First look

Let’s take a brief look at the Polyga H3’s compact design with numerous handy features.

With two ultra-fast cameras mounted at the right angle, the H3 is able to provide highly accurate results with a point-to-point distance of 0.5 mm.

Since the model comes in two versions, one can choose the option for their specific needs — for monochrome or full-color scanning.

All connectors and a power button are located at the bottom of the rear panel, which ensures free, natural movement during the process.

As for the important interface buttons, they are mounted above the handle for the user to quickly pause or resume scanning when needed.

The mentioned properties make for a smooth and convenient workflow for both new and seasoned users.


Getting started

First, one should connect their H3 scanner to get to work. The process is really easy and will take mere minutes.

Start with adding your scanner via Network Configuration Tool. Select the Ethernet port that your device is connected to and choose the Scanner Default option to apply the correct IP settings.

You can view your new and current settings at any time. If you are satisfied with the provided info, click the Test button to make sure the connection is successful.

If it is, you will see the following screen providing all the necessary data of your device.

Then, select the Scanners panel to add the H3 in FlexScan3D software. Choose the appropriate series type and wait for the program to find the device.

When it is done, you will see the following window displaying the current status of the connected scanner.

Once this step is reached, you can proceed to the Project tab and start a new scanning project.

The device is now completely ready for operation, no calibration required.


Scanning process

Let’s go over the main points of the scanning process with the Polyga H3. The procedure is through the FlexScan3D software boasting a number of automated algorithms for easier and better-quality data acquisition.

To begin scanning, just pick up the device and press the Scan button. Move the scanner slowly and surely to ensure smooth and consistent tracking for more precise outputs. Feel free to rotate the device to cover all the angles of the object to get the most complete dataset.

The Polyga H3 provides exceptional quality of data capturing, which is demonstrated by the example of this sweater scan: every single weave and detail is reflected thanks to the device’s industrial-grade cameras.

If the scanner loses connection or tracking of the object, the Auto-Realignment function will allow you to resume scanning without restarting the project.

When you need to reposition yourself or the object, press the Pause button to freeze the scan. To resume the process, just press the same button again.

If you need to set a cut plane, take a quick scan of the object and pause the process.

Select the part of the dataset to assign it for the future cut plane and apply the changes before resuming the process.

After this, the plane underneath the object (such as the table) will be automatically cut out, thus leading to reduced post-processing time.

When you resume scanning, the data out of the cut plane will no longer be recorded. So, you will get a clean dataset according to your requirements.

Furthermore, you can easily switch between two alignment modes. Choose the standard one for objects with complex geometry features, like the human body or clothes, and the strict alignment mode for simpler forms, for example, mechanical parts.

Since over- or underexposed objects can cause problems during scanning, do not forget to tweak the Gain and Brightness settings according to your environment prior to scanning. 

Start by adjusting the Gain and proceed to the Brightness for further improvement of your future scans. Red color indicates overexposure, while blue or black marks underexposure.

To find the correct settings, you should see the object clearly in the preview screen. This will allow you to obtain better scans.

In the next screenshot, you can see the difference between the overexposed and normal scan.

As a hybrid 3D scanner, the H3 model can be used in either handheld or stationary mode depending on the user’s needs. To operate the scanner in the second mode, attach it to the dedicated tripod and place the object on the rotary table. No additional calibration is required.

Soon, you will get a complete scan with all the visible angles ready for post-processing.

To sum up, scanning with the Polyga H3 device is really simple and highly productive.
