[Guide] How to use Mark Mode to scan objects?

As you know, the objects with geometrical features and complex shapes, you can scan them 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 scanning 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 the desk with markers;
3.Place an object on a turntable with markers;

In 2 &3 methods, the relative position of an object and a turntable/desk 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;
c. Select “Marker” mode;

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

e. Scanning;

The First Model Scanning

  3. Complete scanning;

  4. Export 1st model;

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

The Second Model Scanning

  3. Scan 2nd circle;

f. Merge;

  2. Mark on models;

  3. Merge;

Note:

  1. Scanning repeatedly can’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.

Thanks for this tutorial, it’s just what’s needed.
Perhaps some others for general scanning as well would be good?

Where do we download Handy Studio?
I have Handy Scan but not studio…

Handy Studio is installed to this place with HandyScan.
“C:\Program Files\HandyScan\HandyScan\mtp\ModelProcessTool.exe”
Probably, your can see app short cut on your windows desktop.

What adjustments to exposure and gain do I make? What is good exposure, what is bad? What is good gain, what is bad?
