LCC Scan App Deep Dive
The complete field control interface for the PortalCam. Every scanning action, status indicator, and in-field decision point runs through it.
LCC Scan vs. LixelGO
LCC Scan is the PortalCam's dedicated field control app. It is not interchangeable with LixelGO. If you run both a PortalCam and an L2 Pro or K2, you use LCC Scan for the PortalCam and LixelGO for the others. The apps cannot be swapped across device types.
LCC Scan is available on iOS and Android. On Android, install it from the XGRIDS download link as an APK. On iOS, download it from the App Store. Grant Location, Bluetooth, and Local Network permissions before attempting to connect, and keep the phone close to the PortalCam while it pairs.
Device Controls and LED States
The PortalCam body carries two buttons: the power button on the battery and the device button on the body. Both work without a phone connection, which matters when LCC Scan drops mid-job.
Startup and Save Timing
- 25 seconds to start up. Keep the device on the tripod, stationary and level, for the whole sequence. Movement or an uneven surface during startup causes calibration errors that distort the scan or fail it outright.
- About 6 seconds to begin scanning after you press record. Wait for the slow green flash before lifting the device.
- Fast green flash means saving. Do not power off. When you stop a scan the project file writes to internal storage immediately. Powering off or pulling the battery during a fast flash corrupts the file and the data is not recoverable. Larger scans flash for several minutes.
LED Reference
Audible Alerts
The PortalCam sounds an alert at startup, at shutdown, when the battery drops below 20 percent, and again below 10 percent. These are the primary low-battery warning when the phone is mounted and the screen is not in view. Below 10 percent during recording the device force-stops and saves automatically. Below 5 percent it shuts down.
The device enters low-power mode after 5 minutes idle. With no scan started within 5 minutes of power-on, or 5 minutes of inactivity in standby after a scan, power draw falls to roughly one third. The LiDAR stops in this state, though data can still be copied off the device.
The Scanning Interface
Scan Mode Selection
Select the mode before starting. It tunes camera exposure and image processing for the lighting, and it cannot be changed once the scan is running. The wrong mode degrades texture quality in the finished model.
Choose NIGHT when the route crosses a lighting boundary. A lobby with large windows opening into a dark interior corridor is a NIGHT scene, not an INDOOR one. NIGHT handles the wider dynamic range, and the quality it costs you in the well-lit stretch is smaller than the quality INDOOR costs you in the dark stretch.
Top Status Bar
Three values run continuously: storage used against the 512 GB internal capacity, battery percentage, and current speed. Speed is the field tool that matters most. Stay at or under 1 m/s (3.3 ft/s), and drop to 0.5 m/s (1.6 ft/s) or less indoors, in hallways, in dim areas, through doorways, and around corners.
Posture Indicator
The posture icon changes state when device tilt passes 60 degrees from vertical in any direction. Keep the PortalCam between negative 60 and positive 60 degrees, and never point it straight up or straight down. A posture warning needs correction immediately. Data captured beyond the tilt limit is distorted in those sections and cannot be repaired in processing.
Point Cloud Preview
The live preview fills the main area of the screen and updates continuously. Use it to confirm geometry is building where you are walking and to catch sudden drops in point density, which signal a tracking problem while you can still do something about it.
Scan Timer
Watch the timer against two different ceilings. Map Fusion accepts up to 10 segments, each up to 35 minutes, with 200 minutes combined. Because ten segments at 35 minutes exceeds 200, the combined cap is what binds on a large job.
In practice your workstation binds well before any of those. Reconstruction memory use climbs at roughly 2 GB per minute of scan, which makes about 20 minutes the reliable working length on a typical machine and about 30 minutes the ceiling on 128 GB of RAM. Plan against your hardware first and treat 35 minutes as the outer boundary, not the target.
Real-Time Alerts
LCC Scan raises banner alerts during capture for initialization failure, capture anomalies, low battery or memory overflow, and posture or speed violations. Each one requires action in the field. None of them are recoverable after the scan ends.
In-Scan Actions
Two actions are available while a scan is running: adding a point, and stopping. There is no pause function on the PortalCam. A scan runs from start to stop.
Add Point
Places a marker in the scan data at your current location. The dialog asks for a type and a name. The type determines what the marker does at reconstruction, and the name is how the software matches the same physical point across segments. Names are case-sensitive.
- Map Fusion: anchors segments to each other for combined reconstruction
- Aerial-Ground Map Fusion: ties ground segments to drone imagery at takeoff locations
- HD Enhancement: anchors supplementary high-resolution photography to a scene area
- POI: a reference label only, with no alignment function
Requires a current LCC Scan app and current device firmware. After tapping Add, do not power off for 5 seconds. Full placement procedure is in 7.2.
Stop
Ends the segment. Hold the stop button until the confirmation prompt appears, confirm, then wait for the fast green flash to finish before handling the device.
- A confirmation dialog appears before the scan actually stops
- Saving begins immediately on confirmation
- Never power off or remove the battery while the fast green LED is active
Left-Hand Mode
LCC Scan mirrors the control layout for left-handed operation. The toggle is under More Settings. Check it before scanning if the default layout makes the controls awkward to reach.
Dashboard, Settings, and Data Transfer
The dashboard shows a card for each completed scan with its date, duration, and a thumbnail. Tapping a card opens the scan details and the View Model option for mobile preview before you transfer anything to the workstation.
The device settings panel gives you firmware version, storage management and formatting, USB mode, device time and timezone, and the utilities menu where marker types are configured. App settings hold error logs for support, device region, cache clearing, and cable mode.
Verify firmware and app versions before you travel, not after you arrive. A firmware update needs a stable connection and at least 50 percent battery, and control point marking will not function correctly on an outdated build. A site visit is the wrong time to discover this.
Transferring Data
- From standby with the solid green LED, connect the device to the computer with the included USB 3.0 cable.
- The device enters USB mode automatically after about 5 seconds, indicated by a solid blue LED. If the LED stays green, enable USB mode manually from LCC Scan. Automatic entry works with computers only, not phones or tablets.
- The computer detects the PortalCam as an external drive. Open the
modelfolder to reach the project files. - Use only the included USB 3.0 cable. Other cables cost transfer speed and reliability.
- Disconnect when finished. The device returns to standby. USB mode disables itself on restart, and if you enable it while the device is running you must exit it manually before you can scan again.
