Problems solved by technology

However, the method based on motion history image analysis is only suitable for static backgrounds. When a person is in a complex dynamic background, it is easy to judge the motion background as the person is waving.

Abstract

The invention discloses a method and system for detecting the hand wave of a robot, and a robot. The method includes: detecting a palm at a standard position in a video stream by a cascade classifier;extracting the angular points of the palm at the standard position to obtain an angular point set; tracking and detecting each angular point in the angular point set in the video stream to obtain thecorresponding motion trajectory of each angular point; and determining whether the palm is waving according to the motion trajectory of each angular point in the angular point set. The method and system realize the hand wave detection in a complex environment, has a good anti-interference ability to dynamic background noise, and has high detection accuracy.

Description

technical field [0001] The present invention relates to the field of image recognition, in particular to a robot hand wave detection method, system and a robot. Background technique [0002] With the advancement of science and technology, artificial intelligence is becoming more and more popular, and people hope to interact with robots like real people. However, the current interaction with robots is still dominated by mouse, keyboard and touch screen, and people can no longer meet this traditional interaction method with many limitations. Therefore, we need to design some more intelligent interaction methods. Vision is an important channel for people to understand interactive information. By visually observing the body movements of the interacting objects, one can understand the interaction intention of the other party. Therefore, in order to increase the anthropomorphic features in the process of robot-human interaction, it is necessary for the robot to understand some h...
