The thermal reference window can trigger events based on the temperature measured within the specified image areas and compared to the temperature measured in a reference window. Note that you can define different measurement areas for every event profile.

To do so, you can create different temperature events, which react to different areas and reference temperatures.

Important Notes

Edit Measurement Area

The measurement area can be defined as a rectangle or as a polygon.

Rectangle syntax:

image sensor, horizontal position, vertical position, width, height
Example 1. Rectangle Syntax
0,270,190,100,100

Polygon syntax:

image sensor, poly=<hor. coordinate>x<vert. coordinate>{/<hor. coordinate>x<vert. coordinate>}
Example 2. Polygon Syntax
0,poly=270x190/270x289/369x289/369x190

Notes

  • The measurement area refers to the entire image sensor.

  • If the camera image has been mirrored or rotated, the coordinate system of the windows changes accordingly.

Parameter

Description

Image sensor

Selects the image sensor (camera image) to use for this area definition:

  • 0: Right camera image on dual cameras, default setting on mono cameras.

  • 1: Left camera image on dual cameras.

Horizontal position

Number of pixels measured from the left edge of the visible image to the left border of the area (based on a MEGA image 1280x960).

Vertical position

Number of pixels measured from the bottom edge of the visible image to the bottom border of the area (based on a MEGA image 1280x960).

Width

Width of the area in pixels (based on a MEGA image 1280x960).

Height

Height of the area in pixels (based on a MEGA image 1280x960).

Horizontal Coordinate

Number of pixels measured horizontally from the left edge of the visible image to the polygon corner (based on a MEGA image 1280x960).

Vertical Coordinate

Number of pixels measured vertically from the bottom edge of the visible image to the polygon corner (based on a MEGA image 1280x960).

Note

If you would like to define a new measurement area, open the Environment Events dialog and follow the instructions of the Graphically Entering Image Areas help page.

Trigger Mode

Use this parameter to specify when to trigger the event. The following modes are available:

Editing the Reference Area

The measurement area can be defined as a rectangle or as a polygon.

Polygon syntax:

image sensor, poly=<hor. coordinate>x<vert. coordinate>{/<hor. coordinate>x<vert. coordinate>}
Example 4. Polygon Syntax
0,poly=270x190/270x289/369x289/369x190

Note

If you would like to define a new reference area, open the Environment Events dialog and follow the instructions of the Graphically Entering Image Areas help page.

Comparison

Select between triggering the event when it exceeds or when it drops below the specified trigger value measured in the reference window.

Action Type

Define how often the event is to be triggered:

Show Measurement Area

To display the measurement area of a Thermal Reference Window event profile in the live image, select a color from the selection list. In addition, you can set the following options for the measurement area:.

Note

The current temperature in this context is the temperature value determined according to the selected comparison conditions and compared to the specified trigger threshold.

The following options are available for the measurement area and the profile name:


Storing the Configuration

Click on the Set button to activate your settings and to save them until the next reboot of the camera.

Click on the Factory button to load the factory defaults for this dialog (this button may not be present in all dialogs).

Click on the Restore button to undo your most recent changes that have not been stored in the camera permanently.

Click on the Close button to close the dialog. While closing the dialog, the system checks the entire configuration for changes. If changes are detected, you will be asked if you would like to store the entire configuration permanently.
