POP 2 3D Scanner User Manual

Scan Accuracy/ Mode Introduction

Scan Accuracy: Fast Scan and High Accuracy Scan

Fast Scan: It can make users quickly scan an object, but the accuracy in this mode is relatively lower than high-accuracy scan.

High-accuracy Scan: It's added to meet users' needs to higher-precision data capturing. In High-accuracy mode, the processing time for point

cloud fusion/mesh/texture will be relatively longer.

The differences among these 5 modes are mainly exposure and gain settings:

·Feature mode: Designed to scan objects with unique shapes such as sculptures and easily-identifiable features.

· Marker mode: Designed to scan objects that have large, smooth areas or regularly-repeating features that could fool the POP 2's internal

pattern recognition capabilities. Flat planes like a board or symmetrical objects like balls or bowls are usually suitable to scan

with this mode. Place tracking markers irregularly on or around the objects. Remember to distribute the markers so they do not

have repeating patterns because the scanner determines the relative location of each frame of point cloud data by identifying

the unique patterns formed by the markers. Plan ahead to keep six or more markers in view for each frame during the scanning

process.

NOTE: *Marker mode is not available with the Wi-Fi (Hotspot) connection (the data link is too slow for the interactive

procedure used by this mode to track the patterns).

·Face mode: Designed to scan the human face. The exposure and gain are set according to typical skin reflectivity (no Automatic exposure

adjustment).

·Body mode: Designed to scan a human body or larger objects from a greater distance than is used for the other modes. The exposure and gain

are set accordingly (no Automatic exposure adjustment).

·Dark mode: Designed to scan objects with darker surfaces, such as black or dark gray clothes, black boxes, dark hair, etc. However, not all

dark objects can be successfully scanned. One example would be black leather shoes because leather absorbs light (or they are

so shiny that they reflect too much light). The exposure and gain are set accordingly (no Automatic exposure adjustment).
