Reconstruction of 3D shape for an object using laser scanning triangulation

Abstract EN

This paper presents a method of designing and constructing a system capable of acquiring the third dimension and reconstructs a 3D shape for an object from multi images of that object using the principle of active optical triangulation.

The system consists of an illumination source, a photo detector, a movement mechanism and a PC, which is working as a controlling unit for the hard ware components and as an image processing unit for the object multi view raw images which must be processed to extract the third dimension.

The result showed that the optical triangulation method provides a rapid mean for obtaining accurate and quantitative distance measurements.

The final result's analysis refers to the necessity of using laser light in the active optical sensing technique for its unique characteristics.
