Resumen

This thesis explores the use of computer vision to facilitate three different processes of a quarry's operation. The first is the blasting process. This is where operators determine where to drill in order to execute an efficient and safe blast. Having an operator manually determine the drilling angles and positions can lead to inefficient and dangerous blasts. By using two cameras, oriented vertically, and separated by a fixed baseline, Structure from Motion techniques can be used to create a scaled 3D model of a bench. This can then be analyzed to provide operators with borehole locations an

An approach to quantitatively determine patient surface contours as part of an augmented reality (AR) system for patient position and posture correction was developed. Quantitative evaluation of the accuracy of patient positioning and posture correction requires the knowledge of coordinates of the patient contour. The system developed uses the surface contours from the planning CT data as the reference surface coordinates. The corresponding reference point cloud is displayed on screen to enable AR assisted patient positioning. A 3D computer vision system using structured light then captures t

Resumen

Given a single image taken from any popular digital camera, how can an object from the scene be reconstructed, or "grabbed", from the picture as a three-dimensional (3D) object? We humans do it effortlessly! This thesis explores how to give computers such a 3D perception. We study how to efficiently represent 3D objects to allow them to be reconstructed from an image. This is challenging as there might exist different shapes that have similar 2D projection. To constrain this ill-posed problem, we propose novel methods to encode the object's geometry and to reconstruct them by relying on 3D pri

As the requirement for more realistic 3D environments is pushed forward by the computer {graphics | movie | simulation | games} industry, attention turns away from the creation of purely synthetic, artist derived environments towards the use of real world captures from the 3D world in which we live. However, common 3D acquisition techniques, such as laser scanning and stereo capture, are realistically only 2.5D in nature - such that the backs and occluded portions of objects cannot be realised from a single uni-directional viewpoint.

Resumen

3D face modeling is currently a popular area in Computer Graphics and Computer Vision. Many techniques have been introduced for this purpose, such as using one or more cameras, 3D scanners, and many other systems of sophisticated hardware with related software. But the main goal is to find a good balance between visual reality and the cost of the system. In this thesis, reconstruction of a 3D human face from a pair of stereo cameras is studied. Unlike many other systems, facial feature points are obtained automatically from two photographs with the help of a dot pattern projected on the object

Resumen

Bayesian methods provide a principled approach to some of the hardest problems in computer vision—low signal-to-noise ratios, ill-posed problems, and problems with missing data. This dissertation applies Bayesian modeling to infer multidimensional continuous manifolds (e.g., curves, surfaces) from image data using Gaussian process priors. Gaussian processes are ideal priors in this setting, providing a stochastic model over continuous functions while permitting efficient inference. We begin by introducing a formal mathematical representation of branch curvilinear structures called a curve tree

A hyperspectral image (HSI) consists of band images that capture the response from numerous light wavelengths in the electromagnetic spectrum. Therefore, HSI has a higher spectral resolution than RGB and grayscale images, which gives HSI enhanced characteristics that are useful in solving various real-world problems. In particular, hyperspectral imaging has been used for analysis and interpretation of material-specific properties in an image. Traditionally, most of the research on this topic has focused on the remote sensing. With the development of sensor technology, HSI has been introduced t

Cette thèse s'intéresse à la reconstruction 3D par stéréophotométrie et à la vision omnidirectionnelle. La stéréophotométrie repose sur l'exploitation de plusieurs photographies d'une scène, capturées sous différents éclairages par un même appareil immobile. La vision omnidirectionnelle rassemble les capteurs ainsi que les assemblages de caméras qui permettent de faire l'acquisition en une image d'une très grande portion de l'environnement autour de l'appareil. En s'appuyant sur quatre décennies de travaux en stéréophotométrie et en utilisant le modèle unifié pour la projection centrale, nous

Resumen

Abstract Three-dimensional scene reconstruction has been an important area of research for many decades. It has a myriad of applications ranging from entertainment to medicine. This thesis explores the 3D reconstruction pipeline and proposes novel methods to improve many of the steps necessary to achieve a high quality reconstruction. It proposes novel methods in the areas of depth sensor calibration, simultaneous localization and mapping, depth map inpainting, point cloud simplification, and free-viewpoint rendering. Geometric camera calibration is necessary in every 3D reconstruction pipelin

Resumen

Les aquifères karstiques, formations géologiques principalement calcaires, représentent un enjeu considérable dans le contexte actuel où de nombreuses régions du monde sont en stress hydrique en raison du changement climatique. Bien que ces aquifères soient l'une des principales sources d'eau douce du monde, ils sont encore sous-exploités à cause du manque de connaissances précises de leur géomorphologie. Les explorer pour collecter des données est une tâche complexe car les réseaux formés dans ce type d'environnement sont très étendus. De plus, l'envoi de plongeurs n'est pas idéal car ils son

Resumen

This dissertation intends to provide theoretical and practical contributions on the development of deep learning algorithms for autonomous driving applications. The research is motivated by the need of deep neural networks (DNNs) to get a full understanding of the surrounding area and to be executed on real driving scenarios with real vehicles equipped with specific hardware, such as memory constrained (DSP or GPU platforms) or multiple optical sensors, which constraints the algorithm's development forcing the designed deep networks to be accurate, with minimum number of operations and low

Resumen

Specifically equipped and programmed robots are highly successful in controlled industrial environments such as automated production lines. For the transition of robots from such controlled uniform environments to unconstrained household environments with a large range of conditions and variations, a new paradigm is needed to prepare the robots for deployment. Robots need to be able to quickly adapt to their changing environments and learn on their own how to solve their tasks in novel situations. This dissertation focusses on the aspect of learning to predict the success of two-object means-e
