Create a Super-Large-Scale Fusion Task

This article details the complete operation process for a super-large-scale multi-map fusion task, including task creation, data preparation, data upload, mapping operation, and result viewing, ensuring that users can efficiently meet the mapping requirements for complex scenarios.

The super-large-scale multi-map fusion function requires consultation with the business team for activation. We will conduct a review based on the project requirements and environmental space. Upon successful review, the fusion mapping permission will be unlocked. After obtaining the permission, you can manually create a multi-map fusion task in the mapping task section.

Create a Multi-Map Fusion Task

After completing Create a Project, follow these steps to create a multi-map fusion task:

  1. Click Manage to enter the mapping task management interface.
  2. Click the Panoramic Camera Acquisition Task button in the top right corner.
  3. Fill in the task information in the pop-up dialog box:
    • Task Name: Enter a custom task name.
    • Mapping Type: Select Multi-Map Fusion (requires the permission for multi-map fusion mapping).
    • Mapping Version and Data Format: It is recommended to use the latest version.
  4. Click Confirm and Add to complete the creation.

Note

The super-large-scale multi-map fusion function requires contacting the business team to activate the permission. Only after successful review can you create a multi-map fusion task in the mapping task section.

Add Subordinate Mapping Tasks

After the multi-map fusion task is created, you need to add subordinate mapping tasks for each independent acquisition area.

  1. Click Multi-Map Fusion Management to enter the corresponding multi-map fusion management interface. Multi-Map Fusion Task Management
  2. Click Add Subordinate Mapping, enter the task name, and click Confirm to create a sub-map. Note that each independent acquisition area requires the creation of a subordinate mapping task. Create a Sub-Map

Data Preparation

Before starting the mapping task, you need to ensure that the collected spatial data meets the requirements and is organized and stored according to the specifications. The data preparation specifications are basically the same as those for single-map mapping tasks, with only differences in the acquisition method.

Data Acquisition and Export

Use a panoramic camera to collect spatial data. For relevant device configurations and acquisition key points, please refer to:

Other Data Specifications

Upload Data

The rules for uploading data are the same as those for single-map tasks. Please upload the data under the corresponding task. For details about data upload, please refer to Upload Data for Single-Map Tasks.

Upload Data for Multi-Maps

Start Multi-Map Mapping

After all task data has been uploaded, click Auto-Associate Mapping or Manual-Associate Mapping to start mapping. Please be patient at this time as the mapping time for a multi-map fusion task is relatively long. If the task is not completed after a long time, please contact the business team.

Auto-Associate Mapping

  • Suitable for most scenarios.

Manual-Associate Mapping

  • Suitable for cases where the mapping results do not meet expectations.
  • Steps for manually specifying the multi-map acquisition relationship:
    1. Arrange the sub-task blocks according to the relative position relationship of the actual acquisition areas. Manually Specify the Multi-Map Acquisition Relationship
    2. Create connection relationships between sub-tasks. Principle: Add a connection line when the acquisition data of sub-tasks have overlapping parts. Operation steps:
      • Click one sub-task and then click another sub-task that needs to be connected to create a connection.
      • Handling of misoperations: Click the connection line to make it turn red, and then click the Delete Connection button to delete the current connection line.
      • Delete all connections: Click the Clear Relationship button in the top right corner.
      • Temporary save: If you need to view the uploaded data, click Save in the top right corner, and you can continue the operation next time. Manually Specify the Multi-Map Acquisition Relationship
    3. If there is a cross-floor acquisition scenario, enable the multi-floor mode to assign floor information to sub-maps: a. Check the Enable Multi-Floor Mode option. b. Click Specify Floor in each sub-map box to add floor information to the current sub-map. Manually Specify the Multi-Map Acquisition Relationship
    4. After checking and confirming that all connection relationships between sub-tasks are correct, click the Map with Specified Relationships button in the bottom right corner to start mapping.

Auxiliary Functions

The following functions can help you better manage and operate mapping tasks and improve work efficiency:

View Uploaded Files

Used to check whether the uploaded mapping files are complete and avoid mapping failures caused by missing files.

  1. Click the Multi-Map Fusion Management button in the operation bar to enter the corresponding multi-map fusion management interface. Click the View Uploaded Files button and view the list of uploaded files for the corresponding subordinate mapping in the pop-up window to confirm whether the files have been uploaded completely. View Uploaded Files
  2. China Region 1: You can click on a specific LRV file to preview the video online and check whether the quality of the collected data meets the requirements. View Uploaded Files

Stop Mapping

Before the multi-map fusion mapping task is completed, if you find that the wrong data has been uploaded or the trajectory map data does not match the actual situation, you can click the Stop Mapping button and click Confirm in the secondary confirmation pop-up window to stop mapping.

Stop Mapping

Delete a 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 window to complete the deletion operation.

Delete a Task

Confirm Mapping Results

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 Results Are Not Ideal, or Generation Failed, it means that the mapping task has ended.

Mapping Task Completed

Mapping Succeeded

When the task status shows Task Completed or Mapping Results Are Not Ideal, it means that the mapping is successful and the mapping results have been generated. After multi-map mapping is completed, the results will be displayed in the multi-map fusion management interface.

Explanation of mapping results:

  • Task Completed: Mapping is completed and fusion is successful. The mapping result is a complete Mega Block.

  • Mapping Results Are Not Ideal: Mapping is completed but fusion is poor. The mapping result consists of multiple Mega Blocks. Mapping Results Are Not Ideal

    When the status Mapping Results Are Not Ideal appears, it is recommended to conduct the following checks and verifications:

    • Acquisition route specification: Ensure that the acquisition route complies with the specifications and that different sub-maps meet the overlap requirements. (Reference: Acquisition Specifications)
    • File upload completeness: Ensure that all files have been uploaded without omission. (Reference: Preview Uploaded Files)
    • Acquisition area coverage: Ensure that the acquisition area covers all requirements without missing any areas. (Reference: Review the Acquisition Route)
    • Accuracy of manual association: If manual association mapping has been performed, ensure that the sub-map relationships are specified accurately. (Reference: Manual-Associate Mapping)

    If any of the above problems are found, you can correct them and recreate the task. If all the above checks are confirmed to be correct, please contact us for assistance.

Mapping Failed

When the task status shows Generation Failed, it means that the mapping has failed. It is recommended to troubleshoot the problem in the following ways:

  • View the mapping report: View the Mapping Report and find solutions based on the report information.
  • Refer to troubleshooting: Consult the Troubleshooting Guide for Mapping Failures to obtain solutions to common problems.
  • Contact technical support: If the above methods do not solve the problem, please contact EasyAR staff and provide the JobID in the mapping report to quickly locate the problem.
