在这项工作中，我们提出了一个框架，多摄像机，多投影仪的目标采集的基础上结构光。这种方法允许在不移动对象或采集设置的情况下重建对象，避免了独立测量的任何配准。为了克服单个投影仪的分辨率限制，我们引入了一种新的超分辨率方案。通过利用高动态范围成像，我们能够处理甚至复杂的对象，表现出很强的镜面反射。我们表明，结合迭代光束法平差，这些改进提高了所获得的点云的精度。
In this work, we present a framework for multi-camera, multi-projector object acquisition based on structured light. This approach allows the reconstruction of an object without moving either the object or the acquisition setup, avoiding any registration of independent measurements. To overcome the resolution limitations of the individual projectors, we introduce a novel super-resolution scheme. By exploiting high dynamic range imaging, we are able to handle even complicated objects, exhibiting strong specularities. We show that, combined with an iterated bundle adjustment, these improvements increase the accuracy of the obtained point cloud.
