An Ultrafast Multi-object Zooming System Based on Low-latency Stereo Correspondence

IROS 2024poster

In this paper, we develop a multiple-object zooming system which can capture clear images of different objects at an ultrafast speed. The system consists of a panoramic HFR stereo camera and a galvanometer-based reflective pan-tilt-zoom (PTZ) camera. In order to alleviate the impact of brightness, n…

Dynamic-Range Focal Sweep: Seamless Continuous Autofocus Based on High-Speed Vision for Magnified Object Tracking

IROS 2024poster

This paper presents an innovative continuous autofocus (C-AF) approach based on high-speed vision. It consistently provides focused images with stable and sufficiently high frame rates, aiming to improve the ability to track small, fast-moving objects in a highly magnified scene. To achieve this, we…

A Flexible Calibration Algorithm for High-speed Bionic Vision System based on Galvanometer

IROS 2022poster

Traditional gimbal-based bionic eye systems usually use a multi-degree-of-freedom mechanical platform to move the camera freely, which makes the structure complex and bulky. The galvanometer-based reflective bionic eye system uses a galvanometer to replace the traditional mechanical rotation structu…

A 500-Fps Pan-Tilt Tracking System With Deep-Learning-Based Object Detection

RA-L 2021

In this letter, we propose a fast mirror-drive pan-tilt target tracking system that can robustly track an object whose appearance varies in a complex background at 500 fps. By assuming a small image displacement between frames, which is a property of high-frame rate vision, we develop an fast object

High-Speed Well-Focused Image-Capturing System for Moving Micro-Objects Based on Histograms of the Luminance

ICRA 2018poster

In recent years, vision-based analysis systems of micro-objects in a microchannel have been actively developed. However, it is difficult to focus on high-speed micro-objects in a microchannel because the general height of a microchannel is approximately 10-100 μm, whereas the depth of focus of the o…

Development of a 4-joint 3-DOF robotic arm with anti-reaction force mechanism for a multicopter

IROS 2017poster

In this paper, we propose a design method for the mechanism of a robotic arm suitable for a multicopter. The motion of an arm attached to a multicopter can possibly disturb the multicopter attitude. Our aim is to suppress this attitude disturbance by mechanical methods. In the proposed design method…

View expansion system for microscope photography based on viewpoint movement using Galvano mirror

IROS 2017poster

Recent progress in LOC technology have made it possible to analyze cells in microfluidic devices in a microscopic environment. Vision-based cell analysis systems have a limitation in their analysis range owing to the small view area of the microscopic objective lens; thus, an expansion of the view a…

Control scheme of nongrasping manipulation based on virtual connecting constraint

ICRA 2016

The research field of nongrasping manipulation is a maturing area in robotic motion control. However, the common principles of motion planning for nongrasping manipulation systems have not yet been established. This paper proposes the concept of virtual connecting manipulation as a generalized motio

A scheme for manipulating a passive object using an active plate

ICRA 2015poster

We propose a novel scheme for manipulating a passive object using an active plate. The objective of this study is to control an object's orientation with respect to the gravitational force direction by using an active plate for realizing hitherto unrealized object motion. In this context, motions of…
