The City California announced this week the installation of a bicycle counter on a nearby building the bike lane of Avenida Faria Lima. The project involves a open source software , called Cyclists counter, and a camera that transmits real-time images of a stretch and counts how many vehicles passed by during the day.
In the testing phase, the initiative is part of the São Paulo Open program, which aims to increase transparency of the municipal government. By the same token, the application used to count is available for consultation and “reuse” on Github.
The tool was all developed by the Municipality innovation laboratory, LabProdam in C ++ with the CV library and its adoption by other users is even encouraged in a statement published in the Open SP page. According to the text, “with a simple camera 20 real and some technical knowledge you can install the counter itself”
The software is powered by this camera. – In this case, which is in Faria Lima, and is accompanied by humidity and temperature sensors -. and can detect and separate the static part (the street) dynamics (cars, people and bicycles) in the captured image
It also defines the space in which identifies activity , always focusing on the defined distance from the bike path, and is able to “isolate a moving object within the stretch, and accompany him on his career within the ‘area of interest’”. You can see how it works below:
If the object has analyzed the size of a bicycle and move at a certain speed, it is recorded and the number is rising. Otherwise, it is simply “ignored.” – Or at least that is the idea of the project, which still does not do this perfectly, as the developers themselves make clear
The idea of the project leaders, which should be expanded later, is available in the medium term an online service with all the data that is captured by the camera and analyzed by the software. Thus, interested in the subject will have on hand a good bank of information for studies in the future.
