14.2.2 Changing object parameters locally

General

When you change object parameters, all object parameters for the whole image are

changed.

However, in some situations you only want to change an object parameter for one

measurement tool only. The reason for this may be that the measurement tool is in

front of a significantly more reflective surface than other surfaces in the image, or

over an object that is further away than the rest of the objects in the image, and so

on.

Procedure

Follow this procedure:

Place at least one measurement tool in the image.1

Right-click the tool and select Parameters. This will display the following

dialog box.

T638028;a3

Select Use local parameters.3

Do one of the following:

■

Let the program calculate the emissivity. This requires knowledge of the

temperature of the object in question.

■

Enter a known value for the reflected apparent temperature.

■

Enter a known value for the distance to the object.

NOTE

You can also change an object parameter locally by right-clicking the measurement

result in the results pane.

■

Using the emissivity calculator requires that Data output is set to Kelvin, Celsius

or Fahrenheit under Options.
