Patent ID: 8045791

Claim:
A system for measuring digital images of a workpiece, the system comprising a client computer for measuring the digital images, the client computer comprising an image merging module, a selecting module, an image extracting module, and a measuring module, wherein: the images merging module is configured for merging all the digital images in a source file to generate a combined image of the workpiece according to center point coordinates of each of the captured images; the images merging module comprising a logic rectangle generating sub-module configured for generating a pixel rectangle rcB for each of the images according to height and width of the images, merging all the pixel rectangles rcB according to the center points coordinates measured in a pixels unit to generate a logic rectangle rcA, and generating an image rcC by reducing the logic rectangle rcA by a reduction scale S and a coordinate mapping, wherein the reduction scale S is the greater one of a length of the logic rectangle rcA divided by the length of the pixel rectangle rcB or a width of the logic rectangle rcA divided by the width of the pixel rectangle rcB; the selecting module is configured for selecting an object to be measured on the combined image; the image extracting module is configured for extracting an image of the selected object from the combined image; the measuring module is configured for measuring the selected object on the extracted image; and the client computer connects to a measuring computer for downloading the digital images.
