摘要： A system and method for determining inflection points in an image of an object includes obtaining the image of the object, performing binary image processing on a border of the image to obtain border points, selecting a predetermined number of the border points to fit a straight line, calculating a vertical distance between each selected border point and the straight line, and obtaining a total distance. The method further includes adding a new border point to the selected border points if the total distance is less than a predetermined value, so as to fit a new straight line and do a loop cycle, otherwise, regarding a last border point of the selected border points as an inflection point, and sequentially selecting the predetermined number of other border points to fit another new straight line.

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.

摘要： A scanner obtains point-cloud data of adjoining parts of a product. A computing device reads two point-clouds from the point-cloud data, fits two or more lines according to the two point-clouds, selects two lines that have the same ascending direction from the two or more lines, and creates a two-dimensional coordinates system base on the two selected lines. The computing device determines a highest point in each of the two point-clouds based on distances from each point in either of the point-clouds to a corresponding selected line, and determines two nearest points in the two point-clouds. A difference between Y coordinates of the two highest points is determined as a gap-height of two adjoining parts of the product, and a difference between X coordinates of the two nearest points is determined as a gap-width between two adjoining parts.
