Mega data acquisition
Data acquisition is the first step in building an EasyAR Mega spatial map, and it is also a key factor that determines the quality of the final Mega localization experience. Only after high-quality data acquisition is completed can the subsequent mapping and localization processes proceed smoothly.
This module mainly introduces how to capture environmental video data through supported devices and 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 scenario requirements at different scales:
- Mobile phone acquisition: For small and medium-sized scenarios such as small spaces and objects.
- Apple devices: iPhone11 and later devices
- Android devices: Devices that support ARCore (except devices disabled by EasyAR), view supported device details
- Panoramic camera acquisition: For large-scale spaces such as shopping mall atriums, streets, and squares. A panoramic camera can capture 360-degree environmental information at once, with acquisition efficiency 3-4 times that of a mobile phone and fewer localization blind spots.
- Currently supports GoPro Max and GoPro Max2 panoramic cameras.
Choose a data acquisition method
Using a panoramic camera or mobile phone to acquire target data, you can choose the appropriate data acquisition process according to your application scenario.
| Acquisition method | Applicable scenario | Acquisition device | Acquisition duration |
|---|---|---|---|
| Regular single-image acquisition | Large spaces (shopping malls, museums) | GoPro Max /Max2 | Within 128 minutes |
| Very large space acquisition | Very large spaces (large scenic areas, continuous streets) | GoPro Max/ Max2 | Default within 5 x 128 minutes (can be increased by contacting business) |
| Mobile small-area acquisition | Small spaces (rooms, stores, showrooms) | iPhone / ARCore Android phone | Within 15 minutes |
| Mobile specific-object acquisition | Single objects (exhibits, devices, products) | iPhone / ARCore Android phone | Within 15 minutes |
