CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to Taiwan Application Serial Number 108109849, filed Mar. 21, 2019, which is herein incorporated by reference in its entirety.

BACKGROUND

Technical Field

The present disclosure relates to a monitoring device and a monitoring method, and in particular to the monitoring device and the monitoring method for a depth camera.

Description of Related Art

In home security applications, the cameras are often used for environmental monitoring. However, a 2D camera cannot recognize the distance between an object and the 2D camera, and cannot judge whether the object is approaching. The image captured is affected by the shadow and the surrounding environment as well, resulting in misjudgments of recognition.

SUMMARY

An aspect of the present disclosure relates to a monitoring device. The monitoring device includes a depth camera, a memory and a processor. The depth camera is disposed in a predetermined environment and configured to capture depth image data of the predetermined environment and to generate an estimated distance of an object in the predetermined environment. The memory is configured to store a human body feature. The processor is coupled to the depth camera and the memory, and the processor is configured to perform the following operations: comparing the depth image data with the human body feature; and controlling the depth camera to perform a recording operation based on that the depth image data conforms to the human body feature and that the estimated distance is less than a first distance threshold, in order to generate video data.

An aspect of the present disclosure relates to a monitoring method, and the monitoring method includes the following operations: capturing depth image data of a predetermined environment and generating an estimated distance of an object in the predetermined environment by a depth camera; comparing the depth image data with a human body feature by a processor; and controlling the depth camera to perform a recording operation based on that the depth image data conforms to the human body feature and that the estimated distance is less than a first distance threshold by the processor, in order to generate video data.

As described above, the monitoring device and the monitoring method provided by the embodiments of the present disclosure can determine the distance between the object and the camera, and can identify whether the object is a human body. In addition, with the face recognition function, the situation of misjudgment can be reduced, and the monitoring application and home security can be improved.
