    We introduce a novel outlook on the self-calibration task, by considering images taken by a camera in motion, allowing for zooming and focusing. Apart from the complex relationship between the lens control settings and the intrinsic camera parameters, a prior off-line calibration allows to neglect the setting of focus, and to fix the principal point and aspect ratio throughout distinct views. Thus... View full abstract»

    Within a project whose objective is to develop a small-size 3D sensor combining a video camera with a 3D laser-based "camera", this paper describes the current status of the laser camera. The prototype of the laser camera is operational and is able to produce 3D "images" with good definition at high speed. Because of size constraints, some of the control electronics are implemented in an FPGA. The... View full abstract»

    The use of a laser range sensor in the 3D digitalization process for inspection tasks allows very significant improvement in acquisition speed and in 3D points density but does not attain the accuracy obtained with a Coordinate Measuring Machine (CMM). Inspection consists in verifying the accuracy of a part related to a given set of tolerances. It is thus necessary that the 3D measurements be more... View full abstract»

    In this paper we propose a physically-based 3D dynamic facial model based on anatomical knowledge for facial expression animation. The facial model incorporates a physically-based approximation to facial skin and a set of anatomically-motivated facial muscles. The skin model is established through the use of a mass-spring system with nonlinear springs which simulate the elastic dynamics of a real ... View full abstract»

    Subdivision schemes are commonly used to obtain dense or smooth data representations from sparse discrete data. e.g., B-splines are smooth curves or surfaces that can be constructed by infinite subdivision of a polyline or polygon mesh of control points. New vertices are computed by linear combinations of the initial control points. We present a new non-linear subdivision scheme for the refinement... View full abstract»

    This paper presents a method of computing camera positions from a sequence of overlapping images obtained from a binocular/trinocular camera head. First, we find matching features among the images at each camera head position. Because the individual cameras are calibrated we can directly compute the 3D coordinates of these features using triangulation. Then we find matching features across adjacen... View full abstract»

    Building 3D models of real-world objects by assembling views taken by a range sensor promises to be a more efficient method than manually producing CAD drawings. In this technique, a series of range images are acquired and then registered or aligned with each other to a high degree of accuracy. Finally, the polygonal meshes corresponding to the range images are merged to form a complete 3D model c... View full abstract»

    The view planning problem, also known as the next-best-view (NBV) problem, for object reconstruction and inspection, has been shown to be isomorphic to the set covering problem which is NP-Complete. In this paper we express a theoretical framework for the NBV problem as an integer programming problem including a registration constraint. Experimental view planning results using a modified greedy se... View full abstract»

    The shape representation and modeling based on implicit functions have received considerable attention in computer vision literature. In this paper, we propose extended hyperquadrics, as a generalization of hyperquadrics developed by Hanson, for modeling global geometric shapes. The extended hyperquadrics can strengthen the representation power of hyperquadrics, especially for the object with conc... View full abstract»

    The technique of 3-dimensional (3D) reconstruction from two orthogonal images is mainly used in ventricle or vessel reconstruction. In the literature, the 3D object is considered to be a stacked 2-dimensional (2D) slice set and 3D reconstruction can be achieved by constructing a stack of 2D slice reconstructions, by rendering each slice into two 1-dimensional profiles corresponding to a pair of ro...

    This paper presents an overview of our efforts in modeling-from-realty to create virtual reality models through observation of real objects. These efforts span three aspects: how to create geometric models of virtual objects; how to create photometric models of virtual objects; and how to integrate such virtual objects with real scenes. For geometric model creation, we have developed a two-step me... View full abstract»

    In this paper we propose a robust method for recognition and pose determination of 3-D objects using range images in the eigenspace approach. Instead of computing the coefficients by a projection of the data onto the eigenimages, we determine the coefficients by solving a set of linear equations in a robust manner. The method efficiently overcomes the problem of missing pixels, noise and occlusion... View full abstract»

    In this research, a novel method of reconstructing 3D urban scene using vehicle-borne laser range scanners is proposed. Two one-dimensional laser range scanners are mounted on the roof of a vehicle, doing horizontal and vertical profiling respectively. As the vehicle moves ahead, a horizontal and vertical range profile of the surroundings is captured at each odometer trigger. The freedom of vehicl... View full abstract»

  • Structure and motion from two uncalibrated views using points on planes

    This paper is about the problem of structure and motion recovery from two views of a rigid scene. Especially, we deal with the case of scenes containing planes, i.e. there are sets of coplanar points. Coplanarity is a strong constraint for both structure recovery and motion estimation. Most existing works do only exploit one of the two aspects, or, if both, then in a sub-optimal manner. A typical ... View full abstract»

    Analysis and reconstruction of range images usually focuses on complex objects completely contained in the field of view; little attention has been devoted so far to the reconstruction of partially occluded simple-shaped wide areas like parts of a wall hidden behind furniture pieces in an indoor range image. The work in this paper is aimed at such reconstruction. First of all the range image is pa... View full abstract»

    Optical 3-D sensors are used as tools for reverse engineering and virtual reality to digitize the surface of real three-dimensional objects. We discuss an almost fully automatic method to generate a surface description based on a mesh of curved or flat triangles. The method includes mesh reduction, smoothing, and reconstruction of missing data. The generated meshes feature minimum curvature variat... View full abstract»

    Registration of range images requires the identification of common portions of surfaces between which a distance minimization is performed. This paper proposes a framework for the use of dense attributes of range image elements as a matching constraint in the registration. These attributes are chosen to be invariant to rigid transformations, so that their value is similar in different views of the... View full abstract»

    This paper presents an algorithm for extracting planar patches by integrating both intensity and range data provided by a stereo system. For dealing with noisy and sparse range data, the initial segmentation is based on intensity information, and then the resulted regions are thresholded using depth data. This new algorithm, different from the existing ones that use only range data in the segmenta... View full abstract»

    Capturing range data for every pixel within an image has the potential for a wide array of new imaging applications. While there are many approaches to accomplishing this goal, one that has been the subject of current research and advanced development is the so-called scannerless range imaging system (SRI) that is based upon an innovation by M.W. Scott (1990) from Sandia National Laboratories. Whi... View full abstract»

    In this paper, we present a method for automatically creating a 3D model of a scene from a set of range images obtained from unknown viewpoints. Existing 3D modeling approaches require manual interaction or rely on mechanical methods to estimate the viewpoints. Given a set of range images (views), we use a surface matching system to exhaustively register all pairs of views. The results are verifie... View full abstract»
