Embodiment Construction

[0031] like figure 1 Shown, the present invention comprises the steps:

[0032] (1) Collect the spine image in the library, ensure that the image contains only one row of books, and try to make the spine occupy the entire image in the vertical direction, and record the image height as X M pixels, width Y M pixels; in this step, taking into account the different conditions of the external environment, by adjusting the external lighting and camera parameter settings, it is ensured that a clear spine image of the book on the shelf can be obtained.

[0033] (2) Detect the edges and straight lines in the spine image: perform edge detection on the collected spine image, and binarize the result; detect the straight lines in the binarized image through Hough transform, and obtain the inclination angle of the arrangement direction of the books, All the detected edge pixels are projected along the vertical direction of the direction to obtain the edge projection waveform.

Abstract

The invention belongs to the technical field of library management, and particularly provides an automatic book counting method based on spine image characteristics and spatial filtering. The automatic book counting method comprises the following steps: (1) collecting a spine image in a stack; (2) detecting edges and straight lines in the spine image: carrying out edge detection to the collected spine image, and carrying out binarization to a result, detecting the straight lines in a binarization image through Hough transform, obtaining an arrangement direction dip angle of books, projecting all detected edge pixels along the vertical direction of the direction, and obtaining an edge projection oscillogram; (3) carrying out low-pass filtering to the edge projection oscillogram to obtain a smoothened oscillogram; and (4) counting the books: detecting the number of wave crests in the smoothened oscillogram, wherein the number of the wave crests is the number of the books in the spine image. The method is simple in implementation, can be completely finished by a computer, and greatly lowers book counting workload and labor intensity.

Description

technical field [0001] The invention belongs to the technical field of library management, and in particular relates to an automatic book counting method based on book spine image features and spatial filtering. Background technique [0002] As a basic content in the statistical index system of higher education, book indicators are also an important part of the basic conditions for running a university. They can objectively reflect the strength and level of running a school, and play an important role in expanding the scale of running a school and striving for more funding. reference value. [0003] Book inventory is the library's self-inventory of existing properties, a true reflection of the number of books, and one of the basic data in the book statistical indicators. The purpose of book inventory is to determine the existing book property of the library, so that the property registration book is consistent with the inventory. The comprehensive inventory is a comprehensi...
