Embodiment Construction
[0035] see figure 1 , the system involved in the present invention is mainly composed of an image acquisition module, an image processing module, a wireless communication module and an inventory module based on the library automation system ILASIII. First, the image acquisition module collects the images of the spines of books arranged in the library through a high-resolution camera, and the captured images pass through the video decoding chip in the module to convert the analog images into digital images and input them to the TI DSP DM6446 chip of the image processing module Middle; DSP first stores the image data in DRAM, then calls the image processing program in FLASH to process the stored image data, and sends the processed image information (book title / call number) to the library through the wireless communication module Inventory processing server; the wireless communication module is based on the ZigBee protocol, which is selected for this system because of its low pow...
