Reviewing Observation Scan Images and Annotations

When the Machine Vision process has finished, you will need to review the analyzed Images together with any detected integrity issues. This can be accomplished either in the Image Gallery under the Observation Scan Main Screen, or using the 3D Observation Module which integrates the Observation Scan results with the 3D Model.   

Opening Images in the Image Gallery

You can view the Images processed by Machine Vision in the Image Gallery. The Image Gallery can be activated from the Observation Scan Main Screen. There are two options: 

• Option 1: Click on the Tag name.

• Option 2: Select multiple Tags and click the Image Gallery button.

• The Image Gallery for the selected Tags will be opened.

To change the size of thumbnails displayed in the image gallery:

• Select the desired thumbnail size (Small, Medium, Large) from the dropdown.

Observation Scan Image Gallery functions

At the top of the Observation Scan Image Gallery you will find a toolbar, containing the following buttons:

In the Image Gallery you can do the following:

• Open an Image in review mode, by clicking on its thumbnail. 

• Filter the Images with various criteria.

• Select multiple Images with the checkboxes on the thumbnails.

• Browse through the Images, by clicking on the left / right arrow buttons on the large image, and by click left / right arrows on the keyboard.

• Opening Images in Review Mode where Images can be Reviewed and Annotations can be Edited.

Filtering Images

You can apply filters to manage which Images are shown in the Image Gallery. 

• Click the Filter button on the right side of the screen to opens the filter dialog.

• Select the desired filters.

The thumbnail list will be automatically updated to reflect the selected filters.

The Observation Scan Image Gallery filters will return all of the resulting Image Segments which match the selected filter criteria.

To filter Images based on Issue Class:

• Click the Filter button.

• Expand Issue Class by clicking +.

• Select one or more Issue Classes to display Images with those Issue Classes.

Searching for Images

To search for a specific image in Observation Scan:

• Copy the Image Path or File Name from Azure Storage.

•  Enter either the Image Name or the Path into the appropriate textbox in the Filter tool.

After you press the Enter key, Images with a matching name will be displayed in Observation Scan.

Annotation Color Codes

Image Annotations are color-coded to help you manage them.

• Machine Vision annotations are colored blue.

• Modified Machine Vision annotations are colored orange.

• Human annotations are colored bright green.

• Machine Vision annotations that are flagged as correct are colored dark green.

Changing Annotation size and location

To edit the size and location of Annotation Boxes:

• Click the desired Annotation Box.

  

• Drag from the corners to resize.

• Drag the Annotation Box to reposition.

A modified Machine Vision Annotation Box will still be considered to be a Machine Vision detection but will be colored orange.

Changing Issue API Class for Annotations

You can change the Issue API Class on existing detections by doing the following:

• Select one or more Annotation Boxes.

• Click the Issue Class button.

• Select an Issue Class.

  Selecting Issue API Class.

Creating new Annotations

You can create a new integrity issue (Observation Item):

• Select a desired Issue Class from the Issue API class dialog.

• Click the Draw New Annotation button on the toolbar.

• Draw the rectangle in the desired position.

Deleting Annotations

To delete detected integrity issues, i.e., Observation items:

• Select one or more detections on the image.

Setting Images to "Reviewed"

When you are satisfied that all of the Image Annotations are correct, the Image status should be set to Reviewed.  To change the Image status:

• Click on Not Reviewed in the upper right corner of the image.

When Image has been marked as Reviewed, all non-modified Machine Vision Annotations will be flagged as correct, and the next Image in the gallery will be automatically loaded. 

Back in the Observation Scan List, you can monitor your progress, i.e., see the number (and %) of MV Annotated Images done and Human Annotated Images done, and how many of them have been marked as Reviewed. The number of Total Human Annotations and Total Machine Annotations are also shown in the grid.
