Automated Data Flagging tells you when a capture reconstructed successfully but with a warning. Our goal at Looq is to get you as much usable data as possible, as fast as possible, even when the capture environment isn't ideal. For now it reports one main thing, lost tracking. More types of warnings will be added in the future.

Looq relies on continuous camera tracking to reconstruct a scene in full. That isn't always possible, because the environments our users work in are often difficult. Heavy vegetation, or something blocking the camera, can make tracking fail. Instead of rejecting the capture, Looq splits it into segments at each point where tracking was lost and aligns each segment separately. Automated Data Flagging marks the capture and shows you where those breaks are, so you know which parts to check before you rely on them. Flags appear on their own. There is nothing to run.

Before you start

• Flags appear only on captures that have finished processing.
• A capture with no warnings has no flag.

Why captures get flagged

A capture is flagged when tracking was lost, usually because it entered an unsupported environment such as heavy vegetation, or because the camera was blocked. For more on which environments Looq can't track in, see the unsupported captures article. For how a capture is reconstructed in segments, see the segmented reconstruction article.

What gets flagged

A capture is flagged when either of these warnings applies. A capture can carry both.

Two supporting notes can appear alongside a flag: Tracking started late and Tracking ended early. They mean the model starts after the first frame or ends before the last one. They never flag a capture on their own.

Find flagged captures

In the Captures list, a flagged capture shows a warning triangle at the right of its row. In the table view, the status column reads Flagged.

To see only flagged captures, press the Flagged filter above the list. The list then shows, for example, “5 of 27 captures” and “1 filter active”. Press Clear to see every capture again. The filter stays unavailable until Looq has finished loading the warnings for the site.

The Flagged filter is on: five of the site's 27 captures have a warning triangle.

Investigate a flagged capture

1. Press the warning triangle next to the capture. Looq shows the capture, zooms the map to it and opens the Capture events pane on the right.
2. Read the warnings at the top, then the three tiles: Reconstructed (the percentage of the capture in the model), Tracking breaks (how many times tracking was lost) and Frames in model (frames reconstructed out of frames captured).
3. Step through the breaks with the Break buttons. The heading shows which break you are on, for example Break 1 and “1 of 2”.
4. Select Tracking lost or Tracking recovered to jump between the frame where tracking was lost and the frame where it recovered.
5. Use the play slider under the image to play, step, or drag through the frames around the event. The Camera menu switches between the Front, Right, Top, and Left cameras and All cameras.

The Capture events pane for a capture with both warnings. Break 1 is selected, showing the frame where tracking was lost.

Read the map

When you open a flagged capture, the 2D map colours its track by GNSS quality, so you can see whether a tracking break lines up with weak positioning. A red dashed line marks each tracking break. The points on it are where tracking was lost and where it recovered. Select a point to open that break. The point cloud viewer draws the same break lines in 3D.

The legend at the bottom right explains the colours. The red dashed line is the tracking break.

When you close the pane, the map goes back to the colours it had before.

Watch the full capture video

Press Watch Full Video in the pane to open the Full capture video dialog. It plays a video of the whole capture from all cameras, which helps you see what the drive looked like around the break.

Ask Support about a capture

If you can't tell why a capture was flagged, or you want it looked at, press Contact Support in the pane.

1. The Capture field shows the capture and can't be edited.
2. Under Event (optional), choose a specific event, or “General question about this capture”. The event you were viewing is marked “(current)”.
3. Write your question in Your question. It can be up to 4,000 characters.
4. Press Send. Looq shows “Support request sent”.

The Contact support dialog. Looq attaches the capture's details so Support doesn't need to ask which capture you mean.

Looq creates a support ticket with your name and email, so Support can reply to you directly.

Good to know

• Flags appear after processing finishes. A capture that has just finished can take up to about 30 seconds to show its flag.
• You can't dismiss a flag or add a comment to it. The only action is Contact Support.
• A capture without a flag either had nothing to report or its check was not available. If you expected a flag and don't see one, contact Support.
• The 90% threshold for partial reconstruction is fixed and can't be changed.
