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).

Best way to retrofit existing alarm PIR with esp8266/etc?

Without going into too much detail: Hardware : Alarm System : Risco Lightsys2. Nothing unique here, each PIR (and sensor, door contacts, etc) gets 1.5 terminals on the motherboard / "zone expander" (the mobo only allows for 8 devices). 3 terminals…

create a video analysis software in java

I want to create a program that would take a video of a baseball being thrown indoor into a net and analysis the movement and angle to calculate how far the ball would have gone. This is my final goal and is a long way away, as I do not know how to…

Python to simulate keyboard strokes

Could i take a motion sensor that is attached to the raspberry pi (running Raspbian) that when the sensor is tripped that it would send a keyboard stoke. i am hoping that the keyboard stroke would control a application. looking for this to be done…

Is there any C++ opencv code to compute velocity of key feature points in each frame of video?

I would like to compute velocity of key feature points and set thresholding for motion detection in a video. I have a python code with me as follows: def compute_vel_kf(self, fps): if ((len(self.features) == 0) or (self.features == None)): …
