data to generate a three-dimensional texture image, the two-dimensional texture image acquired in the light receiving section; a display section for displaying the three-dimensional texture image generated by the 3D image generating unit; and a control unit for executing the processes of
accepting a manipulation of a user to allow illumination by the light projecting section and acquire the measurement image in the light receiving section in synchronization with the illumination of the light projecting section,subsequently processing the measurement image with the predetermined algorithm to generate three-dimensional shape data,acquiring the two-dimensional texture image of the object in the light receiving section, andmapping the two-dimensional texture image onto the three-dimensional shape data to generate the three-dimensional texture image, wherein the user can select an application measurement mode capable of manually adjusting a variety of parameters related to capturing of the image of the object in the light receiving section, or a simple measurement mode capable of manually adjusting a smaller number of parameters than in the application measurement mode in terms of adjusting a variety of parameters related to capturing of the image of the object in the light receiving section.
