A moving body tracking system includes: a selecting unit () that select a target camera from a plurality of cameras disposed in a monitored area; a moving body detecting device () that extracts features of a moving body detected in an image captured by the target camera; a comparing unit () that compares the extracted features with the features of a tracking target moving body, to identify the tracking target moving body; a tracking managing unit () that tracks the movement of the tracking target moving body in the monitored area based on the position of the target camera and the time at which the image including the moving body was captured; and an elevator information acquiring unit () that acquires elevator operation information indicating an operation status of an elevator from an elevator system. When the tracked moving object boards an elevator, a selecting unit () refers to the elevator operation information to specify a target floor that is a floor on which the tracking target moving body is likely to unboard the elevator and selects at least one camera disposed on the target floor out of the plurality of cameras as the target camera.

A utilizing device includes a utilizing-side inference unit that uses a utilizing-side inference network to perform inference from target data, and a utilizing-side transmitting unit that transmits the target data to a learning device when the degree of certainty of the inference result inferred by the utilizing-side inference network is lower than a predetermined criterion. The learning device includes a learning-side inference unit that uses a learning network functioning as a teacher model of a utilizing-side inference network to perform inference from the received target data to generate learning data, a learning unit that generates updated weighting coefficient information indicating weighting coefficients updated by relearning the learning-side inference network which has the same network structure as the utilizing-side inference network by using the learning data, and a learning-side transmitting unit that transmits the updated weighting coefficient information to the utilizing device to update the utilizing-side inference network.

In a state in which an optical axis of a camera is normal to a surface, a relative angle of a projector with respect to the camera is set such that a marker is formed at the intersection of the optical axis of the camera with the surface. In a state in which the relative angle is unchanged and an installation angle of the camera is changed, the marker formed on the surface is shot by means of the camera, and, based on a distance between the marker and the intersection in the image obtained by the shooting, the installation angle of the camera is calculated. Furthermore, an error of the calculated installation angle with respect to a target value is calculated and displayed. Calculation or adjustment of the installation angle can be made even if the surface on which the marker is formed is relatively narrow.

In a case where a first access request from a playback controller () is a request for requesting reading or writing in a local storage area (), a data access controller () causes a virtual-package-data file system processor () to perform reading or writing of virtual package data in the local storage area () with priority over the reading or writing of application data in an application data area () by a file system processor ().

Playback device, control method, and program

An information processing device including a reader unit connected through a connection switch to a first control section and a second control section. The first control section is connected to the connection switch by a first bus supporting a first specification. The second control section is connected to a conversion unit by a second bus supporting a second specification. The conversion unit is connected to the connection switch by a third bus supporting the first specification. When the connection switch connects the reader unit to the first control section, the second control section halts communication with the conversion unit, thereby avoiding unnecessary use of processing resources.
