The Thor3D Calibry 3D Scanner represents a new generation of Thor3D devices. It is installed with a newly-developed high-precision proprietary camera. Thanks to being equipped with such a high-end solution that can now be manufactured right at the company’s factory, the scanner is now sold at a reduced price while offering improved accuracy and other features. The body of the scanner is made of impact-resistant plastic and it weighs just 900 grams. Its 2.3-megapixel camera operates at 3 million points per second and offers an accuracy of 0.1 mm (100 microns). Thanks to the advanced capturing algorithms, the Calibry will have no problems while capturing hard-to-scan objects like sharp edges, human hair, and black or shiny surfaces. 

Thanks to being affordable, reliable, and easy to use, the device became really popular with engineers, doctors, and teachers.

 

Mode of Operation

The Calibry is a handheld 3D scanner that can create precise three-dimensional renders of medium and large objects (from 20 cm to 10 m) by employing a renowned structured light 3D scanning technology. This technology is especially good at scanning human faces and bodies, as slight body movements (e.g. breathing, eyelid movements) don’t affect the final result if there was a slight offset during scanning.

In essence, the structured light technology is powered by a reference geometric pattern projected onto the surface of an object. Then, the camera of the scanner receives the distorted pattern of the scanned object, while the computer analyzes it and recreates the object's surface depending on the received reference pattern. The more points you scan from different angles, the more accurate the final render will become.

What’s in the Box?

The scanner is shipped in two separate packages - there is a case with the scanner and a box with a calibration plate. Please keep in mind that the latter is a large one and will require quite a lot of space. Inside the box, you will find the calibration plate folded in half and all the pre-assembled mounts and fasteners to hold it in place. There’s also a stand for the scanner.

The case contains the scanner itself, a power cable, and two wires - one should be used to connect the scanner to the hub, and the other one is needed to connect the hub to the computer. The case also contains the hub itself, a set of markers, and a user guide.

You can download the software suite from the Thor3D website for free.

 

Software 

Calibry Nest

Calibry Nest is a powerful 3D scanning solution that lets the user control the device via a built-in touchscreen. Just like that, you can turn the scanner on or off and begin or finish the scanning process, as well as adjust different scanning parameters such as brightness, sensitivity, mesh, and switch between different tracking modes (geometry, markers, or texture). All the rendered data will be transferred to the connected PC that also displays the battery level, markers, and calculates the object distance.

All the necessary post-processing is carried out by the software installed onto the user’s computer. To speed up the workflow of entry-level users, Calibry Nest can operate in two different modes, namely: "Simple" and "Advanced".

By using the “advanced” mode you can:

  • Simplify the model by reducing polygonal data;
  • Automatically align several scans into one;
  • Lighten or darken texture;
  • Get rid of noise;
  • Cut out unwanted bits of geometry;
  • Create a watertight mesh;
  • Work on each frame individually or a group of frames simultaneously;
  • Split or merge your projects;
  • Use sophisticated algorithms to accurately fill holes even on objects with complicated geometry;
  • Smooth geometry over the whole model or in one particular spot;
  • Adjust model sharpness;
  • Automatically remove markers from the scan;
  • Export into one of four industry-standard formats (obj, stl, ply, wrml);

In our opinion, the Calibry is a flexible and powerful 3D scanner that can be used in a wide array of professional and industrial applications. Compared with other professional 3D scanners, the Calibry comes first in almost every parameter comparison. It is a lightning-fast device that can be controlled via a touchscreen and costs less than most of its analogs.

Let’s quickly compare between the main specs of the Thor Calibry and Shining 3D Einscan Pro 2x 2020:

Use Cases

Scanning of a Statue

Sergei Polegaev, a well-known Russian sculptor, wanted to obtain a 3D model of his statue to 3D print its smaller version. The model had to be scanned with the utmost accuracy because the sculptor wanted to convey even the smallest details.

To organize the scanning session in a streamlined and efficient way, the scanned object has been placed on a turntable. First, the Thor3D team scanned the back of the head and shoulders of the statue. Then, as the turntable rotated, they moved the scanner down and up again once reaching the bottom, scanning in a swift non-stop fashion.

After dealing with quality assurance, the specialists ran additional 3D scannings on the armpits of the statue. By using Calibry Nest, all of the subsequent scans were “stitched” together and united with the first scan, thereby forming a precise three-dimensional render of the statue. The scanning has been completed in just 7 minutes, while model editing and all the related post-processing business took 15 minutes. The final resolution was set at 1 mm.

As you can see, the Calibry captured even the smallest marks left by the sculptor's tool.

“The whole 3D scanning business took several minutes to be completed. We and our visitors enjoy using such a uniquely designed device” - says the 3D scanned employee.

