Abstract
A monitoring system includes a camera module configured to photograph a subject, a laser distance sensor configured to sense a distance to the subject, the laser distance sensor being arranged in a line with the camera module, and a processor configured to acquire a first angle and a first sensing value of the laser distance sensor in response to an event, calculate a first distance between the camera module and the subject by using the first angle and the first sensing value, calculate a second angle by using the first distance, a laser angle of view of the laser distance sensor, and a laser angle of view length of the laser distance sensor, rotate the laser distance sensor up to the second angle when a difference between the first angle and the second angle exceeds a predetermined range, and acquire a second sensing value of the laser distance sensor.
