Questions tagged [motion-detection]

Related to detection of motion related to programming issues, like computer vision, sensor control, etc.

Motion detection is a process of confirming a change in position of an object relative to its surroundings or the change in the surroundings relative to an object. This detection can be achieved by both mechanical and electronic methods. In addition to discrete, on or off motion detection, it can also consist of magnitude detection that can measure and quantify the strength or speed of this motion or the object that created it.

Motion can be detected by: sound (acoustic sensors), opacity (optical and infrared sensors and video image processors), geomagnetism (magnetic sensors, magnetometers), reflection of transmitted energy (infrared laser radar, ultrasonic sensors, and microwave radar sensors), electromagnetic induction (inductive-loop detectors), and vibration (triboelectric, seismic, and inertia-switch sensors).

Frame Difference for non static camera

I am trying to detect motion in a video taken by non-static camera in this case UAV. what I planned to do is to remove the camera motion effect by aligning the frames as much as they overlap then make simple differencing, Here what I did - I used…

Picamera - Optimized way to do motion detection

The Picamera documentation provides examples on how one would go about implementing motion detection, without the actual motion detection algorithm itself. Although I am sure there are many more, I have thought about three ways of doing the motion…

Network Protocol and Listening Port Number with Unity3D and Matlab

I can stream motion capture data live from Xsens MVN Studio into Unity3D and animate a character with it in real-time, because the Unity3D character listens to port number 9763 of the same machine and receives the motion data from there, which means…
