Is my localization database ready to use?

Congratulations! Now that you have an understanding of how Mega works, its applicable scenarios, device support, and have learned how to obtain and use an APIKey, your application already has the foundation for achieving high-precision spatial localization.

Before you begin

Before you start writing the application logic, please ensure:

1. The localization database has the correct map added
   Check your localization database to ensure it has the map for the area your application needs to use.
2. The SDK is configured correctly
   Confirm that you have correctly initialized the EasyAR SDK in your code, configured a valid SDK License, and passed a valid API Key for the Mega service.
3. The map is correctly referenced
   In your scene or code, ensure that the Mega localization module (such as the MegaTracker component) correctly points to the map resource you added.

If the above steps are completed, your localization database should theoretically work normally.

Encountering issues

If you encounter issues while checking the above steps, refer to the following articles for solutions:

• You don’t have a map yet
  You need to first create a Mega map for the target physical space. This usually involves two steps: data acquisition and mapping. Refer to:

  • Data acquisition
  • Mapping

• You have a map but are unsure of its quality
  The accuracy and coverage of the map directly affect localization performance. You can check the mapping results to help you evaluate. Refer to:

  • Reviewing acquisition routes
  • Viewing the mapping report
  • Previewing the 3D textured mesh

• About map loading and management
  For how to load and manage mapping results in the localization database, refer to:

  • Managing the localization database
  • Verifying the localization database

• SDK License and APIKey
  If you encounter issues related to the License or APIKey, refer to:

  • EasyAR Sense license
  • Obtaining and using an APIKey

When your project includes valid and high-quality Mega maps, your localization database is truly ready. Please refer to the above documentation based on your specific situation to complete the preparation and configuration of the map, and then you can start writing exciting AR applications!
