Abstract: Techniques related to calibration of wide-baseline outside-in multi camera systems are discussed. Such techniques include receiving video sequences and intrinsic parameters corresponding to each of the cameras in the system, generating first extrinsic parameters for the cameras using tracked features and the intrinsic parameters and second extrinsic parameters using location parameters corresponding to motion control systems coupled to the cameras, and combining the first and second extrinsic parameters to provide real-time calibration of extrinsic parameters for the cameras.

Abstract: Apparatus and methods for extraction and calculation of multi-person performance metrics in a three-dimensional space. An example apparatus includes a detector to identify a first subject in a first image captured by a first image capture device based on a first set of two-dimensional kinematic keypoints in the first image, the two-dimensional kinematic keypoints corresponding to a joint of the first subject, the first image capture device associated with a first view of the first subject, a multi-view associator to verify the first subject using the first image and a second image captured by a second image capture device, the second image capture device associated with a second view of the first subject, the second view different than the first view, and a keypoint generator to generate three-dimensional keypoints for the first subject using the first set of two-dimensional kinematic keypoints.
