| 摘 要： | 多年来,实现木材自动检测是国内外科学工作者努力想解决的难题之一,其中有"南林－1型"原木直径光电测量仪、瑞典的"雷玛"型、美国的"大气科学"型等,其原理大致采用激光扫描、平面镜反射、抛物镜聚焦、光电管接收的方获得一系列脉冲信号(史伯章等,1979).

| Abstract: | An instrument for auto measuring the width and length of wood board which based on the one-dimensional linear array CCD(charge coupled device)sensor and computer technique is introduced.In this instrument,double-channel linear array CCD device and electro optical system are used to measure wood board width,the measuring precision is 1 mm.The methods of light-blocked photo-electro door and computer time counting are used to measure the wood board length.The relative measuring error of length is below 1%.System liability is guaranteed with the industry pc,OEM card and anti-interference technology.User interface based on C language are used in the program to modify parameters and improve precision.The measuring result can be sent to database and output with bar code.Changing system software properly,it is compatible for non-contact measurement of industrial products boundary dimension. |
