Problems solved by technology

It can be seen from Figure 1 that the format of this report is relatively simple, and it cannot intuitively show the specific position of each point, and the straightness and tolerance of the straight line often need to be interpreted by professionals, which is difficult for non-professionals to understand

Embodiment Construction

[0017] Referring to FIG. 2 , it is a hardware architecture diagram of a preferred embodiment of the straightness analysis system of the present invention. The system includes a measuring machine 1 , an application server 2 , a network 3 , at least one application terminal 4 (only one is shown in the figure) and a database 5 . The measuring machine 1 is used to scan the measured element on the part, and obtain the point cloud data of the measured element. The so-called point cloud refers to a set composed of a plurality of discrete points. The database 5 stores the point cloud data obtained by the measuring machine 1 as corresponding point cloud files, which can be stored as CSV (Comma Separated Value) files, TXT (text) files or QVS files, for different application terminals 4 to carry out choose. The application server 2 includes a plurality of functional modules for performing straightness analysis on point cloud data and drawing straightness analysis graphs. The applicatio...

Abstract

The method comprises: receiving point-clouds data; receiving the parameter set by user; making straight line fit for the point-clouds data to find out linear equation; calculating the bias value between each point in the point-clouds to said straight line; calculating the linearity of the straight line; calculating the feature point and coordinate value of the trend line composed of all points in the point-clouds; according to said parameter, point-clouds data, the linear equation, bias value, linearity of the straight line, and feature point and coordinate value, drawing the linearity-analyzed chart.

Description

technical field [0001] The invention relates to an error analysis system and method, in particular to a straightness analysis system and method. Background technique [0002] Straightness is the degree of non-straightness of the measured features on the control part. Straightness analysis can be the straightness analysis of plane straight lines, or the straightness analysis of straight lines in three-dimensional space, which is very commonly used in the field of precision measurement. The traditional straightness analysis report is in the form of a data report, as shown in Figure 1, which is a straightness analysis report of a straight line in a three-dimensional space. The figure describes the coordinates of ten points on a straight line on the x-axis, y-axis, and z-axis. The straightness analysis report of a plane line is similar to this, the difference is that the coordinate value of each point on the z-axis is 0. It can be seen from Figure 1 that the format of this re...
