2016-07-25 03:49:02 -0600 | commented question | assigning ID to individual blobs That is the code I followed. I am unable to find out where the blobID is created if at all. I believe below is the code in which a new Blob is created in the with the blow function he checks if the line has been crossed. I would like to have the ID of each car as it passes the line I am intrested in determining the speed of only the vehicles that have crossed the line. for that i am using a separate piece of code and would like to match a blobID to a carID |
2016-07-25 02:31:42 -0600 | asked a question | assigning ID to individual blobs Please assist. Is there any way I can assign detected blobs ids such that I can then refer to each from any where else in my code. say I want the first blob detected to have an ID = 001, second =002, ..., nth = 00n. |

2016-07-20 10:35:59 -0600 | commented answer | finding speed of vehicle in video from a mathematical point of view I understand everything you are saying I should do. I just dnt know how to code it. I got this far by following tutorials and examples. the code I have draws boxes around each car after running background subtraction. as each box is drawn a counter counts the number of boxes drawn and returns the total number of boxes hence the number of cars. am very new to opencv and learning as I go. How would I find the time and the frame at which a car is observed and leaves the scene? I understand what I need to do but have struggling with the code. |
2016-07-20 09:40:02 -0600 | commented answer | finding speed of vehicle in video May you please assist me with a code snippet. I have been able to get the frame rate total number of frames with the blow code I do not know how to get the remaining variables in order to get the speed. Thank you for the response |

2016-07-20 08:50:56 -0600 | asked a question | finding speed of vehicle in video Can you please assist me with getting the speed of vehicles in a video. I have googled a lot on this but I could not find a solution. My task was to count cars and get the speed of every car and save to a stack/array. I have been able to count the cars but I an not sure how to calculate the speed. I had imagined I would do it in this manner.
I was then hoping that speed in KM/h may be calculated as follows speed = d/[t(left)-t(enter)] I was then hoping to take each of the speeds and save then to a stack/array for further processing. I am not sure if this is the correct way of processing speed from a video. Thank you in advance. |
2016-06-10 04:46:27 -0600 | asked a question | vehicle tracking on OpenCV2.4.11 I am very new to openCV and am using 2.4.11 on visual studio 2015 I have the below code that I got off a tutorial. The code is supposed to play a video and run back ground subtraction. The code runs at times but at other times I get an
How may I solve this? In addition, I aslso get arn error at
Is there a tutorial I can read that can show me how to buils an application that can count the number of cars passing a a camera as well as get the avarage speed at which the cars are travelling. have trie to google to find tutorials but all I find are video on youtube. |
