7.1 LCC Scan App Deep Dive
The LCC Scan app is the complete field control interface for the PortalCam. Every scanning action, status indicator, and in-field decision point runs through it. Knowing what each element tells you during an active scan changes how quickly you catch problems before they compound.
LCC Scan vs. LixelGO
LCC Scan is the PortalCam's dedicated field control app. It is not interchangeable with LixelGO. If you operate both a PortalCam and a K1 or L2 Pro, you use LCC Scan for the PortalCam and LixelGO for the K1 or L2 Pro. The two apps cannot be swapped or used across device types.
LCC Scan is available on iOS and Android. The Android version is installed via APK from the XGRIDS download link. The iOS version is available through the App Store. Both require Bluetooth, location, and hotspot permissions to be granted before the app can connect to the PortalCam.
Device Controls and LED States
The PortalCam body has two physical buttons: the power button and the device button. Understanding what each button does and what the LED states mean is essential for field operation, especially when the phone connection is unavailable.
LED Indicator Reference
Fast green flash means the device is saving. Do not power off. This is the same critical rule as with the K1 and L2 Pro. When you stop a scan, the fast green flash indicates the project file is being written to internal storage. Powering off during a fast flash corrupts the project file. Wait for it to return to solid green before handling the device or removing the battery.
The Scanning Interface
During an active scan, the LCC Scan app displays the real-time scanning screen. The elements visible on this screen give you constant feedback about scan quality, device health, and coverage progress.
Top Status Bar
The top of the scanning screen shows three pieces of continuous status information: the current storage usage and remaining capacity, the device battery percentage, and the current scanning speed in meters per second. The speed indicator is the primary field tool for maintaining proper technique. Walking speed should remain consistent and within safe limits for the environment you are scanning.
Posture Indicator
The posture indicator icon in the center of the screen changes state when the device tilt exceeds acceptable limits. A posture warning during scanning requires immediate correction. Continued scanning with the device tilted beyond acceptable limits produces point cloud distortion in those sections that cannot be corrected in post-processing.
Point Cloud Preview
The real-time point cloud preview occupies the main area of the scanning screen. It shows the LiDAR data being captured and updates continuously. Use the preview to confirm that the scan is capturing geometry, that coverage is building in the areas you are scanning, and that there are no sudden drops in point density that indicate a tracking issue.
Scan Timer
The timer in the corner shows elapsed scan time. For Map Fusion projects, each segment must stay under 20 minutes. Monitor the timer and plan your segment end points so you stop before reaching the limit. Segments that run over 20 minutes cannot be used in Map Fusion.
Real-Time Alerts
The LCC Scan app displays banner alerts during scanning when specific problems are detected. Each alert requires action in the field, not after the scan is complete.
Action Buttons During Scanning
The LCC Scan interface provides four action buttons during an active scan. These are the in-field tools for all manual interactions with the scan project while it is running.
Control Point
Marks a physical control point location in the scan data. Used for Map Fusion alignment and absolute coordinate anchoring. Requires the device to be placed on a stable surface.
- Requires LCC Scan App 1.2.0_p1 or later
- Requires firmware V3.2.3-20251104 or later
- Tapping adds the point; do not power off within 5 seconds
Measurement Point
Records the coordinates of a specific feature in the scan for reference. Used to label notable objects, infrastructure, or reference locations within the scan data.
- Requires stable positioning at the target location
- Name each point with a consistent labeling convention
- Points appear in the project data after processing
Pause
Temporarily suspends scanning without ending the segment. Used for navigating through crowded areas, waiting for people to clear, or taking a short break.
- Scan data is not lost during pause
- Re-establish a loop closure before resuming to confirm tracking integrity
- Do not pause for extended periods; long pauses may require re-initialization
Stop
Ends the current scan segment. Hold the stop button until the confirmation prompt appears. Confirm, then wait for the fast green flash to complete before touching the device.
- A confirmation dialog appears before the scan actually stops
- Saving begins immediately after confirmation
- Device must not be powered off while fast green LED is active
Left-Hand Mode
LCC Scan supports left-hand operation via a toggle in the app settings under More Settings. This mirrors the button layout for operators who hold the device in their left hand. Check this setting before scanning if the default right-hand layout creates awkward reach during operation.
Dashboard and Project Management
The LCC Scan dashboard shows the project gallery with a card for each completed scan. Each card displays the scan date, duration, and a thumbnail of the scan data. Tapping a card gives you access to the scan details and the View Model option for mobile preview before transferring data to the workstation.
The device status panel, accessible from the dashboard, shows current battery level, firmware version, and connection status. Check firmware version here before starting a project at a new site to confirm the device is running the version required for the features you plan to use. Control point marking for Map Fusion requires firmware V3.2.3-20251104 or later.
