A structured-light pattern for a structured-light system includes a base light pattern having 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. Each sub-pattern is different from each other sub-pattern. Each sub-pattern includes n dots in a sub-row and n dots in a sub-column in which n is an integer. Each dot is substantially a same size. 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. The dots that are aligned in a sub-column are offset in the second direction from the dots of the base light pattern that are aligned in an adjacent sub-column. In one embodiment, a size of each sub-pattern in the second direction is larger than a size of each sub-pattern in the first direction by a stretching factor.
