Abstract
A control device is provided and includes: an acquisition unit that acquires the number of persons from a count unit, the count unit counting up the number of persons in an area based on a detection result of a first detection unit, the first detection unit detecting a person who goes in and out through an entrance of the area; and an operation mode control unit that controls an operation mode of a processing device according to the acquired number of persons.
Claims9
A control device comprising:
- an imaging device that takes an image of a range including an entrance of the area;
- a processor and a memory configured to implement the functions of:
- a first detection unit that detects a person who goes in and out through the entrance of the area based on the image taken by the imaging device;
- a count unit that counts up the number of persons in the area based on a detection result of the first detection unit;
- an acquisition unit that acquires the number of persons from the count unit;
- an operation mode control unit that controls an operation mode of a processing device according to the acquired number of persons;
- and
- a storage unit that stores a face image registered in advance,
- wherein the processor functioning as the first detection unit collates a face image of the person who goes in and out through the entrance with the face image stored in the storage unit, based on the image acquired from the imaging device, and determines that the person who goes in and out is an out-of-target in a case where a degree of similarity between the face images is higher than a third threshold as a result of the collation, and
- the processor functioning as the count unit counts the number of persons in the area except the number of persons who are determined as the out-of-target by the processor functioning as the first detection unit.
A control method of an operation mode of a processing device, comprising:
- taking an image of a range including an entrance of an area;
- acquiring the number of persons from a count unit, the count unit counting up the number of persons in an area using a detection result of a first detection unit, the first detection unit detecting a person who goes in and out through the entrance of the area based on the image;
- and
- controlling an operation mode of a processing device according to the acquired number of persons,
- wherein a face image of the person who goes in and out through the entrance is collated by the first detection unit with the face image stored in a storage unit, based on the image acquired from the imaging device, and the person who goes in and out is determined as an out-of-target in a case where a degree of similarity between the face images is higher than a third threshold as a result of the collation, and
- the count unit counts the number of persons in the area except the number of persons who are determined as the out-of-target by the first detection unit.
A non-transitory computer readable medium storing a program causing a computer to a process for controlling an operation mode of a processing device, the process comprising:
- taking an image of a range including an entrance of an area;
- acquiring the number of persons from a count unit, the count unit counting up the number of persons in an area using a detection result of a first detection unit, the first detection unit detecting a person who goes in and out through the entrance of the area based on the image;
- and
- controlling an operation mode of a processing device according to the acquired number of persons,
- wherein a face image of the person who goes in and out through the entrance is collated by the first detection unit with the face image stored in a storage unit, based on the image acquired from the imaging device, and the person who goes in and out is determined as an out-of-target in a case where a degree of similarity between the face images is higher than a third threshold as a result of the collation, and
- the count unit counts the number of persons in the area except the number of persons who are determined as the out-of-target by the first detection unit.
