Mobile robots suffer from sensory data corruption due to body oscillations and disturbances. In particular, information loss on images captured with onboard cameras can be very high, and such loss may become irreversible or computationally costly to undo. In this paper, we propose a novel method to minimize average motion blur captured by such mobile visual sensors. To this end, we derive a motion blur metric (MMBM) that can be computed in real-time by using only inertial sensor measurements and validate it through comparisons with optic flow computations. The applicability of MMBM is illustrated through a motion blur minimizing system implemented on the SensoRHex hexapod robot by externally triggering an onboard camera based on MMBM values computed in real-time while the robot is walking straight on a flat surface. The resulting motion blur is compared to motion blur levels obtained with a regular, fixed frame-rate image acquisition schedule by both qualitative inspection and using a blind blur metric on captured images. MMBM based motion blur minimization system not only reduces average motion blur, but also avoids frames with extreme motion blur before an image gets corrupted by appropriately delaying the triggering of frame acquisition.

A Real-Time Inertial Motion Blur Metric: Application to Frame Triggering Based Motion Blur Minimization

A Novel real-time inertial motion blur metric with applications to motion blur compensation /
Mutlu, Mehmet; Saranlı, Afşar; Saranlı, Uluç; Department of Electrical and Electronics Engineering (2014)
Mobile robots suffer from sensory data corruption due to body oscillations and motion disturbances. In particular, information loss in images captured with on board cameras can be very high, may become irreversible or computationally costly to compensate. In this thesis, a novel method to minimize average motion blur captured by such mobile visual sensors is proposed. To this end, an inertial sensor data based motion blur metric, MMBM, is derived. The metric can be computed in real time. Its accuracy is val...
A comparative evaluation of adaptive and non-adaptive Sliding Mode, LQR & PID control for platform stabilization
Akgul, Emre; Mutlu, Mehmet; Saranlı, Afşar; Yazıcıoğlu, Yiğit (2012-12-01)
During the uniform locomotion of compliant legged robots and other terrain vehicles, the body of the robot often exhibits complex oscillations which may have a disturbing effect on onboard sensors. For a camera mounted on such a robot, due to perspective projection, the effects of angular disturbances are particularly pronounced as compared to translational disturbances. This paper is motivated by the particular problem of legged robots exhibiting angular body motions and attempts to evaluate the performanc...
OUTDOOR LOCALIZATION OF A ROBOTIC PLATFORM USING PANAROMIC IMAGES
Ekinci, Gülçin Ceren; Koku, Ahmet Buğra; Department of Mechanical Engineering (2021-7-8)
Advances in robotics liberated robots from factory floors by the end of 20th century. Use of robots in our daily lives is only expected to increase in time. Robots, while relieving us from the burden of tedious, hard and dangerous tasks, most of them are still expected to be territorial, i.e. they will operate in a predefined or rather bounded environment. For enhanced performance, a robot should be familiar with its territory. In this work, use of skylines extracted from panoramic images is studied in orde...
Multi-Frame motion deblurring of video using the natural oscillatory motion of dexterous legged robots
Gultekin, Gokhan Koray; Saranlı, Afşar (2019-07-18)
Motion blur is a common problem for machine vision applications in legged mobile robotic platforms. Due to the oscillatory walking nature of these platforms, the cameras on them experience disturbances so that most of the captured frames are motion blurred. Motion blur results in loss of information in individual image frames and therefore makes single-frame deblurring an ill-posed problem. The variation in the magnitude of motion blur in consecutive video frames can be exploited to better restore these fra...
