Upgrading mapping using original data

This article details the complete workflow for upgrading mapping using original data in both single-image and multi-image scenarios, including task creation, data upload, mapping operations, and result viewing. It helps users complete map version upgrades while maintaining the original coordinate system.

Upgrading mapping for single-image using original data

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.

Creating single-image lossless update task

Select the single-image task that needs lossless upgrade and click the Lossless point cloud upgrade button.
Fill in the following information in the pop-up window:

Task name: Enter the name for this lossless update task.
Data location: Select Lossless upgrade.
Mapping version: Recommended to use the latest version V9.
Data format: Recommended to use the latest version 3-a.

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 your computer powered on and the network stable. Do not close the browser, refresh the page, or click other menus, otherwise the upload will be interrupted and require re-operation.

Starting 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 Queuing or Generating, as shown below. Please wait patiently for mapping completion.

Mapping generating

Confirming mapping results

After the task enters the mapping process, you can determine whether the mapping task is completed through the Task status. When status displays Task completed or Generation failed, it indicates the mapping task has ended.

Mapping task completed

Successful mapping

When task status shows Task completed, it indicates successful mapping and results are generated. You can further view mapping results to confirm if they meet expected requirements.

Mapping failure

When task status shows Generation failed, it indicates mapping failure. 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.

Upgrading mapping for multi-image using original data

Creating multi-image lossless update task

Select the multi-image task that needs lossless upgrade and click the Lossless point cloud upgrade button.
Enter the task name in the pop-up dialog, select mapping version and data format (recommended to use latest version). After filling, click Confirm add to create the multi-image point cloud lossless update task.

Adding auxiliary mapping

After creating the multi-image lossless update task, you need to add auxiliary mapping tasks for each independent collection area.

Click Multi-image merging management to enter the corresponding management interface.
Click Add auxiliary mapping, enter task name and click Confirm to create a sub-image. Note that each independent collection area requires creating an auxiliary mapping task.

Uploading data

Copy the name of the multi-image task needing lossless upgrade. Under the corresponding task, click the Upload data button.
In the pop-up dialog, select Uploaded data for data location, then click the Select button for collection data.
In the select uploaded data dialog:
- Select corresponding project from "Data belonging project" dropdown
- Paste the multi-image task name needing lossless upgrade in "Data belonging task" dropdown. The system will quickly search for the specified task
- Select data belonging sub-image to view corresponding sub-image data
- Finally click the Confirm button to complete selection
After confirming data selection is correct, click the Confirm upload button.
The task status in the list will update to Upload completed. When all auxiliary mapping tasks have been uploaded, you can start mapping.

Starting multi-image lossless upgrade mapping

The operation flow for multi-image lossless upgrade mapping is consistent with multi-image merging mapping. For specific steps, refer to the Starting multi-image merging mapping section.
