Abstract:
A structured-light pattern for a structured-light system includes a base light pattern that includes a row of a plurality of sub-patterns extending in a first direction. Each sub-pattern is adjacent to at least one other sub-pattern, and each sub-pattern is different from each other sub-pattern. Each sub-pattern includes a first number of portions in a sub-row and a second number of portions in a sub-column. Each sub-row extends in the first direction and each sub-column extends in a second direction that is substantially orthogonal to the first direction. Each portion may be a first-type portion or a second-type portion. A size of a first-type portion is larger in the first direction and in the second direction than a size of a second-type portion in the first direction and in the second direction. In one embodiment, a first-type portion is a black portion and the second-type portion is a white portion.
