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： In a method for measurement of flatness of objects on a measuring machine, at least two objects are fixed on a worktable of the measuring machine. The method establishes a first coordinate system for the worktable location, sets two groups of horizontal scanning points for each object, and sets two groups of vertical scanning points for each object. By controlling at least two laser heads of the measuring machine, the objects are measured and coordinate values for each of the points scanned are obtained. The method calibrates a first coordinate system and establishes a second coordinate system based on the first coordinate system. In the second coordinate system, the at least two laser heads measure the objects and obtain data, and an indication of the flatness of each object is calculated and displayed on a display device.

摘要： In a method for processing a point cloud using a computing device, a straight line fitted by the point cloud comprising border points is determined as a benchmark line. An inflection point in the point cloud of the benchmark line is determined. If the vertical distance of the inflection point is not greater than the preset filtration value, needless border points in the point cloud are deleted and a remainder point cloud is obtained. If the vertical distance between the inflection point and the benchmark line is greater than a filtration value, the point cloud is divided into two sub-point clouds, and the one sub-point cloud having border points less than the preset number is deleted, and the other sub-point cloud is set as a remainder point cloud.
