Mobile object acquisition checklist
The following is the checklist required for collecting mapping data via the mobile Mega Toolbox. You can refer to the corresponding checklist items before acquisition, during acquisition, and after acquisition as a quick reference for the collection workflow. This ensures effective, high-quality mapping data, thereby improving localization stability.
Tip
You may print this checklist before each acquisition for reference.
Preparation stage check (must do before acquisition)
☐ Prepare an iPhone supporting ARKit or an Android phone supporting ARCore
☐ Install the latest version of Mega Toolbox App
☐ Ensure phone battery exceeds 50% to avoid mid-process shutdown
☐ Ensure storage has over 5 GB free space to prevent data save failures
☐ Ensure ambient lighting is suitable—avoid strong backlight, direct sunlight, or overly dark environments
☐ Ensure the phone lens is clean—avoid fingerprints, oil stains, or dust affecting camera imaging
Acquisition process check (reference during on-site operation)
☐ Throughout acquisition, the top-left status must remain Tracking. Maintain steady movement—avoid rapid turns or abrupt stops
☐ Acquisition duration must not exceed 15 minutes. Exceeding this will force termination and trigger the save page
☐ Do not switch to background apps during acquisition—this will cause failure
☐ Avoid prolonged pointing at plain surfaces (e.g., white walls, metal), reflective areas, or transparent glass
☐ Strictly follow the acquisition workflow. Scan the environment comprehensively from multiple angles, including circling, tilting up/down, and combining near/far views to enrich perspective data
☐ Ensure the acquisition video covers the entire target object
☐ Avoid obstructing the lens with hands or other objects
☐ If acquisition fails, restart the process
Post-acquisition check (must do before upload)
☐ The acquired data file extension is .emp. Verify the filename suffix during export
☐ After exporting to a computer, use PotPlayer or VLC Media Player to review the video. Check for blurriness, lag, or playback failure—re-collect if issues exist
