Measure Distances Points to Segments

Function

This Step is used to measure the distances from points to line segments.

Hint

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

Attention

This Step does not support custom specified points, the points can only be obtained from Measure Circle or Detect Circle Centers.

Sample Application

Connect Read Images V2, Measure Circle, Measure Longest Line Segment, and Measure Distances Points to Segments to measure the distance from points to line segments.

Connect Steps

  1. Click on Measure Circle , go to the Step Input Source Selection panel, and then select Read Images V2_1_Color Image as Input 1 (Color Image).

  2. Click on Measure Longest Line Segment , go to the Step Input Source Selection panel, and then select Read Images V2_1_Color Image as Input 1 (Color Image).

  3. Click on Measure Distances Points to Segments, go to the Step Input Source Selection panel, and then select Measure Circle_1_Circles as Input 2 (Points) and Measure Longest Line Segment_1_Line Segments as Input 3 (Line Segments).

Configure parameters and read the result

Note

Please prepare color image(s) that contain object(s) to be measured in advance.

  • Configure in Read Images V2

    Click on the Step, and configure the Imgae Source, Image File/Folder Path, and other parameters in the Step Parameters panel. After completeing the configuration, click on Run to run the project.

  • Configure in Measure Circle
