摘要
论述了在Lab VIEW提供的虚拟环境下,设计信号处理的算法对经过NI数据卡采集到的多路信号进行处理并实现实时测量任意两路信号之间的时间差的过程。然后利用测量得到的应力波在木材中传播的时间,结合应力波在木材中的传播规律,利用反细胞投影法实现二维图像的重建。
In this paper,an algorithm is used to process the data collected by NI Data Acquisition Card and achieves the measurement of time of the stress wave propagating between the two sensors in the virtual situation provided by LabView. Based on the propagation rules of stress wave in the log,the 2 D defection image of the log section can be reconstructed.
