Estimation of 4-DoF manipulator optimal configuration for autonomous camera calibration of a mobile robot using on-board templates
Ch. 9438925.
Camera calibration is one of the important tasks in the field of robotics and computer vision. It enables to increase the accuracy of metric measurements in photogrammetry applications and provides higher performance in computer vision algorithms such as stereo matching and motion estimation. It is known that regardless of the calibration method used variation of given estimated camera parameters their is inevitable due to multiple reasons: varying weather conditions, temperature fluctuations or severe operation mode of a robotic system. In order to alleviate the aforementioned issues recalibration is required. In this work we employed 4-DoF manipulator Servosila Engineer mobile robotic system equipped with an on-board camera. In order to automate the process of calibration an algorithm is developed which enables to estimate optimal manipulator joint configurations. Forward kinematics is solved on a discretized set of joint angles, subsequently estimating possible camera positions for its further calibration. Experiments on real robot demonstrate the possibility of usage of the developed algorithm to find optimal joint configurations for automatic camera calibration.

Digital human models (DHM) for virtual environments allow a cost-effective and reproducible evaluation of computer vision algorithms that are employed in robotics, e.g., human detection, tracking and following. Yet, many popular robotics simulators do not achieve a reasonable level of realism and diversity required to rigorously test such algorithms under varying conditions. This paper introduces ...

This study presents on-the-fly identification and multi-step prediction of nonlinear systems with delayed inputs using a dynamic neural network combined with a smooth projection onto ellipsoids. The projection enforces parameter constraints that guarantee stability, while a Lyapunov–Krasovskii analysis yields computable ultimate error bounds. Riccati-type matrix inequalities are derived, providing an efficient vectorization–projection–devectorization implementation suitable for ...

In this work, we propose a ratio-dependent intraguild predation model that incorporates fear and gestation delay. Further, the cost of the intraguild predator's fear is thought to decrease the size of the intraguild prey. The interaction between prey and predator takes place in the form ratio-dependence type. This type of functional response offers a valuable ...

Fear and prey refuges are two significant topics in the ecological community because they are closely associated with the connectivity of natural resources. The effect of fear on prey populations and prey refuges (proportional to both the prey and predator) is investigated in the nonlinear-type predator-harvested Leslie–Gower model. This type of prey refuge is much ...
