There are many optical methods for extracting the geometric information of an object from an image. The structured light method based on digital fringe projection is widely employed. Sometimes the fringe patterns have some undesired invalid areas due to drastic surface profile changes of the tested object, or geometric discontinuities. In addition, a large projection angle affects the quality of the acquired data. These invalid areas may introduce difficulties for further processing. We propose to combine image fusion methods and a typical structured light system to alleviate the shadow problems created by a single projector.

条纹拼接轮廓投影仪

有许多光学方法可以从图像中提取物体的几何信息。基于数字条纹投影的结构光方法被广泛采用。有时，由于测试对象的表面轮廓急剧变化或几何形状不连续，条纹图案具有一些不希望有的无效区域。另外，较大的投影角会影响所获取数据的质量。这些无效区域可能会给进一步处理带来困难。我们建议将图像融合方法和典型的结构化照明系统结合起来，以减轻单个投影机产生的阴影问题。
