To implement naive approach using Webcam Capture API only, you will need to change the WebcamMotionDetector source code so it pass lastMotionTimestamp variable into the WebcamMotionEvent - you will need it to calculate time different. If you are looking for other, more advanced solution, you may use features tracking, e.g. Otherwise COG will be calculated incorrectly. 3) When you first time running CamSpliiter it will ask you to choose real webcam.

2) Execute any webcam software and select 'Camsplitter' device as video source.

How to use 1) Download and install from the download link below. Please note that this is naive approach and not super accurate - you have to assume that only measured object is moving and its geometry is constant. This software is designed to work like a bridge between one webcam device and several webcam software applications.
If you assume that t is a time difference between two snapshots, you can calculate the object speed as v = Δ px * s / t Multiplication gives you the number of meters per single pixel unit. Let P COG 1(x 1,y 1) be a center-of-gravity point of frame 1 and P COG 2(x 2,y 2) a center-of-gravity point of frame 2, and the distance the object moved on the image is Δ px = √(|x 2 - x 1| 2 + |y 2 - y 1| 2), which may be translated to view dimension by multiplying by scale factor s defined as s = d m/d px where d px and d m are corresponding distances from image and real view. 640 px = 2 meters), you can get the COG (center-of-gravity) point of motion detector, which may be used to calculate the distance between two consecutive frames. the naive one - assume you know the scale ratio between the image size and real view dimension (e.g. Well, there are dozens of possible solutions. I want to make a speedcam which can calculate speed of a moving object by taking subsequent snapshots, how to do it. This is most likely your Eclipse setting problem - please google for the solution or change the settings as described here. The Signal API is restricted, but it should not give you any errors.
