3-D depth sensing is essential for many applications ranging from consumer electronics to robotics. Passive depth sensing techniques based on a double-helix (DH) point-spread-function (PSF) feature high depth estimation precision, minimal power consumpti
used the internal reference of a binocular camera as the reality reference to calibrate and correct the 3D information of the plant [16]. Song et al. used the ResNeXt network to realize the depth estimation of monocular images and used the estimated position depth feature as the reference to ...
Recently developed binocular or multi-ocular underwater systems can generate non-scale depth maps [12–14]. Hence, in addition to these top-down tasks, underwater vision systems possess a better ability to handle down-top tasks where we have few prior knowledge of the current underwater scenes...
The depth estimation and the mapping range of the binocular vision heavily rely on the baseline length and the calibration accuracy between the cameras [34]. On the other hand, with the advent of the RGB-D sensors which capture RGB images along with the per-pixel depth information. For ...
