Can My Localization Feature Be Used Now?

Congratulations! You now understand how Mega works, its applicable scenarios, device support, and how to obtain and use an APIKey. Your application already has the foundation needed to implement high-precision spatial localization.

Before You Begin

Before you start writing application logic, make sure that:

• Mega Cloud Localization
• Mega Go On-Device Localization

1. The correct maps have been added to the localization database
   Check your localization database and make sure the maps for the areas required by your application have been added correctly.
2. The SDK is configured correctly
   Confirm that EasyAR SDK has been initialized correctly in your code, that a valid SDK License is configured, and that a valid Mega service API Key is passed in.
3. The maps are referenced correctly
   In your scene or code, make sure the Mega localization module, such as the MegaTracker component, points to the map resources you added.

If all the above steps have been completed, your localization feature should be ready to work normally in theory.

Troubleshooting

If you encounter problems while checking the steps above, refer to the following articles:

• You do not have a map yet
  You need to create a Mega map for the target physical space first. This usually includes two steps: data collection and mapping. See:

  • Data collection
  • Mapping

• You already have a map but are unsure about its quality
  The accuracy and coverage of the map directly affect localization results. You can view the mapping result to help evaluate it. See:

  • Review collection routes
  • View mapping reports
  • Preview 3D textured mesh

• Map loading and management
  For how to load and manage mapping results, see:

  • Mega Cloud Localization
  • Mega Go On-Device Localization

  • Manage Mega Cloud localization databases
  • Confirm that a Mega Cloud localization database is available

• SDK License and APIKey
  If you encounter License or APIKey issues, see:

  • EasyAR Sense License
  • Obtain and use an APIKey

When your project contains a valid, high-quality Mega map, your localization feature is truly ready. Based on your situation, refer to the documents above to complete map preparation and configuration, and then you can start building exciting AR applications!
