Abstract

The embodiment of the invention provides a three-dimensional human body modeling method and device, electronic equipment and a storage medium. The method comprises the steps: determining a point clouddata frame sequence to be modeled; determining a point cloud data frame sequence to be modeled; determining a nearest point pair between point cloud data of each pair of adjacent frames in the pointcloud data frame sequence; taking the minimum sum of distance errors of all nearest point pairs in the point cloud data frame sequence as a target, and adjusting all the nearest point pairs to obtainregistered point cloud data; and establishing a three-dimensional human body model based on the registration point cloud data. According to the method and device, the electronic equipment and the storage medium provided by the embodiment of the invention, global registration is carried out on the point cloud data frame sequence, so that accumulated errors between the point cloud data are reduced,tight closing between the initial frame and the end frame of the point cloud data is achieved, and the modeling precision of a three-dimensional human body model is improved.

Description

technical field

[0001] The invention relates to the technical field of computer vision, in particular to a three-dimensional human body modeling method, device, electronic equipment and storage medium. Background technique

[0002] Three-dimensional human body modeling is based on computer vision and graphics methods to realize the digitization of three-dimensional information of the human body. The 3D human body model has a wide range of applications in the fields of holographic communication, film and television game production, sports analysis and guidance, anthropometry and public safety detection.

[0003] The 3D human body modeling method in the prior art, when registering the point cloud data collected by the depth camera, cannot realize the tight closure between the initial frame and the end frame of the point cloud data, so that the point cloud data obtained by registration The cumulative error of the model is large, and the accuracy of the 3D human body model is l...
