Mega data collection

Data collection is the first step in building an EasyAR Mega spatial map and a crucial factor determining the quality of the final Mega localization experience. Only by completing high-quality data collection can subsequent mapping and localization processes proceed smoothly.
This module primarily explains how to capture environmental video data using supported devices to provide high-quality raw materials for mapping.

The following diagram shows the position of data collection within the entire Mega workflow:

Supported devices

EasyAR Mega offers flexible collection solutions to adapt to different scale scenarios:

  • Mobile collection: For small-to-medium scale scenarios like compact spaces or objects.
    • Apple devices: iPhone11 and above
    • Android devices: ARCore-supported devices (excluding devices disabled by EasyAR), view supported device details
  • Panoramic camera collection: For large-scale spaces like shopping mall atriums, streets, and plazas. Panoramic cameras capture 360° environmental information in one take, with 3-4 times higher efficiency than phones and fewer localization blind spots.
    • Currently supports GoPro Max and GoPro Max2 panoramic cameras.

Data collection method selection

Use panoramic cameras or mobile devices to collect target data. Choose the appropriate data collection process based on your application scenario.

Collection method Applicable scenarios Collection devices Collection duration
Standard single-map collection Large spaces (malls, museums) GoPro Max/Max2 Within 128 minutes
Extra-large space collection Extra-large spaces (large scenic areas, continuous streets) GoPro Max/Max2 Default 5 × 128 minutes (contact business to increase)
Mobile small-area collection Compact spaces (rooms, shops, galleries) iPhone / ARCore Android phones Within 15 minutes
Mobile specific-object collection Individual objects (exhibits, equipment, products) iPhone / ARCore Android phones Within 15 minutes
