Create a laser acquisition task (E57)
This article describes the complete workflow for a laser acquisition task in E57 format, including task creation, data upload, and the mapping process, helping users complete the full E57 laser acquisition and mapping workflow in a standardized way.
Create an E57 laser acquisition task
After creating a project, click Manage to enter the mapping task management page (skip this step for Mega Go). Click the Laser acquisition task button in the upper-right corner. In the pop-up dialog, enter Task name, select E57 format for Data type, use the latest version for Mapping version and Data format, and click Confirm add to create a Qiyu acquisition task.


Data preparation
Before starting a mapping task, make sure the acquired spatial data meets the requirements and is organized and stored according to the specifications. The following sections describe data acquisition and export in detail.
Data acquisition and export
Use a laser scanner to acquire spatial data. For related device configuration and acquisition points, see:
Upload data
Click Upload data and select the corresponding options in the pop-up window. See the following sections for details about each option:

Data location
The available upload methods vary depending on the region where the mapping project is located:
China Region 1
Depending on the data source and storage method, you can choose either of the following methods:
- Local new data
- Uploaded data (not supported by Mega Go)
Global
Only Local new data is supported.
Acquisition data
Upload a file with the .e57 suffix. Click Select, choose the specified file in the directory, and click Open.

Confirm upload
- After clicking
Confirm upload, the list displays the upload progress and status. - During data upload, keep the 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 must be performed again.
Start mapping
After data upload is complete, the mapping process starts automatically. The status is displayed as Queued or Generating, as shown below. Wait patiently for mapping to complete.

Auxiliary functions
The following functions help you manage and operate mapping tasks more efficiently:
View uploaded files
Click View uploaded files to view all uploaded files in the dialog and confirm that all files have been uploaded, avoiding mapping failures caused by missing files.

Stop mapping
Before the mapping task is complete, if you find that the wrong data was uploaded or the trajectory data does not match the actual situation, click Stop mapping, then click Confirm in the second confirmation dialog to stop mapping.

Delete task
If the current mapping task failed or is no longer needed, click Delete task to delete it. Click Delete in the second confirmation dialog to complete the deletion.

Confirm mapping results
After the task enters the mapping process, you can determine whether the mapping task is complete from Task status. When the status is Task complete or Generation failed, the mapping task has ended.

Mapping succeeded
When the task status is Task complete, mapping succeeded and the mapping result has been generated. You can further inspect the result and confirm whether it meets expectations.

Mapping failed
When the task status is Generation failed, mapping failed. Troubleshoot the problem as follows:
- View mapping report: View mapping report and find a solution based on the report information.
- Refer to troubleshooting: Read the mapping failure troubleshooting guide for common solutions.
- Contact technical support: If the methods above do not solve the problem, contact EasyAR staff and provide the
JobIDfrom the mapping report for fast diagnosis.
