    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»

    This paper presents a new approach based on light striping for reconstructing a 3D model from a real object. The proposed system consists of a light plane projector, camera and cube frame with LEDs attached. As in other light striping systems, the correspondence problem is solved by projecting light plane onto an object inside a frame. However, we use only cross-ratios and vanishing points to set ...

    Laser range scanners are a popular method for acquiring three-dimensional geometry due to their accuracy and robustness. Maximizing scanner accuracy while minimizing engineering costs is a key challenge to future scanner designs. Engineering costs arise from both expensive components and difficult calibration requirements. We propose a two camera range scanner design, specifically chosen to minimi... 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»

    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»

    A novel solution is presented to the Nearest Neighbor Problem that is specifically tailored for determining correspondences within the Iterative Closest Point Algorithm. The reference point set P is preprocessed by calculating for each point p&oarr;i∈P that neighborhood of points which lie within a certain distance ε of p&oarr;i. The points within each ε-neighb...

  • 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»

    An algorithm for the automatic construction of a 3D model of archaeological vessels is presented. In archeology the determination of the exact volume of arbitrary vessels is of importance since this provides information about the manufacturer and the usage of the vessel. To acquire the shape of objects with handles in 3d is complicated, since occlusions of the object's surface are introduced by th... View full abstract»

    Due to its portability and great maneuverability, a handheld range sensor is a flexible solution or complement to efficiently digitize the 3-D shape for a wide variety of objects. This paper firstly presents a review of the existing hand-held technologies. Although the designation encompasses various system configurations, the structured light pattern, if any and sensor positioning are key element... 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»

  • Generation of geometric model by registration and integration of multiple range images

    We propose a method to construct a 3-D geometric shape model by registering and integrating multiple range images under a unified framework. We use 3-D points around the object surface as the correspondence key, because the closest data point from an arbitrary 3-D point should be matched if the data are registered correctly with some exceptional cases. We assume that the input shapes are roughly r... 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»

    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 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»

    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»

    In this paper we present a new sensor that can measure on-line the material wear in laser material processing. To meet the demands of industrial production optical rough surfaces have to be measured at low apertures within the rough environment generated by the production process. Hence, common sensors have a quite poor performance. It is hardly possible to measure the material wear through the pl... 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»

    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 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»
