Scanning Workflow

This chapter covers the full capture workflow from starting a scan to exporting data, including scan mode settings, starting a scan, rendering modes, the Scan Assist System, stopping a scan, viewing models, data export, and the project file structure.

Enter the Capture Screen

Tap GO to enter the standby-for-scanning screen.

The device is time-calibrated at the factory, but long storage may cause the time to drift. LixelGO enables automatic synchronization by default, syncing the phone's time to the device. You can also set the device time manually in LixelGO; set the device time and time zone to match your actual location to keep the data records accurate.

Scan Mode Settings

Tap the red Record button on the right side of the screen. The real-time algorithm adaptively maps the scene. Select the following settings based on your situation.

Mount Type

Mode	Function	Description
Handheld	Capture in handheld mode	LixelStudio automatically reads the mount type, so no manual selection is needed during project processing

GNSS Mode

Mode	Function	Description
RTK	Uses the RTK module's RTK function to receive differential data for real-time positioning and records it in the project file	Select RTK mode on the startup page; use the RTK module for project processing in LixelStudio
PPK	Uses the RTK module's PPK function to receive raw satellite data and records it in the project file	Select PPK mode on the startup page; use the PPK module for project processing in LixelStudio

Scan Mode

Mode	Function	Supported Rendering Modes
Guided Mode	Evaluates scan quality in real time to help assess coverage	Supports Scan Assist System and Scan Quality rendering; does not support true-color point cloud rendering
RGB Mode	View the real-time true-color point cloud	Supports true-color rendering; does not support Scan Assist System or Scan Quality rendering

Tip

RGB Mode has about a 10-second processing delay for intelligent analysis and color optimization.

Project Naming

When you start a scan, the startup page shows a project name input field that supports multiple languages.

If you enter "Parking Lot B2F" and start scanning, then enable USB mode after the scan, the project folder is named Parking_Lot_B2F_2025-01-15-1622026, with the scan time as the suffix.
If no project name is entered, the folder is named default_2025-01-15-1622026.

Start Scanning

Static Initialization (Required)

After selecting the scan mode, the device automatically starts the LiDAR:

Watch the indicator light: fast-flashing green means the LiDAR has started; the app prompts "Static initialization started".
Stay still for 15 seconds: do not move the device; keep it stable. The screen shows a countdown; wait for the pop-up "Static initialization complete".
Start scanning: close the pop-up, pick up the device, and start scanning along the planned route.

Note

Do not move the device during static initialization; keep it stable.

Handheld Posture Suggestions

Goal: reduce how much of the operator appears in the camera's field of view to improve colorization.
Recommended: hold the device extended in front of your chest.
Avoid: keeping the device close against your body.

Scan Route Suggestions

Lighting

Choose an environment with suitable lighting.
Avoid strong light/dark contrast.

Field of view

Prefer routes with a wide field of view (such as the middle of a road) to improve color point cloud coverage and colorization accuracy.

Special case: narrow-space scanning (gaps between buildings, alleys, etc.)

Slow down, moving more slowly than normal walking.
Scan when there are no people or moving objects nearby.
Ensure accurate point cloud data and good colorization.

Tip

Narrow spaces require higher scan quality; capture patiently and do not rush.

Rendering Mode

Tap the Rendering Mode button on the left side of the screen to choose a display option:

Mode	Description
`EL` Elevation	Colors the point cloud by height, making terrain relief easy to see
`RGB` True color	Displays the point cloud in true color, making objects easy to identify
`QUAL` Scan quality	Displays point cloud density in real time to help assess coverage

Tip

The available modes depend on the selected scan mode (Guided Mode / RGB Mode). RGB true-color display requires switching the scan mode to "RGB Mode" on the project startup page.

About Scan Quality display

Purpose: check whether point cloud density is sufficient, avoiding missed areas or rework from sparse coverage.
Note: it does not represent scan accuracy, nor does it reflect LCC scan quality.

We recommend switching to QUAL mode periodically during scanning to check coverage and ensure no areas are missed.

Scan Assist System

Purpose

Check whether point cloud density is sufficient.
Avoid missed areas or rework from sparse coverage.

Note

It does not represent scan accuracy, nor does it reflect LCC scan quality.

How to use

After starting a scan, tap Scan Assist System below the stop button.
The system starts and enters the settings screen.
Adjust the step distance based on your situation.

Tip

Set the step distance according to the complexity of the scene to ensure complete point cloud coverage.

Scan Assist System entry: below the stop button

Stop Scanning

Tap the red End Recording button on the right side of the screen.
Confirm to stop scanning in the pop-up.
Watch the indicator light:
- Fast-flashing green: data is being saved.
- Solid green: scanning is complete and data is saved.
When done, you can power off the device or start another scan.

Note

Wait until the indicator light turns solid green before doing anything else, to ensure the data is fully saved.

View Model

After scanning, you can view model information, take measurements, and share offline through LixelGO.

View model information

Measurement

In model view, you can perform distance (line) and area measurements.

Offline Sharing

The LixelGO Offline Preview module lets you quickly share models. The share format is .las.

Downloading Scan Data

Steps

Enable USB mode: after powering on, set the device to USB mode in LixelGO.
Connect to a computer: use a Type-C cable to connect the device to the computer.
Copy project files: open the device's USB directory, go to the model folder, select the corresponding project file, and copy it to a suitable directory on the computer.

Project file naming rule

The file name format is ProjectName_year-month-day-time, for example:

Parking_Lot_B2F_2025-01-15-162026
default_2025-01-15-143520

Tip

The file name automatically uses the scan start time, making it easy to identify and manage.

Data Project File Structure

The project file structure is as follows:

File / Directory	Subfile	Description
`xxx.xbin`	—	Raw sensor data recorded by the device
`map.las`	—	Point cloud output by the device in real time
`project_data`	`control_points.csv`	Control point information recorded when adding control points in LixelGO
	`gnss.csv`	GNSS information recorded when using RTK
	`poses.csv`	Trajectory file recorded during scanning
	`project.json`	Device attributes and related information
	`model`	In-app model preview file
	`photo`	Camera image captured when adding a control point
	`preview_photo.jpg`	Project preview image
	`log`	Log recorded during scanning
`external_data`	—	Empty initially; used to store external data required for LixelStudio post-processing

Note

The directly output real-time point cloud is downsampled. If you need the complete point cloud, use LixelStudio for post-processing.
