Patent number: 10200618Abstract: The disclosure provides an approach for predicting trajectories for real-time capture of video and object tracking, while adhering to smoothness constraints so that predictions are not excessively jittery. In one embodiment, a temporally consistent search and learn (TC-SEARN) algorithm is applied to train a regressor for camera planning. A automatic broadcasting application first receives video input captured by a human-operated camera and another video input captured by a stationary camera with a wide field of view. The automatic broadcasting application extracts feature vectors and pan-tilt-zoom states from the stationary camera input and human-operated camera input, respectively. The automatic broadcasting application further applies the TC-SEARN algorithm to learn a sequential regressor for predicting camera trajectories, based on the extracted feature vectors and pan-tilt-zoom states.Type: GrantFiled: October 12, 2015Date of Patent: February 5, 2019Assignee: Disney Enterprises, Inc.Inventors: George Peter Carr, Jianhui Chen, Yisong Yue

Publication number: 20180262660Abstract: The disclosure provides an approach for mimicking human camera operation with an autonomous camera system. In one embodiment, camera planning is formulated as a supervised regression problem in which an automatic broadcasting application receives one video input captured by a human-operated camera and another video input captured by a stationary camera with a wider field of view. The automatic broadcasting application extracts feature vectors and pan-tilt-zoom states from the stationary camera and the human-operated camera, respectively, and learns a regressor which takes as input such feature vectors and outputs pan-tilt-zoom settings predictive of what the human camera operator would choose. The automatic broadcasting application may then apply the learned regressor on newly captured video to obtain planned pan-tilt-zoom settings and control an autonomous camera to achieve the planned settings to record videos which resemble the work of a human operator in similar situations.Type: ApplicationFiled: May 9, 2018Publication date: September 13, 2018Inventors: George Peter CARR, Jianhui CHEN
