Abstract
A surveillance camera and a control method for the surveillance camera are disclosed. The present disclosure makes it possible to determine whether at least one of a bounding box for a head region of an objected detected from a side view image and a bounding box for an entire body region thereof intersects a preset counting line, thereby counting people passing through the counting line. In the present disclosure, one or more of a surveillance camera, an autonomous vehicle, a user terminal, and a server may be linked to an artificial intelligence module, a robot, an augmented reality (AR) device, a virtual reality (VT) device, and a 5G service.
Claims18
A surveillance camera comprising:
- an image sensor;
- a processor configured to detect a head region and an entire body region;
- the processor configured to determine a first bounding box corresponding to the head region and a second bounding box corresponding to the entire body region, respectively, of a person detected from an image obtained by the image sensor;
- the processor configured to perform counting as at least one of the first bounding box and the second bounding box intersects at least one preset counting line,
- wherein, as the first bounding box and the second bounding box originate from the same object, the processor controls the counting to be performed based on only either the first bounding box or the second bounding box.
A surveillance camera comprising:
- an image sensor;
- and
- a processor configured to perform counting as at least one of a first bounding box and a second bounding box intersects at least one preset counting line,
- wherein the first bounding box indicates a head region and the second bounding box indicates entire body region, respectively, of a person detected from an image obtained by the image sensor,
- wherein, as the first bounding box and the second bounding box originate from the same object, the processor controls the counting to be performed based on only either the first bounding box or the second bounding box,
- wherein, as a plurality of different objects simultaneously traverse the counting line, and no second bounding box is detected from at least one of the plurality of objects, the processor applies a virtual second bounding box and determines whether the virtual second bounding box intersects the counting line.
A control method for a surveillance camera, the control method comprising:
- detecting a person in a side view image wherein an entire body of the detected person including a face of the detected person can be recognized;
- detecting a head region and entire body region of the detected person;
- extracting a first bounding box corresponding to the head region and a second bounding box corresponding to the entire body region;
- performing counting as the second bounding box intersects a preset counting line;
- and
- performing counting as the first bounding box intersects the counting line but there is no bounding box linked to the first bounding box.
