Abstract: A system determines relative camera locations based on one or more persons appearing in one or more acquired images. In some instances, the system receives a plurality of images from a plurality of cameras, and identifies a skeletal structure of a person in each of the plurality of images. The system then determines localization parameters for the plurality of cameras based on intrinsic physical characteristics of the plurality of cameras and the identified skeletal structure. The localization parameters may include the positional and/or orientation parameter values for one or more of the cameras. The system then triangulates positions of the identified skeletal structure represented by the plurality of pixels. The system then outputs relative location information of the plurality of cameras based on the localization parameters.
