Create ultra-wide-range fusion tasks
This article details the complete operational process for ultra-wide-range multi-image fusion tasks, including task creation, data preparation, data upload, mapping operations, and result viewing, ensuring users can efficiently complete mapping requirements for complex scenarios.
The ultra-wide-range multi-image fusion feature requires consultation with business for activation. We will review based on project requirements and environmental space, and unlock the fusion mapping permission upon approval. After obtaining permission, you can manually create multi-image fusion tasks in the mapping tasks.
Create a multi-map fusion task
After creating a project, click Manage to enter the mapping task management interface. After obtaining multi-map fusion mapping permissions, click the Multi-map fusion task button in the upper right corner. In the pop-up dialog, enter the task name, select the mapping version and data format (it is recommended to use the latest version). After filling in the information, click Confirm addition to create a multi-map fusion task.

Add sub-mapping
After creating a multi-map fusion task, you need to add a sub-mapping task for each independently captured area.
Click
Multi-map fusion managementto enter the corresponding multi-map fusion management interface.

Click
Add sub-mapping, enter the task name, and clickConfirmto create a sub-map. Note that each independently captured area requires the creation of a sub-mapping task.

Data preparation
Before starting the mapping task, ensure that the collected spatial data meets the requirements and is organized and stored according to the specifications. The data preparation standards are essentially the same as for single-map mapping tasks, with the only difference being in the collection method.
Data acquisition and export
Use a panoramic camera to collect spatial data. For related equipment configuration and key collection points, please refer to:
- GoPro max device configuration
- Collection route planning
- Large space data collection method
- 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
The rules for uploading data are the same as for single-image tasks. Please upload data under the corresponding task. For details on uploading data, refer to Single-image task upload data.

Start multi-image mapping
After all task data is uploaded, click auto-associate mapping or manual-associate mapping to start mapping. Please be patient as multi-image fusion tasks take a long time to complete. If it is not completed for an extended period, please contact the business team.
Automatic association mapping
- Suitable for most scenarios.
Manually associate mapping
Applicable when the mapping results do not meet expectations.
Steps to manually specify multi-map collection relationships:
Arrange the sub-task blocks according to the relative positional relationships of the actual collection area.

Create connection relationships between sub-tasks
Principle: Connections should be added when the collected data of sub-tasks have overlapping parts.
Steps:- Click on one sub-task, then click on another sub-task that needs to be connected to create a connection.
- Handling misoperations: Click on the connection line to turn it red, then click the
Delete connectionbutton to remove the current line. - Delete all connections: Click the
Clear relationshipsbutton in the upper-right corner. - Temporary save: If you need to review the uploaded data, click
Savein the upper-right corner, and you can continue the operation next time.
If there is a cross-floor collection scenario, enable the multi-floor mode to assign floor information to sub-maps:
a. CheckEnable multi-floor mode.
b. ClickAssign floorin each sub-map box to add floor information for the current sub-map.
After checking and confirming that all connection relationships between sub-tasks are correct, click the
Use specified relationships for mappingbutton in the lower-right corner to start mapping.
Accessibility
The following features can help you better manage and operate mapping tasks, improving work efficiency:
View uploaded files
Used to check if the uploaded mapping files are complete, avoiding mapping failures due to missing files.
Click the
Multi-map fusion managementbutton in the operation bar to enter the corresponding multi-map fusion management interface. Click theView uploaded filesbutton to check the list of uploaded files for the corresponding auxiliary mapping in the pop-up window, confirming whether the files have been completely uploaded.
Click on a specific
LRV fileto preview the video content online, ensuring the collected data meets quality requirements.
Upload EIF
EIF data is specialized test data in Mega for remote debugging and simulation positioning, used for remote verification of Mega effects and supporting simulated positioning during remote development. It must be collected using specified tools. For detailed collection methods, please refer to the EIF Data Collection Guide.
Steps to upload EIF:
- Click the
Multi-image fusion managementbutton in the operation bar to enter the corresponding multi-image fusion management interface. Click theUpload EIFbutton in the relevant sub-mapping operation bar.

- Select the EIF data directory folder and click the
Confirm uploadbutton.

View uploaded data:
After uploading, you can click the View uploaded files button to check the uploaded EIF files in the pop-up window. The files support Download and Delete operations.

Stop mapping
Before the multi-map fusion mapping task is completed, if incorrect data is uploaded or the trajectory map data does not match the actual situation, you can click the Stop mapping button. In the secondary confirmation pop-up window, click Confirm to stop the mapping.

Delete task
If the current mapping task fails to generate or is no longer needed, you can click the Delete task button to delete the task. Click Delete in the secondary confirmation pop-up to complete the deletion.

Confirm the mapping result
After the task enters the mapping process, you can determine whether the mapping task is completed through the task status. When the status of the multi-map fusion task shows task completed, mapping result not ideal, or generation failed, it means the mapping task has ended.

Mapping successful
When the task status shows Task completed or Mapping result not ideal, it indicates that the mapping is successful, and the mapping result has been generated. After multi-map mapping is completed, the results will be displayed in the multi-map fusion management interface.
Mapping result description:
Task completed: Mapping is completed and fusion is successful, resulting in a complete Mega Block.
Mapping result not ideal: Mapping is completed but fusion is poor, resulting in multiple Mega Blocks.

When the status
Mapping result not idealappears, it is recommended to perform the following checks and verifications:- Acquisition route compliance: Ensure the acquisition route complies with the specifications and that there is sufficient overlap between different submaps. (Reference: Acquisition specifications)
- File upload completeness: Ensure all files have been uploaded without omission. (Reference: Preview uploaded files)
- Acquisition area coverage: Ensure the acquisition area covers all requirements without missed areas. (Reference: Review acquisition route)
- Manual association accuracy: If manual association mapping was performed, ensure the submap relationships are specified accurately. (Reference: Manual association mapping)
If any of the above issues are found, you can correct them and recreate the task. If all checks are confirmed correct, please contact us for assistance.

Mapping failed
When the task status shows Generation failed, it means the mapping has failed. It is recommended to troubleshoot the issue in the following ways:
- Check the mapping report: View the mapping report and find solutions based on the report information.
- Refer to troubleshooting: Check the Mapping failure troubleshooting guide for solutions to common problems.
- Contact technical support: If none of the above methods resolve the issue, contact EasyAR staff and provide the
JobIDfrom the mapping report for quick problem identification.
