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.

Collect file management

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

Data collection for mapping

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

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

   When the value changes from Not Tracking to Tracking, it indicates successful initialization. At this point, you can lift the phone and click the red circular button at the bottom to start collecting data by pointing at the target area.

Collection status monitoring

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

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

Note

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

Visual auxiliary feedback

During the capture process, the system will generate camera view frustums and motion trajectory lines in space in real-time.

Cone feedback

Viewing frustum: Represents the camera position and orientation of current and historical keyframes.

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

Through this visual feedback, users can intuitively evaluate the coverage completeness of the collection area, ensuring the quality of the mapping data.

Turn off view cone feedback

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

End collection and save results

Click the red square button to stop recording.

1. Enter name: Input the name of the current collected data in the save interface.

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

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

4. Local storage: After confirmation, the system will write the collected data files to the local storage space of the phone.

Record management and deletion

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

1. Select a record: Click on 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.

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