RevoPoint Trackit: a 3D scanning system with motion tracking
The Trackit from RevoPoint represents an innovative approach to capturing the geometry of objects that challenge conventional 3D scanners. This system is based on real-time motion tracking to digitize large-scale elements or those that do not remain static, significantly expanding the possibilities in the field of 3D digitization. 🚀
Key components of the Trackit system
The core of the system is a tracking bar equipped with infrared cameras and a structured light projector. This component is complemented by reflective adhesive markers and a handheld scanner from RevoPoint's Pop 2 or Mini 2 series. The bar acts as the spatial reference center, constantly tracking the position of the markers as the user moves the scanner around the target.
Workflow for scanning:- Place the reflective markers at strategic points on the object to be digitized.
- Set up and calibrate the workspace so that the Trackit bar can see the markers without obstructions.
- Move the handheld scanner around the object, allowing the system to merge position data with the captured point cloud.
The tracking technology frees the user from the need to keep the object completely immobile, a fundamental requirement in other methods.
Practical applications and advantages
This solution is designed to overcome specific limitations. It is ideal for digitizing automotive parts, industrial components, sculptures, furniture, or even capturing human movement for animation, as long as markers can be attached. The process generates a coherent and accurate 3D model, regardless of small movements of the object or scanner.
Scenarios where Trackit excels:- Digitizing large-scale objects that do not fit in the field of view of a fixed scanner.
- Capturing elements that are difficult to completely immobilize during the process.
- Working in environments where setting up a robotic arm system or turntable is not viable.
Considerations and a peculiar challenge
To achieve optimal results, it is crucial to plan the placement of the markers and ensure their continuous visibility to the tracking bar. A curious detail mentioned by users is the need to avoid inadvertently capturing one's own hands or body while circling the object with the scanner, a practical reminder of the system's sensitivity. The Revo Scan 5 software is responsible for finally processing and aligning all the data, delivering a ready-to-use 3D model. 🛠️
