Safety monitoring device and method

A safety monitoring method comprising:

• obtaining a password in response to a user operation on the input unit, determining that a first total number of authorized people entered area by increasing a count by one when the obtained password from the user is the same as the preset password;
• obtaining a plurality of continuous images of the area captured by each of the at least one camera at preset time intervals, each of the images comprising a distance information indicating distances between a corresponding one of the at least camera that captures the image and each object captured by the corresponding camera;
• creating a plurality of continuous 3D models of the area according to the obtained images of the area;
• determining a second total number of people entered the area according to the 3D models, wherein the second total number is determined by increasing a count by the number of people appeared in an entrance or exit of one of the 3D models which contains the highest number of people in the area;
• and
• informing each of the authorized people when the first total number is not the same as the second total number.

A storage medium storing a set of instructions, the set of instructions capable of being executed by a processor of a safety monitoring device, cause the safety monitoring device to perform a safety monitoring method, the method comprising:

• obtaining a password in response to a user operation on the input unit, determining that a first total number of authorized people entered the area by increasing a count by one when the obtained password from the user is the same as the preset password;
