Problems solved by technology

The traditional shape error analysis report is in the form of a data report, which has a single form and cannot intuitively show where each point is located, the straightness, flatness, roundness, verticality, parallelism and deviation of the point cloud. Interpretation is often required by professionals, and it is difficult for non-professionals to understand

Embodiment Construction

[0014] Such as figure 1 Shown is a hardware architecture diagram of a preferred embodiment of the shape error analysis system of the present invention. The system includes a measuring machine 1, at least one workpiece 2, an application server 3, at least one application terminal 4 (only one is shown in the figure), and is connected to the measuring machine 1, the application server 3, and the application terminal 4 network5. Wherein, the network 5 may be an enterprise intranet (Intranet), the Internet (Internet) or other types of networks.

[0015] The measuring machine 1 in this embodiment can be an image measuring machine or a laser scanner. The measuring machine 1 is used to scan the measured element on the workpiece 2 to obtain point cloud data of the measured element, and the point cloud data is stored in a point cloud file. The point cloud file can be divided into CSV (Comma Separated Value, comma separated value) file, TXT (text) file and QVS file according to its st...

Abstract

The invention provides an analytical method for form error, including inputting the point cloud data of the measured factor of a work piece; setting up the analytical type, the tolerance, the point and line style of the point cloud data, carrying out geometric features fitting with the point cloud data and the best least squares according to the set-up analytical type so as to obtain the fitting figure; calculating the deviation between each point and the fitting figure; comparing the deviation with the set-up tolerance so as to determine whether the size of the work piece is qualified or not; and drawing the fitting figure into the point cloud figure according to the set-up point and line style and generates a graphic written report according to the point cloud figure, the calculated deviation and the result of the comparison. Additionally, the invention also provides an analytical system for form error.

Description

technical field [0001] The present invention relates to a shape error analysis system and method, in particular to a point cloud shape error analysis system and method technical background [0002] Quality is one of the important factors for an enterprise to maintain its long-term development ability. How to improve and ensure product quality is an important part of enterprise activities. In order to improve and ensure product quality, or research new products emerging in the market to assist the production and manufacturing process, companies often need to test some products. [0003] In the early stage of the inspection of the tested objects, specific inspection instruments were generally used, and the detection values ​​were determined after manual comparison. In recent years, with the improvement of computer hardware performance and the reduction of prices, computers have been introduced in large quantities in the inspection activities of the tested objects, thus improv...
