Description

The present invention relates to an imaging device, an information processing device, a control method, and a program.

Conventionally, a surveillance camera having a PTZ mechanism registers a PTZ (pan, tilt, zoom) position as a preset according to an instruction from a user, and receives an instruction from the user to move to the PTZ preset. In this way, surveillance cameras are provided that have a function of moving to a PTZ position registered in a PTZ preset. In addition, surveillance cameras are provided with a video detection function for detecting a moving object from captured video. A user operates a user interface (UI) that includes a screen that displays images captured by a surveillance camera, and includes a detection area that defines which area in the screen is to be used for target image detection, a detection rule name, etc. Configure detection rules.

In Patent Literature 1, when a user sets a mask area for protecting privacy in imaging by a surveillance camera, the mask area specified by the screen coordinates in the image and the PTZ position at the time of imaging are sent to the surveillance camera. The surveillance camera processes the masked area as spatial coordinates based on the received masked area and PTZ position. On the other hand, when a user sets a detection rule for a video detection area, the user designates a detection area in screen coordinates and a PTZ position or a PTZ preset including the PTZ position. This enables the surveillance camera to process the detection area of the video as spatial coordinates. Also, a monitoring camera that distributes captured video to a client device has the following functions. The monitoring camera has functions including, for example, changing settings of the monitoring camera by an external device, creating, editing, and deleting PTZ presets.

Also, a group of commands for instructing creation, editing, and deletion of detection rules that specify a PTZ preset and set a detection area in spatial coordinates are implemented in the surveillance camera. As an example of a command group, a standard established by ONVIF (Open Network Video Interface Forum) is used (Non-Patent Document 1). If the PTZ preset is not specified in the ONVIF detection rule creation/edit command, the surveillance camera processes the detection area as screen coordinates. Therefore, in a surveillance camera that processes a detection area as spatial coordinates, it is necessary to associate a PTZ preset with a detection rule.

ONVIF Specification (https://www.onvif.org/specs/DocMap.html)

However, every time the user operates the PTZ, the surveillance camera creates new PTZ presets in the current PTZ and associates them with detection rules. In this case, the number of PTZ presets linked to the detection rule increases, and the PTZ presets need to be moved each time the detection area is displayed or edited, which complicates management.

An object of the present invention is to provide a technology that facilitates management of detection areas by collecting PTZ presets linked to detection areas.

In order to achieve the object of the present invention, an imaging device according to one embodiment of the present invention has the following configuration. That is, the image capturing apparatus includes an image capturing unit that captures images according to image capturing conditions, a registration unit that links and registers information indicating a detection area in an image captured according to the image capturing conditions, and the image capturing conditions, and does not include the image capturing conditions. When registration of a detection area is instructed, a judgment means for judging whether or not photographing conditions matching the photographing conditions of the photographing means at the time of the instruction are registered; Control means for performing control so that information indicating the detection area for which the registration has been instructed and the photographing conditions that match the photographing conditions are linked and registered when it is determined that the photographing conditions that match the conditions are registered. And prepare.

According to the present invention, it is possible to easily manage the detection areas by collecting PTZ presets linked to the detection areas.
