Creating large-space fusion tasks
This article details the complete operation process for large-space multi-map fusion tasks, including task creation, data preparation, data upload, mapping operations, and result viewing, ensuring users can efficiently complete complex scene mapping requirements.
Large-space multi-map fusion functionality requires business consultation for activation. We will review based on project requirements and environmental space, unlocking fusion mapping permissions after approval. With permissions, you can manually create multi-map fusion tasks in mapping tasks.
Create multi-map fusion task
After creating a project, click Manage to enter the mapping task management interface. With multi-map fusion permissions, click the Multi-map Fusion Task button in the upper right corner. Enter the task name in the dialog box, select the mapping version and data format (recommended to use the latest version), then click Confirm Add to create the multi-map fusion task.

Add sub-maps
After creating the multi-map fusion task, add sub-map tasks for each independent collection area.
Click
Multi-map Fusion Managementto enter the corresponding management interface.

Click
Add Sub-map, enter the task name and clickConfirmto create a sub-map. Note: Each independent collection area requires a separate sub-map task.

Data preparation
Before starting the mapping task, ensure collected spatial data meets requirements and is organized/stored according to specifications. Preparation standards are similar to single-map tasks, differing only in collection methods.
Data collection and export
Use panoramic cameras to collect spatial data. Refer to:
- GoPro max device configuration
- Collection route planning
- Large-space data collection methods
- Collection checklist
- GoPro max data export
Other data specifications
- Data folder naming
- Data storage location
- Data file structure specifications
- Data file naming conventions
Upload data
Upload rules are identical to single-map tasks. Upload data under corresponding tasks. Refer to single-map task data upload.

Start multi-map mapping
After uploading all task data, click Auto-link Mapping or Manual-link Mapping to begin. Please wait patiently as multi-map fusion tasks take longer. Contact business support if prolonged.
Auto-link mapping
- Suitable for most scenarios.
Manual-link mapping
Used when mapping results don't meet expectations.
Steps to manually specify sub-map relationships:
Arrange sub-task blocks according to actual collection area positions

Create connections between sub-tasks
Principle: Add links when sub-task data overlaps.
Steps:- Click one sub-task, then another to create connection.
- Error handling: Click connection line to turn red, then click
Delete Link. - Delete all connections: Click
Clear Relationshipsin top right. - Temporary save: Click top-right
Saveto resume later.

For multi-floor scenarios:
a. CheckEnable Multi-floor Mode.
b. ClickAssign Floorin each sub-map box to add floor information.

Verify all connections and click
Map with Specified Relationshipsto start.
Auxiliary functions
The following functions help manage and operate mapping tasks efficiently:
View uploaded files
Verify file completeness to prevent mapping failures.
Click
Multi-map Fusion Management→View Uploaded Filesto check file lists.

Click specific
LRV Filesto preview video quality.

Upload EIF
EIF data enables remote debugging and simulated positioning in Mega. For collection details, see EIF data collection guide.
Upload steps:
- Click
Multi-map Fusion Management→Upload EIFfor corresponding sub-map.

- Select EIF directory folder →
Confirm Upload.

View uploaded data:
After uploading, click View Uploaded Files to see EIF files. Supports download/delete.

Stop mapping
Click Stop Mapping before completion if incorrect data is uploaded. Confirm in popup.

Delete task
Click Delete Task for failed/unneeded tasks. Confirm with Delete in popup.

Confirm mapping results
Check Task Status to determine completion. Multi-map fusion tasks end when status shows Task Completed, Suboptimal Mapping Result or Generation Failed.

Successful mapping
Status Task Completed or Suboptimal Mapping Result indicates success. Results display in multi-map fusion management interface.
Result explanations:
Task Completed: Mapping finished with successful fusion → single Mega Block.
Suboptimal Mapping Result: Mapping finished but poor fusion → multiple Mega Blocks.

For
Suboptimal Mapping Result, check:- Collection route compliance (reference: collection specifications)
- File upload completeness (reference: preview uploaded files)
- Collection coverage (reference: review collection routes)
- Manual-link accuracy (reference: manual-link mapping)
Correct issues and recreate tasks if found. Contact support if all checks pass.
