JAMSTEC has been developing two-type autonomous underwater vehicles (AUVs): a cruising AUV and a working AUV, since last October. These vehicles will perform carbon dioxide (CO2) observations and hydrothermal plume exploration up to depth of 3,000 meters. The cruising AUV (about 4 m long, 2 tons in weight) is equipped with three major observation devices: a multi-beam echo sounder, side-scan sonar,...
Multi-view video consists of multiple views which are taken by multiple cameras from different positions and angles. It allows the users to freely change their viewpoints. Typical applications of multi-view video include Free Viewpoint TV, remote medical surgery, wireless multimedia sensor networks and so on. However, the traffic of multi-view video is also several times larger than traditional multimedia,...
Recently, multi-view video that is taken by multiple cameras from different positions and angles to provide the real world experience has attracted more attentions. Its typical applications include Free Viewpoint TV, remote medical surgery, wireless multimedia sensor networks and so on. The size of multi-view video is several times bigger than traditional multimedia, which brings much more increment...
A reconfigurable master device has been proposed for a reconfigurable modular surgical robot. A simulation-based experimental setup was developed to evaluate the feasibility of the master device. The time spent to perform a given task, the workload evaluated by the NASA TLX questionnaire, and the preference of the topology indicated by the subjects were used as evaluation items. The preliminary results...
We previously proposed a model for a handshake approaching motion with a voice greeting and developed a handshake robot system that applied the proposed model for embodied interaction with humans. The handshake robot system was fabricated by considering the average size of a human arm. However, small-size embodied interaction robots are required for use in homes. Therefore, in this study, a small-size...
The aim of our project is to develop a robot to manipulate an object in human environment. In this paper, as a first step, we focus on opening paper box such as tea box, and present a method to plan grasp motion by 2 arms with multi-fingered hands. we propose a task priority based scheme to plan grasping area consistent with whole steps of the given task procedure. Based on the grasping area and the...
Pedestrian detection is a difficult task for the following reasons. Firstly, pedestrians have many variations of size, pose, clothing, and motion. Secondly, the background tends to be crowded. Thirdly, many pedestrian-like patterns are observed in real environments. As a result, even if state-of-the-art pattern recognition method is used, a frame-by-frame detection has many false positives and negatives...
In MPEG standards, motion compensation is used for inter-frame compression. Motion compensation generates motion vectors in order to predict the current frame regions from previously decoded frames. These motion vectors represent motion information between regions in different frames and are useful in motion analysis. However, the motion vectors of homogeneous, low-textured, and line regions tend...
It is very important to guarantee the quality of the industrial products by means of visual inspection. In order to reduce the soldering defect with terminal deformation and terminal burr in the manufacturing process, this paper proposes a 3D visual inspection system based on a stereo vision with single camera. It is technically noted that the base line of this single camera stereo was precisely calibrated...
Recently, many humanoid robots can be formed on television programs and public events. In this paper, we pay attention to such robots. Under this background, diverse parts have been developed and many symposiums have been held to share domain knowledge with many engineers. Furthermore, as for the robot technology, we think that a robot which makes humanlike movement and general view has been developed...
