[Ref. Position (3D Edge Position)]

This item can be changed if necessary. The reference measurement is executed at the same time as the measurement region is specified, with the reference position set automatically. This item can be used to change the reference position to any desired position.
For the reference position, see

User's Manual, "Terminology".

In the "Item tab" area, tap [Ref.position].
Set the reference position.
There are two methods to set the reference position: by performing the reference measurement while the image to be measured is displayed, or by specifying the reference coordinates directly.
Measuring the image to set the reference position
While the image to be measured is displayed, tap [Measure ref.].
The measurement coordinates are re-calculated, and the cross-shaped cursor is displayed in the "Reference coordinate" area.
Specifying the reference coordinates directly
Specify values for "Ref. position X", "Ref. position Y", and "Ref. position Z".
In the Reference Coordinate area, tap [...] for each item and specify values for your desired reference coordinates (the coordinates of the reference position).
How to input a value: User's Manual, "Inputting a Value"
Note
- Note the following when the reference coordinates are specified directly:
  - The cross-shaped cursor will not be displayed in the "Reference coordinate" area.
  - Although the X-, Y-, and Z-coordinates shown on the screen are the input values (mm), the X- and Y-coordinates which are referenced as measurement coordinates in result display processing items, etc. are the X- and Y-coordinate values (in pixels) on the Camera 0-side or Camera 2-side. These coordinate values do not change even if the reference coordinate values change.

Note

Since the reference position can be changed, it is useful for measuring distance from a specific position.

Confirm the reference position of the currently displayed image, and then change it to an appropriate position. A positional check can be performed by calculating the difference between the reference position and the measured position using an expression.
After changing the reference position to any desired position, changing the measurement region will automatically change it back to the default position.
