Mobile Viewer and Field QC
A gap found in the viewer while the scanner is still in your hands costs a few minutes to fix. The same gap found back at the office means a return visit.
Opening the Viewer
After you stop a scan, the project appears as a card in the LCC Scan gallery showing the date, duration, and distance covered. Tap the card, then tap View Model to open the 3D viewer. The viewer reads directly from device storage and needs no network connection, so it works on a job site with no signal.
You do not need to transfer files or run any processing first. This is the on-site review step, and it belongs before you pack up, not after.
The viewer shows raw scan data, not the finished model. Some imperfections here improve after LCC Studio processing. Coverage gaps and large tracking drift do not. Those are field problems, and the field is the only place to fix them.
The Model Quality Indicator
LCC Scan analyzes model quality automatically after every scan. No action is needed to run it. The result is a three-band rating across the model.
Red is a field decision, not an office decision. Poor source data does not improve in processing. Work out why the area rated red, correct it, and rescan while you are standing there. Returning to a site to recapture one room costs more than the extra ten minutes.
Diagnosing a Yellow or Red Area
- Did you walk it too fast, or only once? Slow to 0.5 m/s (1.6 ft/s) and add a return pass in the opposite direction.
- Did you capture it from only one height? Add a low pass and an overhead pass. Single-height coverage is the most common cause.
- Were you too far from the detail? Signage, instrument panels, and recessed areas need the front camera brought close, down to about 1.6 ft (0.5 m), and moved slowly across them.
- Were you too close, or was the surface reflective? Stay about an arm's length from surfaces generally, and back off to about 3.3 ft (1 m) from highly reflective ones. Add passes from additional angles rather than repeating the same approach.
- Did the front camera ever point at the geometry? In narrow corridors and deep recesses the fisheye cameras may be all that saw the surface. Turn the front camera toward it and pass again.
- Was there movement in frame? Screens, foliage, traffic, and people passing through change the scene between frames. Rescan when the area is static.
Viewer Tools
The toolbar gives you five tools. Each answers a different field question.
Elevation mode is the single fastest QC check. A space that needed multi-height coverage should show a gradient from floor to ceiling. If it renders as one flat color, you captured it from a single elevation and it will read thin in the finished model.
Start every review zoomed out to the full extent. That shows you total coverage and the shape of the walked route in one look. Then zoom into anything that looks thin, fragmented, or discontinuous.
Before You Leave the Site
Run this on every segment. Once the gear is packed and you have driven away, every item on this list becomes a return trip.
- Every segment saved cleanly. Each one should have finished its fast green flash and returned to solid green before you powered off. Confirm each project card is in the gallery with a plausible duration.
- No red areas anywhere the deliverable depends on. Open the quality rating for each segment and review the whole model, not only the parts you remember struggling with.
- Multi-height coverage confirmed in elevation mode. Spaces that needed vertical coverage show a floor-to-ceiling gradient. Flat single-color areas do not.
- Interior coverage confirmed with crop. Cut the roof and look down. Missed rooms and unscanned corners are obvious from above and invisible from inside.
- Trajectory is continuous. Turn on the scan path and trace it. Sudden jumps or position breaks indicate a tracking loss, and the affected area needs rescanning.
- Origin view is clean. Jump to the origin point. That frame is what the client sees first when the model opens.
- Control points present and photographed. If the project uses control points, confirm each appears in the point list in LCC Scan and that you have a phone photo of each physical location.
- Battery planned for what comes next. If a firmware update is due before the next session, the device needs to be above 50 percent when it runs.
