This Step is used to calculate the flatness error of the planar point cloud.

  • Degree of flatness is a critical indicator to maintain quality control throughout the manufacturing process. The surfaces of products are usually required to achieve a desired degree of flatness.

  • Flatness error describes the deviation of a measured plane surface from the theoretical plane surface which has the desired degree of flatness.

Before using this Step, please refer to Getting Started with Measurement Mode to learn about basics of Measurement Mode.

Sample Application

calc flatness error application sample

Connect Steps

Click Calc Flatness Error, go to the Step Input Source Selection panel, and then select Read Point Cloud V2_1_Point Cloud With Normals as Input 1 (Planar Point Cloud).

Configure parameters

Configure in Read Point Cloud V2

Click the Step and configure the Point Cloud Source and other parameters in the Step Parameters panel. After configuration, click Run to run the project.

The point cloud used in this sample application is shown below.
