摘要： 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.

摘要： 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.
