| Abstract: | For the purpose of overcoming the shortcomings of crowd density estimation and population statistics, this paper brings forward the crowd density monitoring technology based on Markov random field that is summarized into two steps. Further, it explains the rationality and principle of the technology in detail. In the end, it puts forward an approach by setting up a threshold to cope with the risk assessment of crowd gathering risk management in the public venues when there is a dense covering. |
