基于VB的木材无损检测近红外光谱图检索系统的实现

Realization of the Retrieval System of Near-infrared Spectrogram for Wood NDT Based on VB

利用VB语言设计木材无损检测的近红外光谱图检索系统,检索关键词由"物质名"、"光谱查询"及"列表查询"组成,可分别实现已知物质名的光谱图检索、未知物质基于吸收峰位置的物质名检索及吸收峰位置相同或接近的物质名列表检索。检索界面简洁,易于操作,相对于传统的检索方法,检索的查全查准率较高。

This paper designed a near-infrared spectrogram retrieval system for nondestructive testing of wood based on VB language.The retrieval keys include substances,spectra,and lists.The system can realize the retrieval of spectrum of given material,unknown material based on absorption peak,and material list with the same or similar absorption peak.The retrieval interface is concise and easy to operate compared with the traditional method,and the system＇s recall and precision rate is high.
