摘要
根据三角法原理,导出计算煤堆高度公式,并给出该系统的成像特性曲线,最后提出正确选取物镜焦距,及激光束与摄像机水平距离 d 的一般原则。
On the basis of optical triangulation principle,formulas for calculating height of the heap of coal are derived and imaging characteristic diagrams of the system are gaven.Finally a rule for correctly selecting focul lengthf of the objective lens and horiz- ontal distanced between the laser beam and the camera are prese- nted.
