Embodiment Construction
[0030] A gesture interaction method based on joint point transformation in this embodiment includes the following steps:
[0031] 1) Place the Kinect camera on the rotating platform, and simultaneously collect the color images and depth map information of the 3D human hand under 35 viewing angles by rotating the rotating platform. The initial viewing angle is recorded as 0°, and the rotating platform records data every 10° until Rotate to a 350° viewing angle, and obtain the 3D point cloud data of the 3D human hand under 35 viewing angles from the depth map information;
[0032] 2) Use the improved ICP registration algorithm to obtain the initial 3D point cloud data of the 3D hand from 35 viewing angles;
[0033] 3) Denoising, repairing and streamlining the initial 3D point cloud data of 3D hands to obtain complete 3D point cloud data of 3D hands;
[0034] 4) According to the shape characteristics of the human hand, the complete 3D point cloud data of the 3D human hand is div...

The invention belongs to the technical field of a three-dimensional gesture interaction method, and specifically relates to a gesture interaction method based on joint point transformation. The invention mainly solves the technical problems of expensive devices used and poor authenticity of obtained human hand models in the prior three-dimensional gesture interaction method. According to the invention, three-dimensional point clouds are processed with information in colour images synchronously obtained by a Kinect camera while acquiring point cloud data, in the scheme, a base function construction method based on geodesic distance is adopted in reconstruction, and a curved surface representation function is a high-order derivable parametric form and can guarantee topological property and surface smoothness of the human hand; meanwhile, joint points can be effectively extracted by a method of inter-dimensional matching between the three-dimensional point clouds and a two-dimensional image. The method in the scheme has the characteristics of more accurate, fast extraction speed and low computation load relative to the conventional method of reconstructing the three-dimensional joint points after performing matching between the images.
Description
technical field [0001] The invention belongs to the technical field of three-dimensional gesture interaction methods, and in particular relates to a gesture interaction method based on joint point transformation. Background technique [0002] In the initial development stage of virtual reality technology, the operating tools for human-computer interaction are only some simple external devices such as keyboards, mice, and joysticks. The user uses both hands to realize the purpose of casual communication between the virtual world and the real world. With the rapid development of virtual reality technology, simple interactive tools such as mouse and keyboard and traditional interactive interface can no longer meet the requirements of advanced human-computer interaction. And born. As a means of communication second only to language, human hands play an indispensable role. In an environment where language transmission is impossible, people can express and understand each other...
