Manual reference image comparison
To create reference camera images and compare
camera images, the user must have the rights to see live images in surveillance
mode (see Administrative
rights and user rights).
The manual reference image comparison helps detect changes in the camera
orientation.
Mobotix cameras are only supported for Motion
JPEG. Reference Image comparison does not work on images from fish-eye cameras.
- Select a camera from
the list and click Create reference image.
The current camera image will be used as reference image. The current
view displays the actual live image of the camera.
- To delete a reference
image, select the camera from the list and click Delete
reference image.
- Select the camerae
and check both images for changes.
- If changes are detected,
click the red con (2) to mark the change as not identical.
- If the images are identical,
click the green icon (4) to mark the image as identical.
- If the changes are
difficult to see, select Show differences
only. The changes detected by the image processing software will
be displayed as red areas in the current view. If no changes are detected,
the current view turns black.
- Deselect Show
differences only to return to the actual camera image.
- Select Activate
computerized support to display a threshold scale. Move the pointer
on the scale to change the threshold values. This changes the threshold
values of the current image and helps discern possible changes in the
image.
- Deselect Keep
aspect ratio to display both images filling the frame. Depending
on the camera image, this setting may distort the image's aspect ratio.
- To print the images,
click the printer icon (3).
