In this study, we present a method for all-around depth estimation from multiple omnidirectional images for indoor environments. In particular, we focus on plane-sweeping stereo as the method for depth…
In this study, a gamma irradiation experiment for our proposed bird's-eye view system was conducted. Experimental results show that cameras attached to our system malfunctioned one by one in the…
During the teleoperation of construction machines, it is highly needed to visualize the machine body itself. This is because the operator needs to perform a visual confirmation of the construction…
Bird's-eye view system is one of image presentation systems for teleoperation. Bird's-eye view image helps an operator to visually recognize surrounding environments because of its high visibility. However, when there…
Nowadays, with population aging, shortage of care workers is becoming a serious problem in Japan. Therefore, the introduction of assistive technologies at nursing care sites is a measure expected to…
Spherical cameras, which can acquire all-round information, are effective to estimate rotation for robotic applications. Recently, Convolutional Neural Networks have shown great robustness in solving such regression problems. However they…
Localization is essential for construction machines navigation. Current construction machines use RTK-GNSS for this purpose. We consider that using on-board cameras with SLAM algorithms to estimate machines' ego-motion and position…
In this paper, we propose a novel camera orientation estimation method based on the computation of the vanishing point of water drops in leaking indoor environment. Camera orientation estimation is…
We propose a novel method to simulate image noise caused by gamma-ray irradiation. Monte Carlo simulation is utilized to calculate the interaction between the gamma-ray and the image sensor, and…
In disaster sites, workers may not be allowed entry due to the risk of secondary disasters. Remote operation of construction machines is then necessary for emergency disaster recovery work. For…
