Calibry Mini - Scanner 3D

Calibry Mini is a high-precision professional handheld 3D scanner developed by the renowned Thor3D, a Russian company based in Moscow specialising in the production of professional 3D scanners.

Thor3D has a dynamic and highly qualified team of engineers and mathematicians in charge of developing the complex reconstruction algorithms responsible for the high quality of the models obtained with their equipment.

Some of its algorithms and developments are so novel that many of them are protected by international patents.

Calibry Mini is a structured light scanner, one of the most widely used technologies today due to its excellent resolution/cost ratio and high accuracy. Thanks to a custom-developed camera with calibrated lenses, it captures the deformations of patterns projected onto the surface of the part and can reconstruct the geometry using complex algorithms.

Speed and precision

Calibry Mini has been developed to be able to scan small objects between 2 cm and 30 cm in length with high quality. This is thanks to its extremely high accuracy of up to 0.07 mm and its high resolution of up to 0.15 mm.

It has a custom-developed camera capable of capturing up to 30 images per second and a multi-core processor, which allows it to acquire up to 3 million points per second. This makes it possible to obtain high-density point clouds quickly and accurately.

Three scanning modes

Calibry Mini has a 4-inch touch screen that allows all settings to be configured and files to be managed. This streamlines the workflow as there is no need to access the computer at any time during the scanning process.

Calibry Mini allows the use of three different tracking modes: geometry, texture and markers. This makes it possible to precisely align captures on all kinds of objects.

Texture tracking is recommended for objects with little geometry but ample contrasting textures, especially antiques or museum artefacts, too fragile and precious for the use of markers. The geometry tracking mode can be used for scanning body parts or objects, and the marker tracking mode for capturing anything with a smooth, shiny or transparent surface, such as a car.

In addition to the main camera, it also incorporates a second texture camera that not only allows texture tracking during the scanning process, but also captures textures and colours for later incorporation into the model.

Complex feature detection

To obtain quality point clouds and meshes, in addition to advanced hardware, it is necessary to implement quality reconstruction and processing algorithms. Thor3D has developed and implemented in Calibry Mini some of the most advanced algorithms on the market, both for point cloud capture and mesh processing.

These algorithms allow high quality capture of complex elements such as sharp edges, shiny surfaces or hair. In addition, efficient interpolation algorithms are available to repair defects or holes in the mesh, making it possible to recover areas that could not be scanned.

Calibry Nest

Calibry Mini incorporates the Calibry Nest software solution, a combination of two software packages that work together, one embedded in the 3D scanner itself and the other in the computer, to automate the workflow and cover all the necessary steps to obtain a quality final mesh.

The embedded software allows all functions required during the 3D scanning process to be performed from the scanner's own touch screen. These functions include managing files, setting sensitivities, selecting the 3D scanning mode and starting and stopping the capture.

The software installed on the computer, in addition to having the same tools as the one embedded in Calibry Mini, has an advanced module for point cloud processing with tools for alignment, interpolation, simplification and mesh processing and repair.

The Calibry Nest software is regularly updated and does not require a licence. This means that the scanner can be used at facilities such as research centers or schools, with the software installed on multiple computers for one scanner only.

Calibry is the most affordable professional scanner with advanced features on the market for 3D scanning of small objects. Its friendly and powerful software included with the product allows for straightforward and quick scanning in various sectors such as engineering (reverse engineering, quality control), medicine (prosthetics), automotive, biometrics (identification), education, art and design, heritage conservation or computer graphics and animation. Its built-in screen, light weight and 3 tracking modes make it a versatile and comfortable to use tool.
