Show the measurement result with classification

Overview

Classify the measurement result into three level, and display it in ImageWindow.

Specification of this example

Behavior

Get the correlation value from [Search] and make classification as below.

Rank	Correlation
A	80-100
B	50- 80
C	0- 50

How to try this example
1.Click the link below, then the folder containing zip file automatically opens.

File

2.Right-click and hold on the zip file, and drop it on working window of FJ system. The images and scene data in zip file are loaded on the program automatically.

3.Re-measure the image. Then System automatically displays the result (ABC) in Image Window.

Explanation

(1)Get judgement result (correlation value) of forward unit via external reference data.
(2)Make classification by threshold value.
(3)Display ranks.
