For private enterprises, it has become increasingly important and indispensable to utilize advanced information system. Generally speaking, an introductory process of information system starts with an original planning, which extends to a preparation for “Requirement for Proposal” and testing and finally actual system installation and software maintenance. When the system comes to be installed and...
This study proposes a 3D shape measurement device based on an image scanner. The shape reconstruction method using the image scanner is one of the photometric stereo method which uses multiple parallel light sources, but our proposed method is applied to linear light sources. This method is constructed by several processes. First, we estimate an object shape using four images taken by two groups of...
In this study, we propose a method to estimate 3D shape, color and specular reflections of an object using an image scanner with multiple illuminations. In the first process, we estimate an initial shape of the object. Several scanned images taken by illuminations located on the circumference are used to estimate object shape by the photometric stereo using average images reducing the specular reflection...
This study proposes a method to recover 3D shape, color and specular reflections of an object from images taken by an image scanner which has multiple illuminations. The proposed method is constructed by two processes. First is the initial shape estimation and second is the iterative process to estimate the object shape, color and specular components. In this paper, we propose two methods for the...
In this study, by using the image scanner equipped with multiple illuminations, we proposes a method to estimate 3D shape, color and specular reflections of an object. The proposed method consists of two parts. The first process is the initial shape estimation. This method uses several scanned images taken by illuminations located on the circumference, and estimate object shape by the photometric...
Leaf area index within vegetated surface and its fractional area to a target pixel (fraction of vegetation cover) are two important factors for estimation of cooling potential by green vegetation in the context of mitigating heat island effects. This paper explains a technique to retrieve these two parameters from satellite images utilizing three bands of visible, near-infrared, and shortwave infrared...
