Abstract
A people-flow-estimation device includes a person-count-estimation unit for estimating the number of people included in a partial area of an image; a crowd-direction-estimation unit for estimating the direction of a crowd in the partial area; a movement-amount-estimation unit for estimating the amount of movement in the partial area; and a generation unit for extracting a partial area where people exist from a plurality of partial areas on the basis of the number of people and generating, on the basis of the number of people, the extracted partial area, and the direction and movement amount of a crowd associated with the partial area, people's flow information relating to a people's flow representing the flow of people in the partial area.
Claims15
A people-flow estimation system comprising:
- at least one memory storing a computer program;
- and
- at least one processor configured to execute the computer program to perform:
- estimating a direction of a crowd in a partial area of an image, and calculating reliability corresponding to the estimated direction;
- estimating motion of the crowd in the partial area;
- generating people-flow information indicating flow of people in the partial area based on the direction of the crowd, the motion of the crowd, and the reliability corresponding to the direction;
- clustering partial areas, including the partial area, that are adjacent each other in the image and similar in a crowd direction and motion in the partial areas;
- calculating a crowd state for the crowd based on the people-flow information regarding the clustered partial areas;
- and
- controlling a screen to display the crowd state in a mode different for each of a plurality of crowds including the crowd.
A people-flow estimation method comprising:
- estimating a direction of a crowd in a partial area of an image, and calculating reliability corresponding to the estimated direction;
- estimating motion of the crowd in the partial area;
- and
- generating people-flow information indicating flow of people in the partial area based on the direction of the crowd, the motion of the crowd, and the reliability corresponding to the direction
- clustering partial areas, including the partial area, that are adjacent each other in the image and similar in a crowd direction and motion in the partial areas;
- calculating a crowd state for the crowd based on the people-flow information regarding the clustered partial areas;
- and
- controlling a screen to display the crowd state in a mode different for each of a plurality of crowds including the crowd.
A non-transitory recording medium storing computer program, the computer program causing a computer to perform:
- estimating a direction of a crowd in a partial area of an image, and calculating reliability corresponding to the estimated direction;
- estimating motion of the crowd in the partial area;
- generating people-flow information indicating flow of people in the partial area based on the direction of the crowd, the motion of the crowd, and the reliability corresponding to the direction;
- clustering partial areas, including the partial area, that are adjacent each other in the image and similar in a crowd direction and motion in the partial areas;
- calculating a crowd state for the crowd based on the people-flow information regarding the clustered partial areas;
- and
- controlling a screen to display the crowd state in a mode different for each of a plurality of crowds including the crowd.
