Embodiment 1

[0029] Embodiment 1: as figure 1 , figure 2 and image 3 As shown, the present embodiment is described with a sketch of an aircraft, a sketch recognition method, comprising the following steps:

[0030] S1. Get the sketch:

[0031] Specifically in this embodiment, the user draws a sketch by hand and inputs it into the system.

[0032] S2. The system performs component segmentation with semantic information on the acquired sketch:

[0033] Specifically in this embodiment, after acquiring the user’s hand-drawn sketch image, the data-driven sketch segmentation and labeling algorithm can be used to split the sketch into stroke layers, and then combine the sequence of strokes into stroke groups, including the sequence of strokes. Combine one by one; then use the existing 3D shape library, such as 3D shape galleries, Shape repository, etc., to iteratively compare the stroke group with the part diagram in the 3D shape library, and then use the label information of the 3D part to...

Abstract

The invention discloses a sketch recognition method, which comprises the following steps of S1, obtaining pictures to be processed; S2, segmenting the collected picture into parts with semantic information to obtain a part diagram of the sketch; S3, obtaining the label of the component through identifying the component diagram by using the depth learning network model; S4, associating the semanticinformation of the component with the semantic information of the object to which the component belongs; S5, outputting the label of the object to which the part belongs obtained through the semantictree. The application of the method in commodity retrieval is characterizd by comprising the following steps of 1) obtaining picture information; 2) using a retrieval system to utilize the sketch recognition method to obtain the label of the article that the user wants to find according to the picture; 3) recommending the corresponding commodity for the user according to the identified label. Themethod and the application of the invention improve the correct rate of the identification of the complete sketch, save the time for the user to select the commodity, and enhance the user experience.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a sketch recognition method integrating deep learning and semantic trees. Background technique [0002] With the popularity of the Internet, online shopping has become the preferred consumption method for people in today's society. Users only need to enter the name of the desired item on the shopping website to select the item and then place an order, which is convenient for the user and reduces the shopping cost. It is also convenient for merchants and reduces the transit cost of middlemen. However, the current way for users to purchase commodities is limited to inputting commodity names or photos of real objects, and then obtaining a recommendation list. In real life, in some cases, the user does not know the exact name of the product, nor does he have a photo of the product, and only has a rough shape in his mind. In this case, it becomes a time-consuming and difficult task t...
