摘要

Provided are an apparatus and a method for executing a person detection process from an image. A divisional small region setting window is set and an image in the window is determined to be a person based on the number of moving body pixels of each divisional small region, and a first person candidate point is set in the window when the image is determined to be a person. A person determination process is executed based on an image feature quantity in a person determination detection frame, and a second person candidate point is set in the person determination detection frame when it is determined to be a person. A distribution state in a moving body detection frame of the person determination detection frame is analyzed, and an image in the person determination detection frame is determined to be a person based on an analysis result.

說明書

(b) a person determination process of determining whether or not the detected moving body is a person or a non-human object (for example, a car or the like).

Specific process examples thereof will be described later.

A flowchart illustrated in FIG. 3 is a flowchart for describing an example of a processing sequence of a process executed by the image processing system illustrated in FIG. 1.

Processes of respective steps will be described.

(Step S11)

First, each of the cameras 10-1 to 10-n connected to the network 40 captures an image and executes the analysis process on the captured image.

As described above, for example, the following image analysis process is executed:

(a) a moving body detection process of determining whether or not a moving body is included in a captured image; and

(b) a person determination process of determining whether or not the detected moving body is a person or a non-human object (for example, a car or the like).

(Step S12)

Further, the cameras 10-1 to 10-n transmit the camera-captured image and the metadata including the analysis result based on the captured image to the server 20 via the network 40.

(Step S13)

The server 20 stores the image data and the metadata associated with the image received from the cameras 10-1 to 10-n in a storage unit in the server 20.

(Step S14)
