Abstract
The system and method for social distancing compliance generates an alarm when at least two people are separated by a distance that is less than a predetermined threshold value. Thermal imaging is used to detect at least two people using at least one thermal image sensor. At least one distance is calculated between the at least two people, and it is determined if the at least one distance is less than a predetermined threshold value. If the calculated at least one distance is less than the predetermined threshold value, at least one of the at least two people is alerted that a minimum safe distance is not being met.
Claims11
A method for social distancing compliance, comprising the steps of:
- detecting at least two people by thermal imaging;
- calculating distance between the at least two people, wherein the calculation includes the steps of:
- generating at least two heat maps corresponding to the at least two people, respectively;
- converting the at least two heat maps to at least two grayscale heat maps, respectively;
- converting the at least two grayscale heat maps into at least two binary images, respectively;
- detecting contours of the at least two binary images, respectively, wherein the contours correspond to contours of the at least two people, respectively;
- determining a center of each of the contours, respectively;
- and
- calculating center-to-center distance between the respective centers of the contours of the at least two people, wherein the distance between the at least two people is equal to the center-to-center distance;
- determining if the distance is less than a predetermined threshold value;
- and
- alerting at least one of the at least two people when the distance is less than the predetermined threshold value.
A system for social distancing compliance, comprising:
- at least one thermal image sensor for detecting at least two people by thermal imaging;
- a detector controller configured for calculating at least one distance between the at least two people and determining if the at least one distance is less than a predetermined threshold value, wherein the detector controller is further configured to:
- generate at least two heat maps respectively corresponding to the thermal images of the at least two people by the at least one thermal image sensor;
- convert the at least two heat maps to at least two grayscale heat maps, respectively;
- convert the at least two grayscale heat maps into at least two binary images, respectively;
- detect contours of the at least two binary images, respectively, the contours of the at least two binary images corresponding to contours of the bodies of the at least two people;
- determine a center of the contours;
- and
- calculate center-to-center distance between the centers of the contours, the distance between the at least two people being equal to the center-to-center distance between the centers of the contours;
- at least two mobile devices associated with the at least two people, respectively, each of the mobile devices including an alarm;
- and
- at least one wireless transceiver in communication with the detector controller for transmitting at least one alarm actuation signal to at least one of the mobile devices for actuating the alarm thereof when the at least one distance is less than the predetermined threshold value.
