Embodiment 1

[0035] figure 1 It is a flow chart showing a virtual try-on method for glasses according to Embodiment 1 of the present invention. available in as Figure 4 The shown apparatus performs the method.

[0036] refer to figure 1 , in step S110, acquire the 3D point cloud data and 2D image data of the target user's head.

[0037] Here, the point data collection of the appearance surface of the scanned object obtained by the measuring instrument is called point cloud data, and the 3D point cloud data is the point data collection of the appearance surface of the scanned object obtained by a 3D image acquisition device such as a laser radar. In this embodiment, the scanning object is a human head. The 3D point cloud data includes 3D coordinate XYZ information.

[0038] The embodiment of the present invention applies the three-dimensional point cloud technology to the field of virtual glasses try-on, and obtains the corresponding model of the user's head through the three-dimensio...

Embodiment 2

[0049] figure 2 It is a flow chart showing a virtual glasses try-on method according to Embodiment 2 of the present invention, and the embodiment can be regarded as figure 1 Another specific implementation scheme of . available in as Figure 5 The shown apparatus performs the method.

[0050] refer to figure 2 , in step S201, acquire the 3D point cloud data and 2D image data of the target user's head.

[0051] Specifically, the 3D point cloud data and 2D image data of the target user's head are acquired through an image acquisition device.

[0052] In this embodiment, the 3D point cloud data of multiple viewpoints of the target user's head is obtained by scanning, the 3D point cloud data includes data of multiple frames of the target user's head, and each frame of 3D point cloud data includes at least the data of the target user's head Point cloud data, wherein the Hough forest model detection method is used to perform three-dimensional detection on multi-frame three-di...

Embodiment 3

[0106] Based on the same technical idea, Figure 4 It is a logic block diagram showing a virtual glasses try-on device according to Embodiment 3 of the present invention. It can be used to execute the flow of the glasses virtual try-on method described in the first embodiment.

[0107] refer to Figure 4 , the glasses virtual try-on device includes a data acquisition module 410 , a model generation module 420 , a data mapping module 430 , a model matching module 440 and a push module 450 .

[0108] The data acquisition module 410 is used to acquire 3D point cloud data and 2D image data of the head of the target user.

[0109] The model generation module 420 is used to generate a 3D model of the target user's head according to the 3D point cloud data.

[0110] The data mapping module 430 is used to map the two-dimensional image data into the three-dimensional model according to the corresponding relationship between the three-dimensional point cloud data and the two-dimensio...

Abstract

The embodiment of the invention provides a glasses virtual try-on method and device. The method comprises the following steps: obtaining three-dimensional point cloud data and two-dimensional image data of the head of a target user; generating a three-dimensional model of the head of the target user on the basis of the three-dimensional point cloud data; according to a corresponding relationship between the three-dimensional point cloud data and the two-dimensional image data, mapping the two-dimensional image data to the three-dimensional model; on the basis of the mapped three-dimensional model, determining, from a glasses model database storing multiple glasses models, a glasses model that matches the target user; and pushing glasses corresponding to the determined glasses model to the target user. The head of the model of the target user and the glasses corresponding to the glasses model matching the target user are obtained, and the head of the model and the glasses are combined. Therefore, a direct and lifelike glasses try-on effect is provided to the user, and the user experience is improved.

Description

technical field [0001] The invention relates to computer vision technology, in particular to a method and device for virtual glasses try-on. Background technique [0002] With the improvement of people's material living standards, consumers pay more attention to the brand, material, style and color of eyewear products, hoping to choose the most suitable glasses for their temperament and personality from a wide range of products. Usually, users choose online shopping in order to save time and other factors. [0003] However, it is not possible to try them on when dispensing glasses online. Only through the pictures provided by the merchants, it is not possible to intuitively judge whether the glasses are suitable, whether they conform to their own image, temperament, etc. In particular, the accurate measurement of the information required for glasses (such as interpupillary distance, face length and face width, etc.) often requires users to go to physical stores to complete,...
