Detailed Description
The present invention will be further described with reference to the accompanying drawings and detailed description, wherein it is to be understood that, on the premise of no conflict, the following embodiments or technical features may be arbitrarily combined to form new embodiments.
Example 1
As shown in fig. 1, the present embodiment provides a book query recommendation method based on drawing, which includes the following steps:
s1: acquiring image information input by a user; in step S1, the image information input by the user is image information drawn by the user and/or image information clicked by the user, and the image information drawn by the user is a vector draft graph. This step is mainly to obtain a basic comparison image, and there are two alternative ways, namely, a database is pre-built to store various images, wherein the images are not cover images, but are a certain image element in the cover images, and the memory of the user is not particularly accurate, so that the user can only memorize a certain part in a certain part of books; and then displayed to the user, and the corresponding image is clicked by the user. Of course, the above-mentioned method consumes much effort of the user, and can not promote the interest of the user in inquiring the borrowed books; in this embodiment, it is most preferable to provide the user with a touch screen or a drawing screen so that the user can draw on it freely, which results in higher user autonomy and better interactivity, and higher freedom of use by the user.
S2: comparing the acquired image information with the book images stored in the database to obtain a matching result; in the comparison, the similarity of the image information may be directly compared, but in addition to this, the comparison may be performed by converting the vector draft pattern into a character array to obtain the similarity, which is preferably performed in the second mode in this embodiment. The specific implementation mode is as follows:
the method is firstly aimed at constructing a database, and because book images in the database are the reference for comparison, a proper book library image storage mode needs to be selected, and the book images are mainly obtained through the following steps:
the acquisition step: collecting a cover image of a book; the cover images of all the books which can be contacted currently are required to be acquired, so that the construction of a database can be perfected, and after all the images are acquired, the books are more aimed at books of the type of painting or the type of artistic painting; other types of books with graphic covers can be provided in addition to the two types of books.
The conversion step: obtaining a vector line manuscript graph corresponding to a cover image according to the cover image of the book; this step converts the image into a vector line manuscript, so that the later comparison is more accurate, and if direct image recognition is adopted, the distinction of elements in the cover is not easy, so that the accuracy of the comparison result is also reduced.
Generating: and generating a corresponding book image according to the vector linear manuscript pattern. The generating step specifically comprises the following substeps:
automatically splitting the vector line manuscript graph to convert each curve forming the vector line manuscript graph into a path;
obtaining all combinations of each path and the paths which form the vector line manuscript graph with the rest according to an enumeration method;
each path combination is stored as a corresponding book image. Because of inaccuracy in user memory, enumeration needs to be performed as much as possible when information is stored. For example, when a book is drawn, a train, eggs, sun or a special character is present, the user only remembers the key characteristics, such as the special character and the eggs, due to the insufficiency of memory, so that when the user only draws the special character and the eggs, the probability of picking an accurate book is greatly improved. And different elements are split and combined, so that when a user draws at will, a richer book corresponding to the drawing elements of the user can be obtained.
The method aims at constructing a database, and comprises the following steps of:
mapping each path of the acquired image information and the book image in the database into a character array; the vector line manuscript graph is set, so that before comparison, all images are scaled in equal proportion and uniformly set to be the size of preset N+ N, after the equal proportion scaling, one side of the maximum size in the length or width of the image content is attached to the edge of the scaled picture cloth, and the width or length side of the relatively smaller size is scaled in a self-adaptive mode. The appropriate value of N is selected for different sizes and complexity of the graphical content. And respectively projecting the divided images in the horizontal direction and the vertical direction, counting the value of each square area in the horizontal direction and the vertical direction, and marking the distribution condition of the points in each square area by using binary codes 0 and 1. Wherein, the mark 1 represents that the region has pixel point distribution, and the mark 0 represents that the region has pixel point distribution; and then, giving a thickness value to the mapped color region, and representing the pixel point thickness of each grid region by 1/N. And counting the distribution condition and thickness value of the pixel points of each image after the square area of each image is projected in the horizontal and vertical 2 directions, and obtaining the distribution data of the pixel points of each image, wherein the distribution data is a corresponding character array.
And comparing the character array of the mapped image information with the character array corresponding to the book image, thereby obtaining a matching result. And matching the vector line manuscript graph drawn by the user with each curve of the vector graph of each book cover. And sequencing the similarity from high to low, and taking a combined draft path corresponding to the curve with the highest similarity.
S3: and displaying the matching result. The matching result is a similarity ranking result, and the similarity ranking result comprises book image similarity ranking. And according to the matching result, the hand drawing shape of the user is completed, the drawing process is displayed on a display screen, after the completion of the completion drawing of the book cover graph, the query and borrowing two-dimensional code of the book is displayed, the book information is checked and borrowed after the user scans, a recommendable button can be displayed, and the user can draw the graph again by clicking the button to obtain the query and recommendable book. The completion is mainly performed on the image drawn by the user, the matched line paths are replaced by the line manuscript drawn by the user, and the rest combination paths corresponding to the line paths are used for completing the book line manuscript, so that the hand drawing trace of the user can be reserved.
S4: and automatically completing lines of the image information input by the user according to the book image selected by the user, and displaying corresponding book position information. The method is mainly aimed at providing a plurality of books for users to select when more matching results exist, and the accuracy of the matching results can be further improved through the method. After the completion of the graphic completion drawing of the book cover according to the image selected by the user, displaying the query and borrowing two-dimensional code of the book for the user to view and borrow the book information after scanning, displaying a recommendable button, and enabling the user to draw the graphic again by clicking the button to obtain the book recommendation.
According to the invention, after the user manually draws the line manuscript image on the touch screen, the hand-drawn image of the user is matched with the book cover image, and then the corresponding matched book is recommended to the user, and the user borrows the book by browsing the book cover image and scanning the two-dimensional code, so that the process of borrowing and recommending the book is more interesting and attractive.
