In this paper, an accurate long-distance position measurement system using laser range finders (LRFs), which can be used for surveys in construction fields is proposed. Since the LRF is a sensor which can measure distance to surfaces of objects by radiating laser beams from itself and receiving the reflected ones, data obtained from the LRF are nothing more than the contours of objects. For this reason,...
Intelligent Space (iSpace) is a space which has ubiquitous sensory intelligence. In iSpace, positions of objects inside the space are one of the most basic information to implement various applications. This paper describes a method to localize the target objects using distributed laser range finders. Since data from a laser range finder is only distances and angles to object surfaces, we need to...
The convergence and stability of the level set method depend on the speed function. Therefore, it is important to define the speed function in a manner that is suitable for the individual application. In the present paper, we propose a novel speed function of the level set method for moving object extraction from a video sequence with a stationary background. The speed function focuses on the precision...
Space is a challenging field for science engineering and education. Cosmo Flower 2008 is a payload on the International Space Station coordinated by Japan Manned Space Systems Corporation (JAMSS). Science team, local governments and civilians get together to send flower seeds to space. This mission aims to create a legend of space, which will be shared by everyone. Seeds of plants including Japanese...
Semantic object extraction from a video sequence is an indispensable technique in new content-based applications, such as in the international standards MPEG-4 and MPEG-7. In the present paper, we propose a technique that extracts the shape of moving objects from a video sequence with a stationary background by the level set method. In the proposed method, two concepts are incorporated into a novel...
This brief proposes a process of implementing a teletweezing system using multiple slaves for deformable object manipulation such as bio tweezing tasks. The multiple slave feature is desirable to improve both the manipulation dexterity and stable grasping force control capability. A flexible multiple robot connection environment is assured in a very quick and easy manner using an RT-Middleware platform...
