This paper proposes a novel notion of Epipolar Plane Range Image (EPRI). A line-scanning laser range sensor is mounted on the side of our data acquisition vehicle, repeating drawing horizontal scanning lines. Laminating the line range data along time axis, we can follow temporal continuity of horizontal cross section of the geometry seen from the scanner,(More)
This paper presents a system that fuses data from a vision sensor and a laser sensor for detection and classification. Fusion of a vision sensor and a laser range sensor enables us to obtain 3D information of an object together with its textures, offering high reliability and robustness to outdoor conditions. To evaluate the performance of the system, it is(More)
We present to generate a bird’s-eye view of road traffic scene by integrating multiple images from in-vehicle cameras for supporting traffic safety. There are many blind spots at an intersection. Such blind spots will cause accidents and traffic jams. If it is possible to obtain views from multiple vehicles coming into one intersection from different(More)
Abstract— The estimation of a 3D shape of a scene as well as the position and the orientation of the sensor has been extensively researched, especially for Virtual Reality (VR) and Robotics systems. To achieve this estimation, a system that consists of a laser range sensor, Global Positioning System (GPS), and Gyro sensor has been proposed, actually(More)
Precise and accurate 3D model of a road structure is basic information that can be utilized for various purposes, such as safety measures, driving simulation, and reference data for autonomous driving. Generally, the 3D model of a tunnel has been constructed using gyro sensor, however, error accumulation becomes a considerable problem in the case of long(More)
In this paper, we propose a novel type of 3D scanning system named 'climbing sensor'. This system has been designed for scanning narrow and vertically stalky spaces, which are hard or extremely inefficient to scan by commercial laser range scanners due to their dimensions and limitation of FOVs. The climbing sensor equips a platform with two line scanners(More)
We propose a novel analysis of space-time volume of spherical projection image. So far, space-time analyses have been extensively conducted for various purposes, i.e. 3-D reconstruction, estimation of camera motion and novel view synthesis and most of them consider only a planer projection and a single camera. In contrast, we conducted analysis on spherical(More)
Modern 3D digital archiving technique provides a reliable assistance to archaeologists. In this paper, we explore a novel framework for digital classical sculpture comparison. Quantitative comparison is introduced, and shape difference is visualized as an indicator to infer unclear points about statue reproduction process in Roman period. Providing a new(More)
3D shape comparison with digital copies draws increasing attention in modern culture heritage studies. In this paper, we focus on analyzing portrait sculptures of Augustus with 3D scanned data. A feasible framework of automatic object categorization is proposed based on shape comparison, where distinguishing regions are simultaneously detected as well. High(More)
