Patent number: 11399141Abstract: An example holographic video recording system comprises: a first group of cameras positioned at a first position, a second group of cameras positioned at a second position, and a third group of cameras including a third infrared camera. The first group of cameras includes a first infrared camera and a first color camera; the second group of cameras includes a second infrared camera and a second color camera; and the third group of cameras includes a third infrared camera spatially positioned between the first and second infrared cameras. A depth map may be calculated using the first infrared camera and the second infrared camera in accordance with determining that an object is beyond a predefined distance from the holographic video recording system; or the first infrared camera and the third infrared camera in accordance with determining that the object is within the predefined distance from the holographic video recording system.Type: GrantFiled: October 1, 2020Date of Patent: July 26, 2022Assignee: Beijing Dajia Internet Information Technology Co., Ltd.Inventors: Ziyu Wen, Jisheng Li, Yikai Zhao, Yao Lu, Yi Xu, Zhoutian Feng, Lei Wang, Kunyao Chen, Peiyao Zhao, Xiubao Jiang
