Abstract
In recent years, it is required to acquire three-dimensional information at high speed in various fields. Previously, a structured light field (SLF) method for high-speed three dimensional measurement in 1 ms was proposed by our group. However, the SLF method has a drawback of worse depth estimation error by several tens millimeters. In this paper, a novel method to generate SLF with two projectors placed in parallel is proposed. This arrangement could produce bigger pattern change depending on the depth and made more precise estimation possible. The depth estimation experiments for precision evaluation and dynamic projection mapping experiment successfully demonstrated precise depth estimation with the error of several millimeters and high-speed estimation within 1 ms, though the measurement range was limited to approximately 100 mm.
