Problems solved by technology

However, the traditional analysis report of the roundness calculation results is in the form of a data report, and its content is relatively simple. It cannot intuitively display the error status of each point, but requires professionals to interpret it.
It is difficult for non-professionals to understand the roundness analysis report in this data report format

Embodiment Construction

[0012] refer to figure 1 Shown is a hardware implementation architecture diagram of a preferred embodiment of the roundness calculation and display system 20 of the present invention. The system 20 is installed and runs in an application server 2 . The application server 2 has a built-in or external database 1 and is connected to at least one client computer 4 (two are shown in the figure) through a network 3 . The database 1 is used for storing multiple groups of point sets. The network 3 may be an intranet (Intranet), the Internet (Internet) or other types of networks. The client computer 4 can provide an interactive user interface for displaying the process of processing the point set in the database 1 and outputting a graphical roundness analysis report.

[0013] refer to figure 2 Shown is a functional block diagram of the roundness calculation and display system 20 of the present invention. The system 20 mainly includes a color scale setting module 200 , a point set...

Abstract

The invention provides a roundness calculation and display method. The method comprises the following steps: setting a color gradation stripe, wherein different colors in the color gradation stripe represent different error ranges; receiving a converged point set; fitting the point set to form a circle by a least square method, namely a fitting circle; calculating the distance di between each point in the point set and the fitting circle, wherein the distance di is an error value of the point; comparing the error value of each point in the point set with the set color gradation stripe to confirm the color of each point; and drawing and outputting a figure roundness analysis report, wherein the figure roundness analysis report comprises the color gradation stripe, the fitting circle and thepoint set with colors. The invention also provides a roundness calculation and display system. The invention can realize the figure display of a roundness calculation result.

Description

technical field [0001] The invention relates to a roundness analysis system and method, in particular to a roundness calculation and display system and method. Background technique [0002] Roundness is a shape tolerance, indicating the degree of out-of-roundness of a circle, which is very commonly used in the field of precision measurement. [0003] The measurement program in the current image measurement can realize the roundness calculation of the circle. However, the traditional analysis report of the roundness calculation results is in the form of a data report, and its content is relatively simple, which cannot intuitively display the error status of each point, but requires professionals to interpret it. It is difficult for non-professionals to understand the roundness analysis report in this data report format. Contents of the invention [0004] In view of the above, it is necessary to provide a circularity calculation and display system, which can draw points an...
