Mapping data collection tool

Developers can use this tool to quickly complete mobile mapping data collection.

Mobile mapping data collection entry

Click the EasyAR Mega Mapping Data Collection (Mobile Mapping) button to start mobile collection.

Entry

Collection file management

After entering the collection file management interface, click the blue + button at the bottom to enter the collection page.

Enter collection page

Image collection for mapping data

  1. Perform initialization: Before clicking the red circular button at the bottom, point the camera at a nearby area with rich textures (e.g., a patterned wall).

  2. Status confirmation: Observe the "Tracking Status" parameter in the data panel:

    When the value changes from Not Tracking to Tracking, initialization is successful. You can then lift the phone and click the red circular button at the bottom to start collecting data by aiming at the target area.

Collection initialization

Collection status monitoring

To ensure data collection quality, the Tracking status must be maintained continuously throughout the entire collection process.

Collection failure

Abnormal interruption: If tracking is lost during collection (status changes to Not Tracking), the system will automatically terminate the current collection task and display an error message.

Note
  1. The Tracking status must be maintained throughout the entire collection process.
  2. Collection duration cannot exceed 15 minutes. Exceeding this limit will force the collection to end and enter the save page.
  3. Switching to background mode will cause collection failure.

Visual auxiliary feedback

During collection, the system generates camera frustums and motion trajectory lines in real-time within the space.

Frustum feedback

Frustum

Frustum: Represents the position and orientation of the current and historical keyframe cameras.

Trajectory line: Records and displays the collector's movement path.

Through these visual feedbacks, users can intuitively evaluate the coverage completeness of the collection area to ensure mapping data quality.

Disable frustum feedback

To disable auxiliary tools, click the switch in the upper-right corner and deselect Trajectory Line and/or Camera Frustum.

Disable frustum

End collection and save results

Click the red square button to stop recording.

Save

  1. Enter name: Input a name for the current collection data in the save interface.

  2. Naming convention: Only English letters and numbers are supported (do not use Chinese characters, spaces, or special characters).

  3. Execute save: Click the [Save] button.

  4. Local storage: After confirmation, the system writes the collected data files to the phone's local storage space.

Record management and deletion

Users can delete redundant or unused collection records as needed to maintain list cleanliness and free up storage space.

Delete

  1. Select record: Click the target record in the management list. After selection, the background color of the entry will darken as a reminder.

  2. Execute deletion: After confirming the selected status, click the [Delete] button.

After deletion

  1. Complete operation: The record will be permanently removed from the list and local storage.
