Processing holographic videos

A depth sensing method, applicable to a holographic video recording system, comprising:

• providing the holographic video recording system comprising:
• a first group of cameras positioned at a first position, wherein the first group of cameras includes a first infrared camera and a first color camera;
• a second group of cameras positioned at a second position, wherein the second group of cameras includes a second infrared camera and a second color camera;
• and
• a third group of camera spatially positioned between the first infrared camera and the second infrared camera in a linear fashion, wherein the third group of camera includes a third infrared camera;
• wherein a first distance spaced between the first infrared camera and the second infrared camera is greater than a second distance spaced between the first infrared camera and the third infrared camera;
• calculating a first depth map using the first infrared camera and the second infrared camera spaced at the first distance;
• calculating a second depth map using the first infrared camera and the third infrared camera spaced at the second distance;
• and
• obtaining a combined depth map through fusing by using depth values from the first depth map for a first object beyond a predefined distance from the holographic video recording system, and/or using depth values from the second depth map for a second object within the predefined distance from the holographic video recording system.

A non-transitory computer readable storage medium, applicable to a holographic video recording system comprising:

• a first group of cameras positioned at a first position, wherein the first group of cameras includes a first infrared camera and a first color camera;
• a second group of cameras positioned at a second position, wherein the second group of cameras includes a second infrared camera and a second color camera;
• and
• a third group of camera spatially positioned between the first infrared camera and the second infrared camera in a linear fashion, wherein the third group of camera includes a third infrared camera;
• wherein a first distance spaced between the first infrared camera and the second infrared camera is greater than a second distance spaced between the first infrared camera and the third infrared camera;
• wherein the non-transitory computer readable storage medium comprises instructions stored therein, executable by a processor, causing the processor to:
• calculate a first depth map using the first infrared camera and the second infrared camera spaced at the first distance;
• calculate a second depth map using the first infrared camera and the third infrared camera spaced at the second distance;
• and
• obtain a combined depth map through fusing by using depth values from the first depth map for a first object beyond a predefined distance from the holographic video recording system, and/or using depth values from the second depth map for a second object within the predefined distance from the holographic video recording system.
