gathered in crowds. Although it is known that several hundred thousand people came to the capital, there are still new versions about the number of manifestations. On Sunday, he announced that 500,000 people took part in the March on June 4. people. However, other, much lower, figures also appear in the media. The Polish Press Agency reported unofficial information that the police estimated the attendance at 100,000-150,000. people. Telewizja Polska also provided similar data, citing Onet’s information from 12. Later, the portal updated the number to 300,000. TVP Info, on the other hand, stated that “Tusk miscalculated”.
Artificial intelligence can count the crowd. With an accuracy of 98 percent.
It turns out that there is a tool that can dispel doubts. This is , which with an accuracy of up to 98 percent. is able to estimate the number of people in a given area. The editors of next.gazeta.pl sent photos from the demonstration to one of the British companies specializing in this field for analysis. The representative of this company explained to us that for an accurate count of people, advance preparation is necessary, such as the proper placement of cameras and knowing their distance from the crowd. This method is perfect for stadiums, where the measurement conditions are much better controlled than in the case of a street or an entire city.
Counting people taking part in a manifestation using AI is a great idea. However, in this particular case, it would be difficult to carry out such calculations in a short time using only the recording. This would be possible if we could use static shots from surveillance cameras (CCTV), and not recordings from dynamic shots, drones or helicopters. To perform accurate calculations, the image would also need to be relatively stable, and the people being counted should no longer be moving around
– explains the specialist.
The tool could therefore be used to count the number of people visible, for example, in a specific frame recorded by an industrial camera. There are also tools that use drones to count people. However, you would have to use them on Sunday, because the analysis is carried out on an ongoing basis.
How many people at the demonstration? Artificial intelligence will tell you in real time
Another company specializing in this type of calculation confirms that video analytics based on artificial intelligence is now quite advanced. You can divide the analyzed frames into sections and set virtual boundaries of the analysis, for example, to exclude people in the background. Counting can be done automatically, on a large scale and at high speed. Tools of this type can recognize human figures in real time, checking how many human “heads” fit in the frame and estimating the number of people in a given area.

There are many tools of this type. For example, it allows you to estimate the number of people in an area, taking into account low, medium and high crowd intensity. It is an estimation tool, but quite practical, because it takes into account the number of people that can fit in a given space. For example, this tool estimates that there may be 30,000 to 60,000 people in Plac Zamkowy and its vicinity. However, to be sure how many people actually attended the march, it would be necessary to use real-time artificial intelligence.
