Measure Distances Circles to Circles

Function

This Step is used to measure the distances from circles to circles.

Hint

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

Sample Application

../../../../../_images/sample_application5.png

Connect Read Images V2, Measure Circles, and Measure Distances Circles to Circles to measure the distance between the centers of two circles or the nearest distance between two circles.

Connect Steps

  1. Click on Measure Circles (1), 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 Circles (2), 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 Circles to Circles, go to the Step Input Source Selection panel, and then select Measure Circles_1_Circles as Input 2 (Circles) and Measure Circles_2_Circles as Input 3 (Circles).

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 Image 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 Circles (1)

    Click on the Step, and select an ROI in the sketchpad area.
