Mobile object acquisition checklist
The following is a checklist for collecting mapping data using the mobile Mega Toolbox. You can refer to the corresponding checklist items before acquisition, during acquisition, and after acquisition as a quick reference to ensure effective, high-quality mapping data, thereby improving localization 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 storage space exceeds 5 GB to prevent data save failures due to insufficient space
☐ Ensure the environment has suitable lighting, avoiding strong backlighting, direct sunlight, or overly dark conditions
☐ Ensure the phone lens is clean, free of fingerprints, grease, dust, or other obstructions affecting camera imaging
Acquisition process check (reference during on-site operation)
☐ Throughout the acquisition, the top-left corner of the interface must display the Tracking status. Maintain steady movement, avoiding 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 save page
☐ Do not switch to other apps 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/down, and combining near/far views to provide richer perspective information
☐ The recorded video must cover the entire target object
☐ Avoid hand or other objects blocking the lens during acquisition
☐ If the acquisition fails, restart the process
Post-acquisition check (must-do before uploading)
☐ The acquired data file has the extension .emp. Verify the filename suffix when exporting
☐ After transferring the file to a computer, use PotPlayer to check the recorded video for blurriness, lag, or playback issues. Reacquire if any issues are found
