A method is presented for generating a bird's-eye view of a road traffic scene via the integration of multiple images from in-vehicle cameras; the resulting bird's-eye view supports the goal of greater traffic safety. As there are typically many blind spots at any given intersection which could lead to accidents or traffic jams, if views can be obtained(More)
— 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 constructed,(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)
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)
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)
Auguste Rodin is the most celebrated sculptor of the 19th century. His works, such as The Gates of Hell, The Thinker, and The Burghers of Calais, are famous worldwide. To our knowledge, no art historians have analyzed three-dimensional data of Rodin's work. This paper describes our project to fill this need by digitally archiving the bronze statue, The(More)
This paper proposes a novel notion of spatio-temporal range image and an efficient way to construct 3D geometric model of urban scene with the use of this range image. We mount vertical and horizontal line-scanning laser range finders on our vehicle. The vertical one is for acquiring the scene geometry itself, and the horizontal one is for self-positioning(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)
Computer modeling of a large-scale scene such as a city becomes an important topic for computer vision and computer graphics research areas etc. Image-based rendering (IBR) is an effective method for expressing realistic scene, and can construct any arbitrary viewpoint by using the captured real images. However, the large size of the image database in IBR(More)
