A lot of plumbings exist in factories and so on. It is difficult for humans to inspect them directly. Therefore, automated inspection by robots is desirable. However, many of existing inspection robots have to rotate the camera because a conventional camera can see only one direction while a piping has a cylindrical geometry. The use of an omni-directional camera is effective for the solution o...
This investigation examined the validity of newly developed Adult OMNI Elliptical Ergometer Ratings of Perceived Exertion Scales. 60 men and women performed a graded exercise test on an elliptical ergometer. Oxygen consumption (VO2), heart rate (HR), and ratings of perceived exertion were recorded at each stage from the Borg 15 Category scale and two different OMNI scales. One scale employed an...
This dissertation describes the implementation of an omni-directional vision system as sole sensor for a robot building a topological map of an indoor environment, using the Spatial Semantic Hierarchy created by Benjamin Kuipers [Kuipers 00]. So far, no attempt to implement the SSH using a vision sensor has been made. We will show that an omni-directional vision system is a good sensor for the ...
A unified approach to unwarping of omni-images into panoramic or perspective-view images is proposed. The approach does not adopt the conventional technique of calibrating the related parameters of an omni-camera. Instead, it is based on a new concept of a pano-mapping table, which is created once forever, by a simple learning process for an omni-camera of any kind, as a summary of the informat...
In this paper, we describe a new Telepresence system which enables a user to look around a virtualized real world easily in network environments. The proposed system includes omni-directional video viewers on web browsers and allows the user to look around the omni-directional video contents on the web browsers. The omni-directional video viewer is implemented as an Active-X program so that the...
Wireless Sensor Networks (WSNs) incorporate smart antennas for information propagation to offer connected coverage with reduced interference. This paper presents an omni directional antenna assisted scheme for WSNs to reduce network redundancy besides offering connected coverage. The directivity of an omni directional antenna outfitted on a sink node is exploited to reduce network redundancy an...
Structure From Motion Using Omni-directional Vision and Certainty Grids. (August 2004) Steven Rey Ortiz, B.S., Texas A&M University Chair of Advisory Committee: Dr. Ricardo Gutierrez-Osuna This thesis describes a method to create local maps from an omni-directional vision system (ODVS) mounted on a mobile robot. Range finding is performed by a structure-from-motion method, which recovers the th...
Due to their advantages, omni-directional mobile robots have found many applications especially in robotic soccer competitions. Despite recent advances, effective control and self-localization of omni-directional mobile robots remain as important and challenging issues. In this work, a practical approach for control and self-localization of an omni-directional robot is proposed. For this purpos...
BACKGROUND AND STUDY AIMS Olympus recently developed a new algorithm called Omni mode that discards redundant video capsule endoscopy (VCE) images. The current study aimed to demonstrate the non-inferiority of the Omni mode in terms of true positives (TPs) and the superiority of the Omni mode with regard to reading time against a control (ordinary ES-10 system). PATIENTS AND METHODS This mult...
THE PURPOSE OF THE STUDY WAS 1) to determine the intensity of an indoor cycling session; 2) to know the correlation between the rating of perceived exertion (RPE) scales (Borg and OMNI) and % heart rate reserve (%HRR) with categories; and 3) to evaluate the validity of RPE scales (Borg and OMNI) with respect to the heart rate (HR) and %HRR. A total of fifty-three subjects, 25 males and 28 femal...
