Abstract
A method and a system for calibrating a plurality of surveillance cameras are provided. The method includes: sampling a plurality of first images in a monitoring scene of the plurality of surveillance cameras by a sampling device and sampling a second image by each of the plurality of surveillance cameras; performing a feature matching on the plurality of first images to obtain a matching result between the plurality of first images; reconstructing a three-dimensional point set of the monitoring scene according to the matching result between the plurality first of images; and calculating parameters of each of the plurality of surveillance cameras according to the three-dimensional point set and the second image sampled by each of the plurality of surveillance cameras.
