“…In such a context, the proposed strategy could significantly contribute to the gathering of visual evidence against criminal acts or reinforce the border control mechanisms [ 32 , 33 , 34 , 35 ]. Covert military operations have been already mentioned, but homeland security missions, securing areas, convoy protection [ 36 ], etc., could also benefit from this approach; in sporting events [ 37 , 38 ], where the goal is to simultaneously follow several targets of interest, while minimizing intrusion in the scene; cinematographic and audiovisual works [ 39 , 40 ], with the intent of simultaneously shooting several points of view from the same trajectory in the air; wildlife monitoring, attempting to study animal behavior in relatively open areas [ 41 , 42 ], with minimal intrusion into the environment; and in traffic surveillance applications, enabling simultaneous tracking and close-up filming of the behavior of several vehicles [ 43 , 44 ].…”

In this paper, we aim to open up new perspectives in the field of autonomous aerial surveillance and target tracking systems, by exploring an alternative that, surprisingly, and to the best of the authors’ knowledge, has not been addressed in that context by the research community thus far. It can be summarized by the following two questions. Under the scope of such applications, what are the implications and possibilities offered by mounting several steerable cameras onboard of each aerial agent? Second, how can optimization algorithms benefit from this new framework, in their attempt to provide more efficient and cost-effective solutions on these areas? The paper presents the idea as an additional degree of freedom to be exploited, which can enable more efficient alternatives in the deployment of such applications. As an initial approach, the problem of the optimal positioning with respect to a set of targets of one single agent, equipped with several onboard tracking cameras with different or variable focal lengths, is addressed. As a consequence of this allowed heterogeneity in focal lengths, the notion of distance needs to be adapted into a notion of optical range, as the agent can trade longer Euclidean distances for correspondingly longer focal lengths. Moreover, the proposed optimization indices try to balance, in an optimal way, the verticality of the viewpoints along with the optical range to the targets. Under these premises, several positioning strategies are proposed and comparatively evaluated.

“…Computer vision uses algorithms to detect identification features in video clips such as patterns or color differences [13]. A computer analysis system requires several cameras to be placed around a sports area, and can require manual input as a calibration of the game event [14]. Meanwhile, developments in the use of computer analysis technology to automate the capture of player movements continue with evaluations developed [15].…”

This study aims to develop an Android-based model of measurement in orthodox shot put styles. The research method used is research and development which adapted from Borg and Gall's theory including the 10 stages of development. The research subjects were 12 males and females athletes. Data collection uses observation, questionnaire, interview, and test. Data analysis technique used in this research is descriptive qualitative and statistics analysis. The result showed the average value of the small-scale trials with 8 subjects of athletic athletes is 82% in the category "Good" which means the android-based shot put gauge is "feasible" to be used as an orthodox shot put style. The average value of large-scale group trial with 12 subjects of athletic athletes is 86,2% also in category "Good" meaning the Android-based shot put is also "feasible" to be used as a gauge for orthodox shot put style. The conclusion from this study is the Android-based in orthodox shot put measurement test instrument which is feasible to be applied to measure the results of shot put. Future research can develop further in sensor system. However, the sensors used in UDM devices use laser sensors.

“…Pose estimation is used in [2] for optimizing the turning velocity of a robot. Unmanned aerial vehicle pose estimation is performed in [3] for live sports production. The three-dimensional model-based tracking of a tennis court is obtained using a monocular camera.Using computer vision in pose estimation is advantageous especially indoors where the global positioning system (GPS) is denied.…”

In this paper, the singularity of Euler angles rotation representation in robot pose estimation is overcome. This is accomplished through coordinate system rotating and signadjusting of the intrinsic parameter camera matrices. A stereo pair is attached to the robot and the extended Kalman filter is used as a recursive pose estimator. An extensive set of synthetic and real experiments have been carried out under various motion patterns in both singular and nonsingular settings. The approach has proved accurate in face of singularity and stable during Jacobian calculations as well.
