    A multi-sensor integrated head-mounted display setup for augmented reality applications
    (IEEE, 2015) Kermen, Ahmet; Aydın, T.; Ercan, Ali Özer; Erdem, Tanju; Electrical & Electronics Engineering; Computer Science; ERCAN, Ali Özer; ERDEM, Arif Tanju; Kermen, Ahmet
    We present an HMD based AR system comprising visual and inertial sensors. The visual sensor is a camera pair and the inertial sensors consist of an accelerometer and a gyroscope. We discuss the temporal and spatial calibration issues that relate to such a system. We introduce simple yet effective methods for estimating the time lag between the camera and the inertial sensors and for estimating the relative pose between the camera and the inertial sensors. These methods do not require a complicated setup for data collection and involve simple equations to solve. Sample results are presented to demonstrate the visual performance of the system.

    A stereo HMD system with visual and inertial data capture for 3D augmented reality applications
    (2016-01) Kermen, Ahmet; Erdem, Tanju; Erdem, Tanju; Ercan, Ali Özer; Balcısoy, S.; Department of Electrical and Electronics Engineering; Kermen, Ahmet
    Augmented Reality (AR) technology has been considered to have a great potential in many different areas such as medical visualization, manufacturing, entertainment and cultural heritage for enhancing human-computer interaction (HCI) and improving user experience. It has been receiving growing interest by several major companies including Apple, Google, Microsoft and Sony. The main objective of augmented reality applications is to give realistic feeling of immersion with overlaying computer generated virtual scene images over user's view through specialized displays. Seamless blending of virtual scene elements on top of real world elements is one of the main requirements for immersive AR applications and it requires a high-accuracy 3D tracking. This thesis deals with the design and development of an augmented reality (AR) system that is made up of a head-mounted display (HMD) unit, visual and inertial sensors. A camera pair is employed as the visual sensor, and the inertial sensor (IMU) unit houses an accelerometer and a gyroscope. The system tries to improve the accuracy of tracking by combining measurement data from visual sensors (cameras) with inertial sensors (accelerometer, and gyroscope). The main objective of this work is the development of a stereo HMD system with visual and inertial data capture for 3D augmented reality applications. The work reported in this thesis was supported by The Scientific and Technological Research Council of Turkey (TÜBİTAK) under the project numbered EEEAG-110E053, which is developed in Özyeğin University.
