Area adjustment methods and apparatuses, cameras and storage media

Abstract

The present disclosure relates to an area adjustment method and apparatus, a camera and a storage medium. The method includes: in response to detecting that a camera rotates, obtaining a rotation angle variation of the camera; according to the rotation angle variation, obtaining a transformation relationship between a world coordinate system and a pixel coordinate system corresponding to the camera; according to world coordinate data of a preset area and the transformation relationship, determining pixel coordinate data of the preset area in a current image; where the preset area indicates an area preset in a preview image before the camera rotates. In the embodiment, the preset area in the preview image does not change along with the rotation of the camera. Thus, no false identifications and false alarms will be generated during a process of identifying an object in the preset area subsequently, helping improve the identification efficiency and the use experiences.
