can be measured. This need for 3D scanning systems, which arose from the need for production from clay models in the automotive industry, has begun to be used frequently in the fields of retrospective engineering and quality control.

3D scanning systems are divided into two main groups: touch and non-touch systems.
They are touch or probe systems, mechanical arm systems and CMM. A few
Thanks to a measuring probe attached to the end of the axis mechanical arm, the coordinates are adjusted to the desired point.
The coordinates of the point are measured precisely with the touched probe. Surface information with these systems
The coordinates of a certain number of points can be obtained.
Obtaining free-form surface information with non-touch optical systems is important for both product development and

is getting ready.
Although there are various types of 3D scanning systems and non-touch systems and each has different usage areas,
laser line systems and structured light pattern (grid projection, fringe) systems or
Topogrammetric systems are more commonly used than others.
Laser line systems, among the non-touch optical scanning systems, create a laser cross-section on the object.
They work on the principle of dropping the object and moving this section on the object. Measurement

can be brought. An example of these systems is Steinbichler T-SCAN. A portable system
Because of this, the products to be digitized can be scanned in their own environment. Thus
Time-consuming pre-scanning preparations are eliminated. Even inexperienced people
With this system that can be used, scanning by moving as if painting with a paintbrush
It is performed and can be viewed in real time on the monitor during scanning. 90mm
It allows scanning of large objects with its scanning width.

Retroactive engineering provides solutions to such requests and problems. Digitization systems are used as a technological convenience in solving these processes. The part is digitized through these systems and can be made ready for CAD model creation.
