3-dimensional object scanning and modelling via computer vision

The operation of passing a laser beam on the surface of a real-world object for acquiring its 3D shape data is called laser scanning. Laser scanning has usages like acquiring a patient's 3D body model for a medical operation, finding the shape errors of the objects in a production line, or a robot's discovery of its environment's 3D shape.To meet the requirements of the different industries, different laser scanner software or hardware products exist. However, some of these products are designed for their special purposes and cannot be used for other purposes. For example, a laser scanner designed to find the shape errors of objects on a production line, might be designed only for that purpose so that it can't be used to acquire the shape information of a patient in a hospital or it can't be used by robot as an environment sensor.This thesis presents a study on laser scanning using the laser triangulation method. In this application, the images of a surface marked by a vertical laser beam are recorded by a camera and processed by a software called "YakarTarar", which was developed during the studies. As a result of this processing, the 3D model of the surface is saved in the computer.The goals of YakarTarar software are to meet different requirements of different industries and to have a minimal base cost.
