Fringe projection system

A fringe projection system for three-dimensionally capturing a surface of a measurement object, comprising a projector for projecting a fringe pattern onto the measurement object and a digital camera for capturing the fringe pattern wherein the projector comprises a binary amplitude mask having a transparent region and an opaque region, the amplitude mask has first stripe regions extending in the first direction, and wherein the ratio of opaque regions and transparent regions varies depending on the position in the second direction. In this case, first stripe regions are provided that each form a transition region between continuous opaque or transparent stripes extending in a first direction and alternate with these stripes in a second direction. 本发明披露了一种用于三维捕获测量物体的表面的条纹投影系统，包括用于将条纹图案投射到测量物体上的投影仪和用于捕获条纹图案的数码相机，其中，投影仪包括具有透明区域和不透明区域的二元振幅掩模，其中，振幅掩模具有在第一方向上延伸的第一条纹区域，并且其中，不透明区域和透明区域的比例取决于在第二方向上的位置而变化。在这种情况下，设置了第一条纹区域各自形成在第一方向上延伸的连续的不透明条纹或透明条纹之间的过渡区域，并在第二方向上与这些条纹交替。
