Monitoring device, method thereof

摘要

A monitoring device includes an indicating unit configured to indicate an object to be monitored; a camera to acquire time-series images; a predicting unit configured to predict the position of destination of the characteristic points belonging to a first aggregation including characteristic points having an amount of movement larger than a reference amount of movement set in advance; a detecting unit configured to detect the position of center of gravity of the changed area; a determining unit configured to determine the positions of destination as an indicating position when representative amount of movement is larger than a first threshold value and determine the position of center of gravity as the indicating position when the representative amount of movement is smaller than the first threshold value; and a control unit configured to control the indicating unit to cause the indicating unit to indicate the indicating position are provided.

主权项

1. A monitoring device comprising:
an indicator, comprising a facial feature, for indicating an object to be monitored; a motor configured to move the indicator; a camera configured to take an image of the object to be monitored and acquire time-series images; a computer processor configured to
extract a plurality of characteristic points from the time-series images, calculate amounts of movement of the respective characteristic points, predict a position of destination of the characteristic points belonging to a first aggregation including characteristic points having an amount of movement larger than a reference amount of movement set in advance, and obtain a representative amount of movement that is a representative value of amounts of movement of the respective characteristic points belonging to the first aggregation;extract a changed area on the basis of a difference between time-series images, and detect a position of a center of gravity of the changed area;determine the position of destination as an indicating position when the representative amount of movement is larger than a first threshold value and determine the position of the center of gravity as the indicating position when the representative amount of movement is smaller than the first threshold value; and a control unit configured to control the motor to cause the indicator to indicate the indicating position.
