Embodiment Construction

[0048] A vibration elimination method for virtual manipulator interaction, such as figure 1 As shown, at least the following steps are included:

[0049] Step 1: Initialize system parameters and equipment, and then choose whether to perform mapping parameter correction, if not, go to step 2; if yes, go to step 9;

[0050]Step 2: Obtain the 3D coordinates of the 7 joints of the human body through the 3D sensor. The 3D coordinates of the 7 joints include the left shoulder joint coordinates, the right shoulder joint coordinates, the shoulder central joint coordinates, the hip central joint coordinates, the right elbow joint coordinates, Right wrist joint coordinates and right hand joint coordinates, and also obtain the tracking status of these 7 joints;

[0051] There are three types of joint tracking state values: 0, 1, and 2, corresponding to the three situations of "tracking", "inference" and "untracking".

[0052] Step 3: Determine the user coordinate system, use the 3D coo...

Abstract

The present invention relates to a shake elimination method for virtual robot arm interaction, wherein noise reduction is performed on data used for interaction by using a Kalman filter and a time-spatial constraint condition so as to reduce or eliminate a shake phenomenon in the interaction. Furthermore, an interaction system for verification is proposed, wherein skeleton information of a user is extracted by a 3D sensor, a plurality of joint angles of a right hand and a right arm are further calculated, the obtained joint angle data is processed by using the shake elimination method, then the joint angle data is transformed into interaction data by using a novel mapping method, and the interaction data is transmitted to a virtual robot arm to update a state so as to implement the purpose of the interaction.

Description

technical field [0001] The invention belongs to the field of human-computer interaction, in particular to a shake elimination method for virtual manipulator interaction. technical background [0002] Kinect is a new 3D sensor device launched by Microsoft in 2010, which has introduced functions such as real-time motion capture, image recognition, microphone input, voice recognition, and community interaction. Through image recognition, human bodies and actions can be identified. Using Microsoft's SDK development tools, human skeleton data can be obtained, and many researchers are working on using skeleton data to conduct human-computer interaction research based on Kinect. [0003] For the bone joint data provided by Kinect, the Microsoft SDK development tool itself provides a smoothing function for processing, but this smoothing is still a primary non-specific processing method, which has little effect on many specific noises in the interaction process. For the jitter prob...
