Motion Estimation Using Sensors
نویسنده
چکیده
Linear displacement estimation of a mobile device is useful in various real time applications, such as inertial navigation systems, video surveillance, video encoding etc. Present state of the art techniques perform the global motion estimation using image processing techniques, which requires complex computations and more power consumption. Here, an attempt has been made to estimate the linear displacement of a mobile device using the inbuilt sensors. The in-built 3-axis accelerometer of mobile devices is employed to determine the linear displacement. Three different methods are used to convert acceleration to displacement. From the results we conclude that the in-built sensors can be used for linear displacement estimation of mobile devices.

متن کاملGlobal motion estimation from semi-dynamic video using motion sensors
Global Motion Estimation(GME) techniques have been developed and usually applied on video that motion takes place often. Although these methods produce accurate results where frequent motion occurs, they turn out to be inefficient if motion is not so often in the video as in semidynamic videos. In this paper, we propose motion sensors that will indicate the existence of motion and yield quick a...
