Abstract

See full text

Systems, methods, and computer readable media to resolve three dimensional spatial information of cameras used to construct 3D images. Various embodiments perform communication synchronization between a first image capture system and one or more other image capture systems and generate a first flash pulse that projects a light pattern into an environment. An image is captured that includes the light pattern and a modulated optical signal encoded with an identifier of one of the first image capture system and related-camera information. A second flash from another image capture systems may flash at a second time based on the communication synchronization. During the second flash, the first image capture system captures a second image of the environment. Based on the first and second images, the first image capture system determines the orientation of the second image capture system relative to the first image capture system.
