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

the data processing unit finally determines that the image in the person determination detection frame is a person in a case in which the occupancy rate is equal to or greater than a threshold value.

(13)

The image processing apparatus according to any of (1) to (12), in which the data processing unit generates metadata in which object type information indicating whether or not a moving body obtained as a result of the second person detection process is a person is recorded.

(14)

The image processing apparatus according to (13), in which the image processing apparatus transmits the metadata generated by the data processing unit through a communication unit.

(15)

An image processing system, including:

a camera that captures an image; and

a server connected with the camera via a network,

in which the camera includes

a data processing unit configured to execute a person detection process from the captured image, and

the data processing unit

executes a first person detection process of setting a divisional small region setting window in a moving body detection frame surrounding a moving body region detected from the captured image, determining whether or not an image in the window is a person on the basis of the number of moving body pixels of each divisional small region, and setting a first person candidate point in the window in a case in which the image is determined to be a person,
