When a disaster occurs, we must grasp and evaluate its damage as soon as possible. Then we try to estimate them from some kind of photographs, such as surveillance camera imagery, satellite imagery, p...
As digital photogrammetric system developed, we became able to measure three-dimensional objects on a generic personal computer. And recently aerial photograph is easily obtained, for example we can g...
Image-based measurement systems have been used in various surveying applications for several years. Unfortunately, most of such systems required artificial targets defining object points. ...
A convenient 3D measurement using amateur digital cameras is enormously expected in various fields with appearance of the highresolution amateur digital cameras. In these circumstances, software for ...
A convenient 3D measurement using amateur digital cameras is enormously expected in various fields with appearance of the highresolution amateur digital cameras. In these circumstances, software for ...
Previously, we developed a real time 3-D measurement system based on slit-ray projection method, which enables us to obtain serial range images at 1/30 seconds per scene with an error within ±0.3%. I...
In thermal transformation processes for the production of metal parts of complex shape, shaping tools are frequently used. In die forging as an example, the tools are exposed to high mechanical and ...
We have developed a new type of 3D measurement system which enabled us to obtain successive 3D range data at video rate with an error within ±0.3%In this paper, we try to reconstruct realistic colored...
This paper presents a newly developed high speed 3-D measurement system, which enable us to obtain continuously range image of 768x480 spatial resolution at video rate. It is based on a light pattern ...
We developed ortho-projection and drawing system for reduction of record work of archeological artifacts. But, in this system, there are lacks of data. They were caused by position of source-light (ph...
Measuring of railway structure clearances is a very practical issue, and the operation itself is performed all over the world using various measuring systems. The measurement is aimed chiefly at det...
