基于图像识别的错位图书检测技术研究

Research on detection technology based on image recognition for dislocation books in library

针对错位图书检测技术的应用,提出一种结合颜色及直线线段检测(LSD)的图书分割方法,以及基于索书标签的图书识别方法,同时设计了相关的实现算法。在LSD方法的基础上,根据在架图书的摆放信息、颜色分割后的部分图书标签、未分割图书标签的边界直线预测结果对未分割图书进行直线检测,增加了图书分割的准确率。将提出的检测方法分别与其他直线检测分割图书方法,以及图书识别方法进行对比。通过定量和定性分析,证明提出的方法确实能够得到更准确、更可行的分割和识别结果。

Aiming at the application of detection technology for the dislocation books in library, a book segmentation method combining color with straight line segmentation detection （LSD） and a book recognition method based on book-call label are pro- posed. Their relevant implementation algorithms were designed. On the basis of LSD method, the straight line detection for undi- vided books is conducted according to the location information of the books on bookshelves, part book labels after color segmen- tation, and boundary line forecast results of the undivided book label. With the method, the accuracy of book segmentation was improved. The proposed detection method is compared with other book segmentation methods with line detection and book recog- nition method respectively. The quantitative and qualitative analysis results show that the proposed method can obtain the higher accurate and more feasible segmentation and recognition results.
