In the completion of a big festival that involves many people, the number of participants wil be anounced.
There could be up to 5 times diferences in estimation, Therefore in this study, we designed a mathematical method
for estimating the number of people in the event more precisely through photographs. We selected the time when
people are mostly gathered. In adition, we noticed that the area in the photograph is diferent from the actual
area(festival) and the unseable areas of vanishing points can be apeared. To amend this eror, we considered
the ratio of the area in the photograph to the actual festival area. Finaly, we divided the area in the photograph
that have same actual area and organized the population of each section to estimate the number of people
statisticaly.
