Abstract

A door status detecting method by using at least one QR code is executed by a door status detecting device including a camera unit and a processing unit. The camera unit is utilized to monitor a door having at least one QR code. The processing unit receives at least one monitoring frame of a monitoring video from the camera unit, and the processing unit further determines whether the door status of the door is at a closed status according to a position of the at least one QR code in the at least one monitoring frame. Since the processing unit utilizes the position of the at least one QR code to determine the door status, the processing unit does not need to include an Artificial intelligence (AI) model to detect the abnormal conditions. Therefore computation loads of the process unit can be reduced.

Claims18

Dependent claims

A door status detecting method, executed by a processing unit of a door status detecting device, and comprising steps of:

receiving at least one monitoring frame of a monitoring video from a camera unit of the door status detecting device;
wherein the camera unit monitors a door having at least one QR code;
determining whether the at least one QR code is read from the at least one monitoring frame;
when the at least one QR code is read from the at least one monitoring frame, determining whether a door status of the door is at a closed status according to only a position of the at least one QR code in the at least one monitoring frame, wherein data included in the at least one QR code is not relied upon in making a door status determination;
if the at least one QR code is read from the at least one monitoring frame, determining that the door status is at the closed status;
and
if the at least one QR code is not read from the at least one monitoring frame, determining that the door status is at an opened status.

4 more elements

A door status detecting device, comprising:

a camera unit, monitoring a door having at least one QR code;
a processing unit, electrically connected to the camera unit;
wherein the processing unit receives at least one monitoring frame of a monitoring video from the camera unit, and determines whether the at least one QR code is read from the at least one monitoring frame;
wherein when the at least one QR code is read from the at least one monitoring frame, the processing unit determines whether a door status of the door is at a closed status according to only a position of the at least one QR code in the at least one monitoring frame, wherein data included in the at east one QR code is not relied upon in making a door status determination;
if the at least one QR code is read from the at least one monitoring frame, the processing unit determines that the door status is at the closed status;
if the at least one QR code is not read from the at least one monitoring frame, the processing unit determines that the door status is at an opened status.
