3D Sensing systems mounted on mobile platform are emerging and have been developed for various applications. In this paper, we propose a profiler scanning system mounted on a rover to scan and reconstruct a bas-relief with high density and accuracy. Our hardware system consists of an omnidirectional camera and a 3D laser scanner. Our method selects good projection points for tracking to estimate motion...
This research develops a robotic vision and manipulation technologies for random bin-picking. Especially, we focus on the manipulation technology where a dual-arm manipulator first picks up an object from the pile, then regrasps it from the right hand to the left hand, and finally places it to the fixture. We first explain an overview of our research project. Then, we explain about the grasp/manipulation...
Laser range sensors are often demanded to mount on a moving platform for achieving the good efficiency of 3D reconstruction. However, such moving systems often suffer from the difficulty of matching the distorted range scans. In this paper, we propose novel 3D features which can be robustly extracted and matched even for the distorted 3D surface captured by a moving system. Our feature extraction...
We are researching ways to support network operators with environments that allow them to perform their jobs more efficiently. Currently the introduction and migration of new network systems are becoming more difficult because a lot of network systems interact with each other. We have been seeking technologies to support operators without changing the existing network system environments. In our last...
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 coincidence between our result and previous...
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 perspective for the culture relics study, our...
The behavior of a GUI object in a multi-window application often depends on GUI objects in the same window and other windows. To confirm correct behavior under all GUI appearances is essential to ensure software acceptance and remains a challenging problem. We propose an algorithm which exercises each GUI object at least once in all GUI appearances as captured by running the application under test...
We propose an interactive annotation system that allows users to obtain operational knowledge from annotations that are automatically drawn on top of specific Operation Support System (OSS) windows. Currently it is difficult for OSS users to share knowledge because they lack efficient tools to express and share the knowledge. Our proposal rectifies this omission by allowing users to create, update...
A current state of an Operation Support System (OSS) is very important for realizing an advanced integrated operation support in network management and operation business using OSSs. Appropriate recognition of a current state allows improvement of business operation efficiency and security. In practical deployment environments, each OSS is implemented by each set of technologies, and those implementation...
