Problems solved by technology

However, most methods are implemented on the premise of a simple background or require the gesturer to wear special colored gloves, which adds certain restrictions to the human-computer interaction.
The kinect-based interactive gesture segmentation method does not have the above limitations and is relatively mature, but the kinect device is expensive and difficult to apply to ordinary users

Embodiment Construction

[0045] The present invention will be further described below in conjunction with accompanying drawing.

[0046] The present invention is based on the multi-rule interactive gesture trajectory segmentation method, which is divided into the following specific steps to complete.

[0047] 1. A video camera is used to capture a video of the user's interactive gestures holding a light pen.

[0048] The present invention uses the light pen of simple and easy design, light pen such as figure 1 Shown, promptly adds a light-emitting device on common nib head. Users have the habit of holding a pen, and when using the pen with this structure, they will also use the conventional pen holding posture for operation, and the cost is low. Before the segmentation step, the present invention involves collecting and analyzing the video of the user's interactive gestures, and the device for collecting the video may be a digital video camera PCcamera connected to a computer, or a digital camera. ...

Abstract

The invention discloses an interaction gesture motion trail partition method based on multiple rules. According to the method, the video of the interaction gestures of a user holding a light pen with the hands is shot through a camera, then the motion trail points of the gestures are extracted through a Camshift method, the motion trail points are represented in a parameterization mode, constraint conditions are set, partition rules are defined, and finally the trail points are divided into intervals meeting the rules through a greedy strategy. Different partition methods can be provided according to different kinds of interaction gesture motions, the greedy strategy is adopted, the result is made to be more accurate, and efficiency is higher.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to a multi-rule-based method for segmenting motion tracks of interactive gestures. Background technique [0002] At present, some methods for segmenting motion trajectories based on interactive gestures have been studied at home and abroad. However, most methods are implemented on the premise of a simple background or require the gesturer to wear special colored gloves, which adds certain restrictions to the human-computer interaction. The kinect-based interactive gesture segmentation method does not have the above limitations and is relatively mature, but the kinect device is expensive and difficult to apply to ordinary users. Contents of the invention [0003] The purpose of the present invention is to provide a multi-rule-based interactive gesture trajectory segmentation method to overcome the complex limitations of the prior art and reduce costs. [0004] The object of the pre...
