Abstract
An information processing apparatus includes at least one memory storing instructions, and at least one processor. The at least one processor is configured to execute the instructions to acquire image data of a predetermined space captured by a camera, generate measurement data including a person-to-person distance between persons included in the image data, set space data about a size of the space, determine whether a state of density of the persons in the space is appropriate or not, based on the measurement data and the space data, and output a determination result.
Claims12
An information processing apparatus comprising:
- at least one memory storing instructions;
- and
- at least one processor configured to execute the instructions to:
- acquire image data of a predetermined space captured by a camera at a plurality of different times;
- set space data about a size of the predetermined space;
- detect at least one person included in the image data;
- generate measurement data including at least one of a number of people included in the image data, a person-to-person distance between people included in the image data, and a moving speed of the at least one person;
- set, based on the space data, reference data including a threshold for the number of people in the predetermined space;
- determine whether a state of density of people in the predetermined space is appropriate or not, based on the measurement data and the reference data;
- and
- in a case where the state of density is determined to be not appropriate, output a determination result indicating that the state of density is not appropriate and an alert signal.
An information processing method performed by a computer, the information processing method comprising:
- acquiring image data of a predetermined space captured by a camera at a plurality of different times;
- setting space data about a size of the predetermined space;
- detecting at least one person included in the image data;
- generating measurement data including at least one of a number of people included in the image data, a person-to-person distance between people included in the image data, and a moving speed of the at least one person;
- setting, based on the space data, reference data including a threshold for the number of people in the predetermined space;
- determining whether a state of density of people in the predetermined space is appropriate or not, based on the measurement data and the reference data;
- and
- in a case where the state of density is determined to be not appropriate, outputting a determination result indicating that the state of density is not appropriate and an alert signal.
A non-transitory computer-readable medium storing a program for causing a computer to perform an information processing method including:
- acquiring image data of a predetermined space captured by a camera at a plurality of different times;
- setting space data about a size of the predetermined space;
- detecting at least one person included in the image data;
- generating measurement data including at least one of a number of people included in the image data, a person-to-person distance between people included in the image data, and a moving speed of the at least one person;
- setting, based on the space data, reference data including a threshold for the number of people in the predetermined space;
- determining whether a state of density of people in the predetermined space is appropriate or not, based on the measurement data and the reference data;
- and
- in a case where the state of density is determined to be not appropriate, outputting a determination result indicating that the state of density is not appropriate and an alert signal.
