Measure Height Difference Point to Point

Function

This Step is used to calculate the height difference from the detect point to the base point.

A line segment connecting the two specified points will be automatically drawn, and the variation of heights along the line will be shown in the height view widget.

Hint

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

Sample Application

../../../../../_images/sample_application1.png

Connect Read Point Cloud V2, Orthographic Projection, and Measure Height Difference Point to Point to calculate the height difference from the detect point to the base point.

Connect Steps

  1. Click on Orthographic Projection , go to the Step Input Source Selection panel, and then select Read Point Cloud V2_1_Point Cloud With Normals as Input 1 (Point Cloud With Normals).

  2. Click on Measure Height Difference Point to Point, go to the Step Input Source Selection panel, and then select Orthographic Projection_1_Depth Image as Input 1 (Visualization Background).

Configure parameters

Note

Please prepare the point cloud of the object to be measured in advance.

  • Configure in Read Point Cloud V2

    Click on the Step, and configure the Point Cloud Source and other parameters in the Step Parameters panel.

  • Configure in Measure Height Difference Point to Point

    The baseline point and detect point are located in the upper left corner in the sketchpad area by default. Please drag them onto the point cloud.

Hint

You can set the LSL (lower specification limit) and USL (upper specification limit) in Measurement Output and Result View panels to check whether the measurement conforms to the specification.
