An image conversion system and method read image data of a two-dimensional image from a storage system. A data format, an image size, a pixel value of each pixel, and pixel coordinates of each pixel are determined according to the image data. A gray value of each pixel is calculated. According to the pixel coordinates and gray value of each pixel, a three-dimensional mesh is generated and then decorated, so that a three-dimensional image is obtained.

A method for correcting an image of a physical object first captures images of a circle and a rectangle set of a calibration plate placed on a measurement machine, and determines correction data using the images of the circle and the rectangle. The method further corrects the image of the physical object captured by the measurement machine according to the correction data, and displays a corrected image of the physical object.

A computer is connected to a measurement machine. The computer receives an area selected by a user of a three-dimensional model of a workpiece which is put on the measurement machine. A first size of the selected area is calculated corresponding to resolution values of various images of the workpiece captured by a charge-coupled device (CCD). The computer calculates a number of the images which are necessary to create a complete bitmap, of a certain second size, by splicing together the various images. Coordinate values of the pixel points of the various images are calculated according to a splicing type desired and set by the user. The computer puts the pixel points into a mapping relationship according to the coordinate values of the pixel points, to create the complete bitmap.

A measuring device and method is used to select focusing points on an object. A CCD of the measuring device is positioned at the top of an initial focusing range, then moves to the bottom of the initial focusing range at a first speed to capture first images of the object. Image points corresponding to each focusing point in the first images are identified to compute coordinates of a first focal point of each focusing point. The initial focusing range is updated according to Z-coordinates of the first focal points. The CCD is positioned at the bottom of the updated focusing range, then, moves to the top of the updated focusing range at a second speed to capture second images of the object. Image points corresponding to each focusing point in the second images are identified to compute coordinates of a second focal point of each focusing point.
