Application of embedded database SQLite in smell-seeing system

A scheme that uses embedded database SQLite to manage the tested image data in smell-seeing system based on embedded Linux is presented. On one hand, SQLite provides API that is combined with the GUI development tool wxWidgets for the development of a graphic database tool to operate the database; on the other hand, SQLite provides API to the user application program to access the database, and the system recognizes the current analyte using nearest neighbor algorithm. Simulation experiment results show that the system can recognize the analytes contained in the database quickly and accurately on the condition that the database of the system is miniature, which verifies that the application of SQLite in system image data management is effective and reliable.
