Project Description

3D Digitizer

Device that enables the recording of the object surface and its reconstruction on a computer as a cloud of dots.

3d Digitizer platform

Three-dimensional digitization of objects is the process of registering and processing of dots from the object surface and reconstruction of their spatial coordinates in the computer in order to obtain true computer representation of the object surface. The device that conducts the process of digitization is called digitizer. Digitizers can be contact and contactless. Leading direction in development of this system was the problem of static deformities of the spine in the school population.

By using computer and obtained surface measurements and analysis is conducted in order to determine the asymmetry, size and shape of individual anatomic and topographic features of the spine, and generally to determine pathological changes from the referent norms for particular age and sex of examine.

3d digitizer

It is important to emphasize that this method of digitizing is completely safe and easy to use, and as such can be quickly implemented in the health system, while the cost is considerably more affordable than other available methods. System for digitizing is made of an linear axis which is fixed to the portal with the digital camera and laser line module. Generator of laser beam illuminates the object, creating a curve on the surface of the object, which is being recorded by a digital camera. Upon completion of recording of one section, portal linearly moves to the next known position from which the whole process repeats. As a result, a cloud of dots composed of a series of curve segments is generated, which are being processed, visualized and analyzed. The accuracy of this system is 0.25 mm which makes it appropriate for the mentioned purpose.
