Problems solved by technology

[0002] At present, the known household robots can only perform simple household cleaning, without the addition of multi-sensory systems such as vision and hearing, and the functions they can provide are limited, so they cannot be called intelligent robots.
In terms of monitoring, there is currently no non-invasive product that can provide the function of following monitoring; in terms of picking up objects, the current picking up robots are less accurate and flexible

Embodiment Construction

[0013] (1) Attitude acquisition and processing module

[0014] 3D stereo vision dynamic acquisition and analysis. The three-dimensional stereo vision acquisition equipment is used to realize the dynamic establishment and recognition of three-dimensional space data, especially the recognition function of the human body's movement posture. Identify the skeleton information in the 3D image and return the key joint coordinates, and then judge the target posture and motion trend through the combination of the 3D coordinates of each joint and time. The flow chart of this module is figure 2 .

[0015] (2) Communication module

[0016] The upper computer communicates with people through the Internet and cellular mobile network. The upper computer is equipped with a WIFI module and a GSM wireless module. When the elderly suffer from sudden collapse, they can send distress information to the elderly and children through the Internet or short messages in time.

Abstract

The invention discloses a home service robot based on three-dimensional vision, and particularly relates to a method for monitoring a target, and taking an article according to a command. In the method, the skeleton and the posture of the target are identified by virtue of an RGB-D sensor, and recorded in real time, an alarming action is made in case of accidental falling-down of the target, the bit number of the recorded data is far less than that of the recorded video image, and a scene in case of accidental falling-down can be restored; and a gesture indication direction of a user can also be identified by virtue of the RGB-D sensor to obtain the approximately angular coordinates of the article to be taken, and the article can be rapidly and accurately taken in combination with a voice command. A Mecanum wheel omnidirectional moving platform is used, and can realize follow-up movements with various tracks under a complex indoor environment.

Description

technical field [0001] The invention relates to a robot device for providing home service, in particular to a home robot capable of intelligently fetching objects and monitoring falls of the elderly. Background technique [0002] At present, the known household robots can only perform simple household sanitation and cleaning without the addition of multi-sensory systems such as vision and hearing, and the functions they can provide are limited, so they cannot be called intelligent robots. In terms of monitoring, there is currently no non-invasive product that can provide the function of following monitoring; in terms of picking up objects, the current picking up robots are less accurate and flexible. [0003] The emergence of RGB-D sensors has brought new development opportunities for human gesture recognition and object segmentation and positioning. In gesture recognition, it can obtain human skeleton information, including some gestures, so as to realize gesture recognitio...
