Embodiment Construction

[0063] A visual following method based on monocular gesture recognition proposed by the present invention will be described in detail below in conjunction with the accompanying drawings, taking a human body as an example of a tracking target.

[0064] 1) if figure 1 As shown, the robot takes the first scene picture including human gestures through the camera module, and the picture resolution is W1*H1; it is agreed that the coordinates of the first point in the upper left corner of the captured picture are (1,1), and the last The coordinates of a point are (W1, H1); gestures can be marked by the palm or fingers, or other organs.

[0065] 2) if figure 2 As shown, the robot recognizes the gestures of the human body, and through the gesture recognition software, recognizes the gestures of the human body (such as the front palm), and obtains the position and size parameters of the gesture in the picture frame:

[0066] X1: The x-axis starting point of the gesture in the first sce...

Abstract

A visual tracking method based on monocular gesture recognition, and a robot, capable of timely obtaining a precise deviation angle between a robot and a tracking target by recognizing a featured gesture, thereby implementing easy and precise tracking and more smooth tracking actions. In addition, an initial distance can be measured by a single point ranging module; a precise relative distance between a robot and a tracking target can be timely obtained, thus achieving high tracking precision. The method and the robot feature accuracy higher than that of color block tracking, greatly reduced costs compared with a 3D motion sensing solution, greatly improved tracking accuracy, smooth user interaction, and easily mastered operation points, and are easy to use.

Description

technical field [0001] The invention relates to the technical field of robot monitoring, in particular to a visual following method based on monocular gesture recognition. Background technique [0002] At present, most household service robots have a monocular camera. Most of the human body following systems based on a monocular camera use the method of color block following. When the program is started, a preview area of ​​the monocular camera is specified, and it is followed continuously during the subsequent target movement. target walking. But this method has the following defects: [0003] 1. The color block following method is used to track according to the specified initial color block. Due to the defects of the color block following method, the target is very easy to follow; [0004] 2. The operation is cumbersome, and it is difficult for users to understand the main points of operation. Contents of the invention [0005] The problem to be solved by the present ...
