Coded light pattern with Hermitian symmetry

摘要

The method includes identifying one or more codewords of a bit string that does not satisfy at least one codeword constraint. The method also includes removing one or more codewords from the bitstream to produce a punctured bitstream. The method further includes determining whether the punctured bit string is symmetric. The method includes generating a Hermitian symmetric codebook primitive based at least in part on the punctured bit sequence in response to determining that the punctured bit string is symmetric, wherein the Hermitian symmetric codebook primitive Can be used to form a diffractive optical element (DOE) of a structured light depth sensing system.
