中文摘要:
      文章提出了一个可用于有限空间内三维声成像的简易算法。根据回声测距原理,得到有限空间中底面上所有采样点在三维笛卡儿空间内的坐标(x,y,z),然后将其转换为计算机屏幕上的像素点的坐标(x,y),从而绘制出具有真实立体感的图像。实践证明,利用此算法可以很方便地在计算机屏幕上绘制任意旋转的三维图像。
英文摘要:
      In this paper, a simple algorithm for three-dimensional acoustic imaging in a finite space is presented. Using echo sounding, the bottom of a finite space is sampled to produce date in the three-dimensional Cartesian coordinates. These data are converted into a two-dimensional representation for display on a flat screen. The described algorithm proves very convenient in plotting 3D objects with variable viewing angles on a computer screen.
