| 发明名称 | 3D shape measurement using dithering | ||
| 摘要 | A method for three-dimensional (3D) shape measurement includes generating fringe patterns using a dithering technique, projecting the fringe patterns onto an object using a projector, capturing the fringe patterns distorted by surface geometry of the object using an imaging device, and performing a fringe analysis to reconstruct a 3D shape of the object using the fringe patterns and the fringe patterns distorted by the surface geometry of the object. The step of generating the fringe patterns using the dithering technique may include binarizing sinuisoidal fringe patterns with the dithering technique. The step of generating the fringe patterns using the dithering technique may include applying an optimization algorithm. | ||
