And S2, processing the user image through a processing module in the cloud server to obtain the human body three-dimensional point cloud data of the user.
According to an embodiment of the present invention, a processing module in a cloud server processes a user image to obtain three-dimensional point cloud data of a user, including: calling a human body three-dimensional data calculation frame in a cloud server, and processing a user image to obtain a target area; and processing the target area by adopting a human body stereo estimation model to obtain human body three-dimensional point cloud data of the user.
Specifically, a human body three-dimensional data calculation frame is generally deployed in a cloud server in advance, a photo uploaded to the cloud server is cut, an effective area only including a human body in a user image is cut, and then three-dimensional point cloud data of a target client is obtained through a human body three-dimensional estimation model. The method for acquiring the human body stereo estimation model comprises the following steps: the method comprises the steps of collecting front photos of a target crowd (such as Asian crowd) and a 3D printing model corresponding to the front photos, continuously training an end-to-end multi-level frame constructed based on a pixel alignment function (end-to-end refers to a terminal device and a cloud server), deploying the model to the cloud server, processing and connecting and disconnecting when the server receives a user image, and obtaining human body three-dimensional point cloud data of the user.
And S3, converting the coordinates of the human body three-dimensional point cloud data of the user to obtain a human body contour map of the user.
According to one embodiment of the invention, the method for converting the coordinates of the human body three-dimensional point cloud data of the user to obtain the human body outline of the user comprises the following steps: rotating the human body three-dimensional point cloud coordinate of the user by taking the sole surface of the user as a reference so as to enable the sole of the user to be parallel to a horizontal plane; and acquiring a human body contour map of the user according to the transformed coordinates of the human body three-dimensional point cloud data.
Specifically, after the human body three-dimensional point cloud data of the user acquired in the above embodiment is obtained, coordinate transformation is performed on the human body three-dimensional point cloud data to make the sole of the human body parallel to a horizontal plane (xy plane), for example, when a human body contour map formed by the human body three-dimensional point cloud data is tilted to the left, the coordinates of the sole surface are rotated to the right to make the vertical coordinates of the sole surface the same and keep the same on the same plane, and then the coordinates of the human body three-dimensional data of other parts are rotated according to the angle of rotation of the sole surface to align the coordinates of the human body three-dimensional point cloud data, so that the human body contour map of the user can be obtained. .
And S4, acquiring the human body three-dimensional data of the user according to the target parameters of the user and the human body contour map of the user.
According to one embodiment of the invention, acquiring the three-dimensional data of the human body of the user according to the target parameters of the user and the human body outline of the user comprises the following steps: acquiring coordinates of three-dimensional point cloud data of a target part in a human body contour map of a user; projecting the coordinates of the three-dimensional point cloud data of the target part onto a horizontal plane, and acquiring the longest distance in the horizontal plane in the transverse direction and/or the longitudinal direction as the three-dimensional data of the target part in the human body contour map; obtaining human body three-dimensional data of the target part of the user according to the proportional relation between the target parameters of the user corresponding to the target part and the three-dimensional data of the target part in the human body contour map; and acquiring the human body three-dimensional data of the user according to the proportional relation between the human body three-dimensional data of the target part and the human body contour map.
In one embodiment of the invention, the target parameters of the user include: one or more of an actual height of the user, an actual waist circumference of the user, an actual shoulder width of the user, an actual chest circumference of the user, and an actual hip circumference of the user.
Wherein, the target part of the user can comprise: one or more of the height of the user, the waist circumference of the user, the shoulder width of the user, the chest circumference of the user, and the hip circumference of the user.
Specifically, the target region in the human body contour map of the user is taken as the waist as an example. The human body contour map is three-dimensional, so that the size of the waist can be obtained by obtaining point cloud data coordinates on the cross section, all three-dimensional point cloud data on the cross section are projected onto a horizontal plane, an ellipse can be obtained, and the longest transverse distance (long axis length) in the ellipse is obtained and used as waist circumference data of the waist. And taking a target part in the human body contour of the user as a chest as an example, projecting all three-dimensional point cloud data on the cross section onto a horizontal plane to obtain the chest shape of the human body, and respectively acquiring the longest distances in the horizontal direction and the longitudinal direction as the chest circumference data of the chest. And taking the target part in the human body profile of the user as the height as an example, acquiring a longitudinal section of the height, projecting the point cloud data on the longitudinal section onto a horizontal plane to obtain the height of the human body, and acquiring the longest longitudinal distance as height data. When target parameters of a user (namely actual body parameters of the user, such as actual height, actual chest circumference, actual shoulder width, actual waist circumference, actual hip circumference and the like) are input, actual human body three-dimensional data of the user can be obtained through a proportional relation with corresponding parts in a human body contour map, and the human body three-dimensional data of the user is obtained through the mode, so that personalized customization of clothes is realized.
It should be noted that, only one actual parameter, for example, height, may be input, and the ratio coefficient may be obtained from the proportional relationship between the actual height and the height in the human body profile, and the ratio between the rest of the human body profile and the height in the human body profile and the obtained ratio coefficient may be obtained, so as to obtain the whole three-dimensional data of the human body.
The method can realize the personalized customization of not only the clothes, but also any specific part of the body, such as feet. Namely, when the human body contours of the user at different angles are obtained, the foot contours can be obtained, and the three-dimensional data of the feet can be obtained by inputting the sizes of the feet, so that the personalized customization of the footwear can be realized.
In order to save time cost and better realize personalized customization, the user can be simulated to change the clothing on the application program of the terminal equipment, so that the matching degree of the clothing and the stature of the user is improved. That is to say, the cloud server can send the human body three-dimensional data to the application program of the terminal device, and the simulation user reloading is achieved through the application program.
