材料表面的快速自动在线检测

On-Line Fast Automatic Measurement for the Surface Shape of Substance

采用投影条纹技术和数字滤波技术，可以精确测定材料的轮廓线，材料的高度分布以及材料的表面缺陷（位置、深度和体积），用ＦＩＲ数字滤波器滤波，３８６微机处理，可以每秒９线（每线５１２个点）的速度获取材料的表面数据，从而实现材料表面的快速自动在线检测．

By using the techniques of projection fringe and digital filter, the profile, distribution of height and surface defects of substance (example: position, deepth and volume) can be measured accurately. With the FIR digital filter and 386 microcomputer, the data of the surface shape were acquired at 9 lines per second.Therefore, it can be fulfiled the on-line fast automatic measurement for the surface shape of substance.
