Fully in Tensor Computation Manner: A One-Shot Dense 3D Acquisition Method using Structured Light

Fully in tensor computation manner: one‐shot dense 3D structured light and beyond

“…For the correspondence search we propose tensor‐SGM (tSGM) [8], innovated from SGM [3], which searches for the disparity map that minimises an approximated global cost between two images with known epipolar geometry (cf. Section 5.2).…”

“…A cornerstone of our proposed system is ‘tensor shift’ manoeuvre, which enables the tensorisation of SGM into tSGM [8], so that to be easily cast into parallel computing devices using tensor processing libraries (PyTorch in our work). Concrete derivation and examples are in Section 6.…”
