Lossless Full Update Mapping

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

Lossless Update Mapping for Single Maps

Log in to the EasyAR Development Center. Select Mega Block -> Block Mapping from the left sidebar menu. Choose the corresponding project address and click the Manage button to enter the mapping task interface.

Enter the project management interface

Create a Single Map Lossless Update Task and Upload Data

  1. Select the single map task that needs lossless update and click the Lossless Point Cloud Upgrade button. Click the lossless upgrade button

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

    Single map lossless

    • Task Name: Enter the name of this lossless full update task.

    • Data Preparation: Refer to Data Preparation for Regular Single Map Tasks.

    • Data Location: Select Upload New Data.

    • Collect Data: Click Select, choose the main directory folder of the data, and then click Upload. Upload new data

    • Mapping Version: The latest version V9 is used by default.

    • Data Format: It is recommended to use the latest version 3-a.

  3. After confirming that all information is correct, click the Confirm Upload button to submit the task. The upload progress and status will be displayed in the list. During the data upload process, keep your computer powered on and the network connected. Do not close the browser, refresh the page, or click other menus, otherwise the upload will be interrupted and you need to start over.

Start Mapping

After the upload is completed, the task will automatically enter the Under Review status, as shown in the following figure.

Mapping under review

If the review is passed, the task will automatically enter the mapping process, and the status will be displayed as In Queue or Generating, as shown in the following figure. Please wait patiently for the mapping to complete.

Confirm the Mapping Results

After the task enters the mapping process, you can judge whether the mapping task is completed through the Task Status. When the status is displayed as Task Completed or Generation Failed, it means that the mapping task has ended.

Mapping task completed

Mapping Successful

When the task status is displayed as Task Completed, it means that the mapping is successful and the mapping results have been generated. At this time, you can further view the mapping results to confirm whether they meet the expected requirements. View the mapping results:

Mapping Failed

When the task status is displayed as 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 get 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.

Lossless Update Mapping for Multi-Maps

Log in to the EasyAR Development Center. Select Mega Block -> Block Mapping from the left sidebar menu. Choose the corresponding project address and click the Manage button to enter the mapping task interface.

Enter the project management interface

Create a Multi-Map Lossless Update Task

  1. Select the multi-map task that needs lossless update and click the Lossless Point Cloud Upgrade button.

    Enter the project management interface

  2. Enter the task name in the pop-up dialog box, select the mapping version and data format (it is recommended to use the latest version). After filling in, click Confirm Add to create a multi-map point cloud lossless update task.

    Enter the project management interface

Add Auxiliary Mapping

After the multi-map lossless update task is created, it is necessary to add an auxiliary mapping task for each independently collected area.

  1. Click Multi-Map Fusion Management to enter the corresponding multi-map fusion management interface.

  2. Click Add Auxiliary Mapping, enter the task name and click Confirm to create a sub-map. Note that an auxiliary mapping task needs to be created for each independent collection area.

Data Preparation

Before uploading data, it is necessary to ensure that the collected spatial data meets the requirements and is sorted and stored according to the specifications. The following content will detail the data collection equipment and the naming, storage, and structure specifications of data files.

Upload Data

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

Explanation of data upload location: Select Local New Data or Aliyun Disk Link to upload.

Upload data for multi-map lossless update

Start Multi-Map Lossless Update Mapping

The operation process of multi-map lossless update mapping is the same as that of multi-map fusion mapping. For specific operation steps, refer to the Start Mapping for Multi-Map Fusion Tasks section.

Confirm the Mapping Results

After the task enters the mapping process, you can judge whether the mapping task is completed through the Task Status. When the status of the multi-map lossless update task is displayed as Task Completed, Mapping Results Are Not Ideal, or Generation Failed, it means that the mapping task has ended.

Mapping task completed

Mapping Successful

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

Explanation of mapping results:

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

  • Mapping Results Are Not Ideal: The mapping is completed but the fusion is poor. The mapping result is multiple Mega Blocks. Mapping results are not ideal

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

    • Collection route specification: Ensure that the collection route meets the specifications and the overlap requirements are met between different sub-maps. (Reference: Collection Specifications)
    • File upload integrity: Ensure that all files have been uploaded without omission. (Reference: Preview Uploaded Files)
    • Collection area coverage: Ensure that the collection area covers all requirements without missing any areas. (Reference: Review the collection route)
    • Accuracy of manual association: If manual association mapping has been performed, ensure that the sub-map relationships are specified accurately. (Reference: Manual Association 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.
