  • Method of controlling panning and tilting of surveillance camera using edge value
    Patent number: 10878677
    Abstract: A method of controlling panning of a surveillance camera configured to perform panning over a set angle during a preset mode includes: obtaining an edge value with respect to each pixel of an object captured image of a panning-completed time, the edge value being a difference between brightness of a left adjacent pixel thereof and brightness of a right adjacent pixel thereof; obtaining an object vertical-line number among vertical pixel lines of the object captured image, the object vertical-line number being a number of a vertical pixel line in which a sum of the edge values is largest; and correcting the panning such that the object vertical-line number coincides with a reference vertical-line number corresponding to the panning over the set angle.
