Education

 

PhD candidate

Dates: January 2009 – (June 2012)

Topic

one-shot dense pattern projection for measuring moving surfaces.

 

At the moment my research activity is focused on the problems of 3D retrieval from Structured Light (SL). I started my PhD with a deep analysis of the state of the art in SL [1]. Then, I focused on one-shot pattern, able to work in moving scenarios. Among them I studied the so called fringe pattern, which extract dense 3D structure by a frequency analysis of the recovered image. I proposed a new fringe pattern for absolute dense reconstruction [2]. Posteriorly, I developed a new fringe analysis algorithm to improve the accuracy of depth extraction [3]. I am currently working on the development of a one-shot DeBruijn based algorithm which includes the techniques of fringe analysis to obtain a dense and accurate 3D retrieval [4]. Also, I have proposed a pseudo-random pattern for stereo-vision applications [5].

Besides, I have studied the problem of projector calibration, and implemented a new algorithm for projector-camera planar-based calibration [6], [7].

Institution and professor

My supervisor is the prof. Joaquim Salvi, of the Department of Arquitectura I tecnologia de computadors, University of Girona (Spain). Joaquim Salvi is considered an expert in SL, having more than 1250 references most of them in SL and projector and camera calibration.

Moreover, I have done two international stages to study specific sub-topics of my PhD:

 

 

Mobility stage

Registering of single view Structured Light images into a composed multi-view 3D image of the scene. This involves the study of global and local feature descriptors for 3D clouds of points, and the development of a suitable global descriptor for 3D points obtained from SL.

Institution and professor

Prof. Andrea Fusiello and prof. Umberto Castellani, of the Department of computer science of the Università degli studi di Verona (Italy).

 

 

Mobility stage

Dates: June 2010 – October 2010
