本文介绍了一种低成本的交互式主动单目测距仪，并说明了引入交互性的距离获取过程的效果。测距仪仅由一个摄像头和一个激光指示器组成，激光指示器上连接有三个LED。当用户沿着物体的表面沿着扫描激光器时，相机捕获点的图像（一个来自激光器，另一个来自LED），并且使用相机的观察方向和激光器的光轴进行三角测量。用户交互允许测距仪获取范围数据，其中采样率根据下伏表面结构而跨对象变化。此外，可以使用操作者对对象的了解来实现将对象与背景分离和/或在对象中找到部分的过程。
This paper describes a low-cost interactive active monocular range finder and illustrates the effect of introducing interactivity to the range acquisition process. The range finder consists of only one camera and a laser pointer to which three LEDs are attached. When a user scans the laser along surfaces of objects, the camera captures the image of spots (one from the laser and the others from LEDs), and triangulation is carried our using the camera's viewing direction and the optical axis of the laser. The user interaction allows the range finder to acquire range data in which the sampling rate varies across the object depending on the underlying surface structures. Moreover the processes of separating objects from the background and/or finding parts in the object can be achieved using the operator's knowledge of the objects.
