Mega data acquisition

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

The following shows the position of data acquisition in the entire Mega workflow:

Supported devices

EasyAR Mega provides flexible acquisition solutions to adapt to different-scale scene requirements:

  • Mobile acquisition: For small spaces, objects, and other medium-to-small-scale scenes.
    • Apple devices: iPhone11 and above
    • Android devices: Devices supporting ARCore (excluding devices disabled by EasyAR), view supported device details
  • Panoramic camera acquisition: For large spaces such as shopping mall atriums, streets, and squares. Panoramic cameras can capture 360° environmental information at once, with an acquisition efficiency 3-4 times that of mobile phones and fewer localization blind spots.
    • Currently, only GoPro MAX 1st generation is supported

Data acquisition method selection

Use a panoramic camera or mobile phone to capture target data. You can choose the appropriate data acquisition process based on your application scenario.

Acquisition method Applicable scenarios Acquisition device Acquisition duration
Regular single-map acquisition Large spaces (malls, museums) GoPro Max Within 128 minutes
Extra-large space acquisition Extra-large spaces (large scenic areas, continuous streets) GoPro Max Default 5 × 128 minutes (can contact business to increase)
Mobile small-space acquisition Small spaces (rooms, shops, exhibition halls) iPhone / ARCore Android phone Within 15 minutes
Mobile specific-object acquisition Single objects (exhibits, equipment, products) iPhone / ARCore Android phone Within 15 minutes
