2016-04-05 08:59:17 -0600 | asked a question | Tracking of multiple objects in openCV using C++ Hello :) I am doing a project in openCV on estimating the speed of moving vehicle using the video captured. Here the camera is stationery. I have estimated the speed of single object using centroid and Euclidean distance. Now the problem is, I am not getting how to do the same for multiple objects. Here, I need to calculate the Euclidean distance of objects between 2 subsequent frames. I am grateful if anyone would help. Thanks in advance :) Here's the code below: (more) |
2016-03-28 09:20:00 -0600 | commented answer | Formula to calculate the speed of moving vehicle using focal length in openCV I didnt get what exactly is 'y' in the above figure. And most importantly how can we calculate the real height of the object? And what is x1 and x2 in the above figure? I lately read the basic assumption you have mentioned, but here in our project we are using a static camera to capture the video. I would be glad if you answer my above doubts. |

2016-03-24 12:10:33 -0600 | asked a question | Formula to calculate the speed of moving vehicle using focal length in openCV Hello, I am doing a project on Estimating the speed of moving vehicle from the video captured in openCV. Now I have computed the speed using – (Euclidean distance between two centroids)/ time. But I exactly want the actual speed of vehicle which’s calculated using the focal length of the camera. I want to know the formula for the same. I googled it but it’s of no use. I would be grateful for your help. Thanks in advance :) |
