在本文中，我们展示了如何结构光，测距系统的成本可以大大降低视觉跟踪的结构光源。为了能够使用结构化光测距仪恢复距离测量，必须知道结构化光源和光传感器的相对位置。这通常通过使用昂贵的机械致动器仔细控制这些部件中的至少一个的位置来实现。相反，我们建议很少或没有控制放置在这些组件的定位和结构光源的位置是使用视觉反馈来确定。一个低成本的原型系统采用这种原则。
In this paper we show how the cost of a structured light, range finding system can be substantially reduced by visually tracking the structured light source. To be able to recover range measurements using a structured light range finder the relative positions of the structured light source and light sensor must be known. This is typically achieved by carefully controlling the position of at least one of these components using expensive mechanical actuators. Instead, we propose that little or no control is placed on the positioning of these components and that the position of the structured light source is determined using visual feedback. A low-cost prototype system employing this principle is presented.
