Speckle noise reduction from laser scanner acquitions

The thesis is in the field of Computer Vision for Industrial applications.

The aim is the reduction of speckle noise from laser scanner acquisitions on steel rods at Tenaris Dalmine Company.

The system is based on a laser line projected on the object and a 3D reconstruction system based on two or more cameras. The thesis will develop an accurate calibration system to accurately determine cameras distortion parameters and their relative position with respect to the laser blade. Further geometrical constraints like trifocal tensor will be adopted in order to strength the calibration accuracy and to remove artifacts due to speckle noise.
