Abstract
A setting assistance device includes an acquisition unit, a calculation unit and a determination unit. The acquisition unit acquires coordinates designated by a user for an image capturing a three-dimensional space. The calculation unit calculates coordinates of a position located at a predetermined distance from a position of a part of the three-dimensional space relating to the acquired coordinates. The determination unit determines a region set for the acquired coordinates based on the calculated coordinates.
Claims16
A system comprising:
- a memory storing instructions;
- and
- at least one processor configured to execute the instructions to:
- obtain a video from one or more image-capture devices;
- obtain information to set a specific region defined by one or more warning lines by manipulating a position of two or more dots on a display screen displaying the video;
- obtain a predetermined time defining a duration as staying in the specific region, based on input to the display screen;
- detect a person in the video;
- determine whether the person enters the specific region;
- provide a first report based on determination that the detected person enters the specific region;
- determine whether a length of time during which the person is detected in the specific region is greater than or equal to the predetermined time;
- provide a second report based on the determination that the length of time during which the person is detected in the specific region is greater than or equal to the predetermined time;
- and
- output an alert based on the determination that the length of time during which the person is detected in the specific region is greater than or equal to the predetermined time.
