Lossless full update mapping

This article details the complete operation process for lossless full update mapping of single and multi-graphs, including task creation, data upload, mapping operations, and result viewing, helping users complete scene updates while keeping the original coordinate system unchanged.

Single graph lossless update mapping

Log in to EasyAR Development Center, select Mega Block -> Block mapping from the left menu bar, choose the corresponding project address, and click the Manage button to enter the mapping task interface.

Enter project management interface

Create single graph lossless update task and upload data

  1. Select the single graph task that requires lossless update, click the Lossless point cloud upgrade button.
    Click lossless upgrade button

  2. Fill in the following information in the pop-up window:

    Single graph lossless

    • Task name: Enter the name for this lossless full update task.
    • Data preparation: Please refer to regular single graph task data preparation.
    • Data location: Select Upload new data.
    • Collection data: Click Choose, select the main directory folder of the data, then click Upload.
      Upload new data
    • EIF data: Optional, click the Choose button to upload the corresponding EIF data file. Supports supplemental EIF data upload after mapping starts.
    • Upload region: Select the nearest location based on the operator's location.
    • Mapping version: Default uses the latest version V9.
    • Data format: Recommended to use the latest version 3-a.

  3. After confirming all information is correct, click the Confirm upload button to submit the task. The list will display upload progress and status.
    During data upload, keep the computer powered on and network stable. Do not close the browser, refresh the page, or click other menus, otherwise the upload will be interrupted and require restarting.

Start mapping

After upload completes, the task automatically enters Under review, as shown below.

Mapping under review

After approval, the task automatically enters the mapping process, with status showing Queued or Generating, as shown below. Please wait patiently for mapping to complete.

Mapping generating

Confirm mapping results

After the task enters the mapping process, check the Task status to determine if mapping is complete. When status shows Task completed or Generation failed, the mapping task has ended.

Mapping task completed

Mapping success

When task status shows Task completed, mapping succeeded and results are generated. You can now view mapping results to confirm if they meet expectations.
View mapping results:

Mapping failure

When task status shows Generation failed, mapping failed. Recommended troubleshooting steps:

  • View mapping report: View mapping report, find solutions based on report information.
  • Reference troubleshooting: Consult mapping failure troubleshooting guide for common solutions.
  • Contact technical support: If above methods don't resolve the issue, contact EasyAR staff and provide the JobID from the mapping report for quick problem identification.

Multi-graph lossless update mapping

Log in to EasyAR Development Center, select Mega Block -> Block mapping from the left menu bar, choose the corresponding project address, and click the Manage button to enter the mapping task interface.

Enter project management interface

Create multi-graph lossless update task

  1. Select the multi-graph task requiring lossless update, click the Lossless point cloud upgrade button.

    Enter project management interface

  2. In the pop-up dialog, enter the task name, select mapping version and data format (recommend latest version), then click Confirm add to create the multi-graph point cloud lossless update task.

    Enter project management interface

Add sub-mappings

After creating the multi-graph lossless update task, add sub-mapping tasks for each independent collection area.

  1. Click Multi-graph fusion management to enter the corresponding management interface.

    Multi-graph fusion management

  2. Click Add sub-mapping, enter task name and click Confirm to create a sub-graph. Note: Each independent collection area requires a separate sub-mapping task.

    Add sub-mapping

Data preparation

Before uploading data, ensure collected spatial data meets requirements and is organized/stored according to specifications. Below details naming, storage, and structure specifications for data collection devices and files.

Upload data

Upload rules are identical to single graph tasks. Upload data under corresponding tasks. Refer to single graph task data upload for details.

Data upload location explanation: Choose Local new data or Alibaba Cloud link upload method.

Multi-graph lossless upload data

Start multi-graph lossless update mapping

Multi-graph lossless update mapping follows the same workflow as multi-graph fusion mapping. Specific steps refer to starting multi-graph fusion mapping chapter.

Confirm mapping results

After the task enters mapping process, check Task status to determine completion. When multi-graph lossless update task status shows Task completed, Mapping results unsatisfactory or Generation failed, the mapping task has ended.

Mapping task completed

Mapping success

When task status shows Task completed or Mapping results unsatisfactory, mapping succeeded and results are generated. After multi-graph mapping completes, results display in the multi-graph fusion management interface.

Mapping result explanation:

  • Task completed: Mapping completed and fusion succeeded, resulting in a complete Mega Block.

  • Mapping results unsatisfactory: Mapping completed but fusion poor, resulting in multiple Mega Blocks.
    Mapping results unsatisfactory

    When Mapping results unsatisfactory appears, recommend checking:

    • Collection route specifications: Ensure routes meet specifications with sufficient overlap between sub-graphs. (Reference: collection specifications)
    • File upload completeness: Confirm all files uploaded without omission. (Reference: preview uploaded files)
    • Collection area coverage: Verify areas cover all requirements without missed collections. (Reference: review collection routes)
    • Manual association accuracy: If manual association mapping performed, ensure accurate sub-graph relationships. (Reference: manual association mapping)

    If any issues found, correct and recreate tasks. If all checks pass, contact us for assistance.