  

Our Experience

We couldn’t miss the opportunity and decided to stress-test the Calibry ourselves. Besides, we decided that the scanning should be performed by an employee with no 3D scanning experience.

  

Render of a Human

Right off the bat, our employees noted that the scanner is somewhat tricky to position and calibrate correctly. Initial attempts to calibrate the scanner while holding it were unsuccessful, as the slightest vibration interfered with the calibration outcome. It took a couple of attempts, but in the end, the scanner was calibrated and ready to go.

After creating a couple of scans, we aligned them together by using the Calibry Nest software. Thanks to its features, we could create a highly accurate 3D model without any disturbance. 

  

3D Scanning a Michael Jordan’s Bust

After successfully creating a high-definition human render, we decided to scan a 3D printed bust of Michael Jordan, a legendary basketball player.

This time, we didn’t have to stitch different scans together, so the process went quite smoothly. We received the final render in a couple of clicks. 

   

Bas-Relief Render

For our third project, we decided to create a 3D render of a bas-relief and had to scan a flat metal object with intricate geometric patterns that made it particularly hard to scan. 

To achieve maximum accuracy, we performed 3D scanning while using tracking by geometry and markers. The geometry-tracked scan results turned out to be poor, as the scanner mixed up the frames. On the other hand, tracking by markers provided us with a high-precision render that can be seen in the image below.

The texture was added onto the final scan results. It can also be captured during marker-powered 3D scanning but won’t be added until you start texturing. 

As you can see, the intermediate result (in the photo above) looked mediocre. But it was only until we added some post-processing into the mix: 

Then, we deleted the bottom layer and saw this:

All in all, the scanner performed very well. Its markers tracking mode proved to be remarkably efficient for high-accuracy 3D scanning within 0.5 mm tolerance. 

  

Scanning a 3D Printed Statue

We employed the geometry tracking mode to create a three-dimensional render of a statue since markers could interfere with the object’s geometry. 

As you can see, the scan turned out to be accurate and well-detailed. 

The scanner performs without problems and provides precise tracking. Several reflective markers are remaining on the statue, they were left after test-scanning with another device. 

After tinkering with sensitivity and resolution settings, the render became even more precise. However, as you might have noticed, it still has some noise.

The render also contains holes that appeared because of the reflective markers. It took us less than 5 minutes to delete them all by using a special brush provided by Calibry Nest.

Much better, isn’t it? You can also notice how scanning smoothened all the visible layers of the 3D printed statue and provided our model with an improved appearance. A good result indeed. It is difficult to determine the exact level of precision, but given that the sculpture's gluing seams and layers appeared on the scan, the accuracy is not lower than 0.4-0.7 mm. Therefore, we consider this device to be suitable for high-precision scanning of sculptures and other art objects.

  

Scanning an Air Conditioner

For our last project, we decided to scan an industrial air conditioner. Such a scan can be used for industrial design as well as reverse engineering. The surface of the conditioner was shiny and reflective, which made it more challenging to scan. To create an accurate render of the object, we employed the Thor Calibry in its markers tracking mode.

We decided to use the marker tracking mode because it was impossible to scan the object in one go.

Take a look at the project tree located on the left side in both of the pictures. You can see that we had to re-scan some parts of the object several times because the scanner tended to lose tracking when pointed incorrectly (at an angle).

You can see the noise located on the shiny parts of the objects.

Truth be told, the presence of a small amount of noise on a 3D model is quite natural in case you scanned an object with a shiny surface. Despite the difficult nature of the task, the Calibry helped us complete it in a streamlined and efficient way.   

 

Pros and Cons

Pros

  • Large scan volume and lightning-fast capturing speed 
  • Fair price
  • Easy to use and control. 

Cons

  • Long processing of large objects. 
  • Requires some free space because of a minimum working distance of 500 m

  

Bottom Line

After testing the limits of the Thor Calibry for more than two weeks, we are delighted to conclude that this high-end 3D scanner can become an indispensable tool for a wide array of professional and industrial applications. It can be employed in 3D scanning of art objects, statues, cars, furniture, people, animals, and more.

In our opinion, the scanner has immense potential in the development of independent game projects. Given that an indie company has an experienced 3D modeler, all of the human scans captured by the Calibry can be used to create in-game characters.  

The Calibry is a professional lightweight handheld 3D scanner that features a responsive built-in touch screen and is particularly easy to use. It comes with an advanced software suite with a lifetime license that, albeit its advanced functionality, is pretty straightforward.

You can purchase the Thor Calibry at Top 3D Shop. This lightweight, neatly-looking, and powerful 3D scanner comes with the manufacturer’s warranty. Besides, our team will make sure to provide the best service possible, just like we always do.
