[Guide] How to Scan Object with Marker Mode

Introduction

Objects with geometrical features and complex shapes, scan with “Feature” mode directly;

However, when scanning objects like cups or boxes with simple geometric features, please scan with markers. Then select “Marker” mode.

Scanning Methods

There are three s canning methods :

  1. Stick markers on the surface of an object;

    Here follows a car scanning video: Revopoint POP Object Scan 7, Scan a car - YouTube

2.Place an object on a turntable with markers;


In this method, the relative position of an object and a turntable cannot change.

To ensure that, you shall export several models of an object to merge a complete 3D model.

For example:

a. Raise the tripod to make the POP and markers being approximately 45°- 60°;

b. Adjust an “Excellent” distance;

Note: Check “√" in Clip plane.

c.Select “Marker” mode;

d.Adjust “Exposure” and “Gain” values;

e. Scanning

1st model scanning:

1)Start to scan;

2)Make sure Markers valid (more than five red dots in the center window);

3)Export 1st model;

4)Name the model Cup 1, save in ply., obj., or stl.;

2 nd model scanning:

  1. Turn the cup over;

  2. Start to scan;

3)Scan 2nd circle;

4)Export the 2nd model in ply., obj., or stl.;

f.Merge
1)Models imported in Handy Studio;

2)Mark on models;

3)Merge;

Note:
1)Scanning repeatedly couldn’t help the accuracy, and only a closer distance can improve it.
2)If necessary, you can scan more than 2 models to merge them into a complete one.

I tried marker mode on a free floating object. Unfortunately tracking is really bad. I think the software needs alot of improvements. With feature mode it was much easier to scan. However, I want to use marker mode, because of the better accuracy.
Any tipps?

Hi @mapper ,

Yes, we will keep improving the software, please don’t worry.

For the Marker Mode, please make sure that 5 or above red dots are available during your scanning process.

Hi, I have a new Pop2 scanner. Can I use different size markers, for example, 6mm white dots with a back circle around them, too? Thanks!

From tests i have seen most markers that are available will work ok,

I think @PopUpTheVolume has done some testing and is trying some new ones with the MINI, i don’t know the limits on size though, I try to use feature mode for smaller stuff ,face mode and body mode for bigger stuff with the POP2, i haven’t tried markers with the MINI yet as feature mode works really well on the MINI, i find adding features better than adding markers

Yes you can do that , 6mm for white circle will works as I was using 6mm before.
The sizes of markers works in any size with POP2 .

Size for the white dot
0.8mm
1.5mm
3mm
6mm
