Data Capture

This chapter covers GNSS settings, project naming and scan settings, scanning, rendering modes, Scan Assist, model viewing, and data export.

GNSS Settings

Tap GO to open GNSS settings.

Note

To skip GNSS, tap "Skip" in the upper-right corner, or turn off GNSS in Settings to skip this screen by default.

GNSS mode

GNSS Mode	Function	How to Use
RTK	Receives correction data through the RTK module for real-time positioning; saved to the project file	Select RTK mode; process with the RTK module in LixelStudio
PPK	Records raw satellite observations through the RTK module; saved to the project file	Select PPK mode; process with the PPK module in LixelStudio

RTK account management

Tap Connect to save frequently used accounts to the device. Manage them from the account list under GNSS Mode.

GNSS settings with a saved account selected — GNSS settings

Note

Custom RTK services must use a standard data format.
After first setup, the device saves your RTK account and stays signed in until you disconnect.
Disconnecting can take 1–2 minutes.
Coordinate system changes take about 5 minutes to apply. Wait 5 minutes before starting work.
The RTK module supports WGS 84, CGCS2000, and ITRF2008. Heights are ellipsoidal.

RTK status indicator

Color	Status
Red	RTK not connected
Blue	RTK connected, not fixed
Green	RTK connected, fixed solution

RTK connection status and satellites

Once connected, a confirmation appears and the "Connect" button changes to "Disconnect". RTK status and satellite count show in real time below Mountpoint. Tap Next.

Project Naming and Scan Settings

Mounting Mode	Function	Description
Handheld	Handheld operation	LixelStudio reads the mounting mode automatically; no need to reselect it during processing

Scan mode

Mode	Function	Supported Rendering Modes
Guided mode	Evaluates scan quality in real time	Scan Assist and scan quality rendering; no true-color rendering
RGB mode	Shows the true-color point cloud in real time	True-color rendering; no Scan Assist or scan quality rendering

Custom naming

Example: Enter "park" as the project name and start scanning. In USB storage mode, the project folder appears as "park_2026-01-15-1622026", where "2026-01-15-1622026" is the scan time.

With no project name, the folder appears as default_2026-01-15-1622026.

Naming Assistant

Naming Assistant builds names in a "Name_Floor_Count" format, for example BlockA_1_1. In USB storage mode, the project folder appears as BlockA_1_1_2026-01-15-1622026.

Tap Done to open the start screen.

Start Scanning

Start the Device

Place the Lixel L3, with the base mount attached, on stable, level ground.
On the start screen, press and hold anywhere to start scanning.
The LiDAR starts spinning, the indicator flashes green rapidly, and a startup tone plays. The device then enters static initialization.
Keep the device still until initialization completes. A tone plays and normal scanning begins.
Slowly lift the scanner, then slowly detach the base mount, and begin scanning.

Scan Route Recommendations

Lighting

Choose even lighting.
Avoid strong contrast between light and shadow.

Field of view

Prefer open routes (such as the middle of a road) for better color coverage and accuracy.

Narrow spaces (such as gaps between buildings or alleys)

Walk slower than normal.
Wait for people and moving objects to clear.
This keeps the point cloud accurate and well colorized.

Notice

Narrow spaces are harder to capture well. Take your time.

Rendering Mode

Tap "Rendering Mode" in the lower-right corner of the screen to switch display modes:

Mode	Description
EL Elevation	Colors points by height to show terrain
RGB True color	Shows true color for easy object identification
QUAL Scan quality	Shows point density in real time to check coverage

Notice

Available modes depend on the scan mode (Guided or RGB). For RGB display, set the scan mode to "RGB mode" on the project start screen.

About scan quality display

Purpose: Checks point cloud density to prevent rework from missed or sparse areas.
Note: Does not indicate scan accuracy or LCC scan quality.

Switch to QUAL regularly while scanning to catch missed areas.

Scan Assist

Purpose

Checks whether point cloud density meets the threshold.
Prevents rework from missed or sparse areas.

Note

Does not indicate scan accuracy or LCC scan quality.

How to Use

After starting a scan, tap "Scan Assist" below the stop button.
The settings screen opens.
Set the step distance for the site.

Notice

Match the step distance to scene complexity for complete coverage.

Stop Scanning

Press and hold the red button at the bottom center of the screen to save data.

Saving runs in two stages: storing the data, then generating a viewable point cloud model.

The point cloud model then opens automatically for on-site checking.

View Model

After scanning, view the point cloud model on the device screen.

Export Scan Data

Steps

Connect to a computer: Power on the device and connect it with a USB-C cable. Tap Confirm on the USB storage mode prompt, or wait for the countdown.
Copy project files: Open the device storage, go to the model folder, and copy the project files to your computer.

Project File Naming

File name format: ProjectName_YYYY-MM-DD-Time. Examples:

ParkingB2F_2025-01-15-162026
default_2025-01-15-143520

Notice

Files are named by scan start time for easy identification.

Project File Structure

Project files:

File	Subfile	Description
xxx.xbin	-	Raw sensor data
map.las	-	Real-time point cloud from the device.
project_data	control_points.csv	Control point information recorded during the scan.
	gnss.csv	GNSS data recorded when using RTK.
	poses.csv	Scan trajectory.
	photo	Camera images taken when control points are added
	model	Model preview files
	thumb.jpg	LixelGO preview image
	preview_photo.jpg	Device preview image
	log	Scan log
external_data	-	Empty when first copied. Holds external files for LixelStudio post-processing, such as the coordinate-transformed gnss.csv.
