Mobile object acquisition checklist

The following is a checklist required for collecting mapping data with mobile Mega Toolbox. You can check against the corresponding checklist during before acquisition, during acquisition, and after acquisition as a quick reference for the acquisition process, so that effective and high-quality mapping data can be obtained and localization stability can be improved.

Tip

You can print this checklist before each acquisition and check against it.

Preparation check (must be done before acquisition)

☐ Prepare an iPhone that supports ARKit or an Android phone that supports ARCore

☐ Install the latest Mega Toolbox App

☐ The phone battery should be above 50% to avoid power loss during acquisition

☐ The remaining storage space should be more than 5 GB to avoid acquisition data save failure caused by insufficient phone space

☐ The ambient light should be suitable. Avoid strong backlight, direct sunlight, and overly dark environments

☐ Make sure the phone lens is clean. Avoid fingerprints, oil stains, dust, and other factors that affect camera imaging

Acquisition process check (reference during on-site operation)

☐ During the entire acquisition process, the upper-left corner of the acquisition interface must remain in the Tracking state. Keep acquisition smooth throughout and avoid quick turns or sudden stops

☐ Acquisition duration cannot exceed 15 minutes. If it exceeds 15 minutes, acquisition will be forcibly ended and the save page will be entered

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

☐ Do not aim at plain-color surfaces such as white walls and metal, or reflective and transparent glass areas for a long time

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

☐ The acquisition video must cover the entire target object

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

☐ If acquisition fails, start acquisition again

Post-acquisition check (must be done before upload)

☐ The extension of data collected by the phone is .emp. Pay attention to the file name suffix when exporting

☐ After the file is exported to the computer, you can use PotPlayer or VLC Media Player to play the recorded video and check whether there are blurring, stuttering, or playback failures. If there are problems, acquire again
