Control method and device based on gesture trajectory recognition

Abstract

A control method and device based on gesture trajectory recognition, the method comprising: acquiring user gestures collected by depth sensors; judging whether the collected user gestures match the preset control authority gestures; The first joint point data of the user's gesture matching the authority gesture; obtain the second joint point data of each user collected by each of the depth sensors; combine the first joint point data of the user's gesture with the second joint point data of each user The point data is matched and analyzed, and the second joint point data matching with the first joint point data is determined; the authority of the user identification corresponding to the second joint point data matching with the first joint point data is set as have control rights. The solution of the embodiments of the present invention can meet the requirements of multi-person control, especially the requirement of distribution of control rights during multi-person control, thereby expanding the interactive control range of gesture recognition, and is simple, real-time, and easy for engineering application.

Description

Technical field [0001] The present invention relates to the field of interactive control, in particular to a control method based on gesture track recognition and a control device based on gesture track recognition. Background technique [0002] With the development of technology, the recognition of gesture trajectories and the realization of interaction with the host based on the recognized gesture trajectories have become an important development direction of human-computer interaction. At present, there are mainly three ways of using gesture trajectory recognition to interact with the host: one is that the user wears special props, such as special gloves, to assist in identifying or improving the effect of identifying the gesture area, but this method is inconvenient to use; the second It uses an ordinary color camera to segment the captured images such as skin color, motion, texture and other information and track the human hand area to realize dynamic gesture recognition.

Problems solved by technology

[0003] However, the current human-computer interaction based on depth sensors usually realizes synchronous actions with the human body, or simple interactive control. In this interactive control, it generally involves the interactive control of a single user, which is difficult to satisfy the control of multiple people. need
