Mobile small-scale space acquisition checklist

The following is the checklist required for collecting mapping data through 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 acquisition process. This ensures effective, high-quality mapping data and improves positioning stability.

Tip

You can 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 the Mega Toolbox App

☐ Ensure the phone battery level is above 50% to avoid sudden shutdown

☐ Ensure the remaining storage space is over 5 GB to prevent data saving failures due to insufficient space

☐ Ensure appropriate ambient lighting, avoiding strong backlighting, direct sunlight, or overly dark environments

☐ Ensure the phone lens is clean, free of fingerprints, grease, or dust that may affect camera imaging

Acquisition process check (reference during on-site operation)

☐ Throughout the acquisition, the top-left corner of the acquisition interface must remain in the Tracking state. Maintain steady acquisition and avoid rapid turns or sudden stops

☐ The acquisition duration must not exceed 15 minutes. Exceeding this limit will force the acquisition to end and enter the saving page

☐ Do not switch to the background during acquisition, as this will cause the acquisition to fail

☐ Avoid prolonged focus on plain surfaces like white walls, metal, or reflective/transparent areas like glass

☐ Strictly follow the acquisition process. Scan the environment comprehensively from multiple angles, including circling, tilting up and down, and combining near and far distances to provide richer perspective information

☐ The acquisition video must cover the entire target object

☐ Avoid blocking the lens with hands or other objects during acquisition

☐ If the acquisition fails, restart the process

Post-acquisition check (must do before uploading)

☐ The acquired data file extension is .emp. Pay attention to the filename suffix when exporting

☐ After exporting the file to a computer, use PotPlayer to check the recorded video for blurring, lagging, or playback issues. If any issues are found, reacquire the data
