Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] figure 1 An embodiment of a 3D dynamic gesture recognition method for a smart home system of the present invention is shown. A 3D dynamic gesture recognition method for a smart home system, comprising the following steps:

[0024] Step 1, the Kinect camera that is connected with computer collects depth image and RGB image;

[0025] Step 2, preprocess the depth image, remove the pure white or pure black points in the depth image, and then find the average depth of the background in the depth image;

[0026] Step 3: Perform face detection in the RGB image, use a classifier for face detectio...

Abstract

The invention relates to the technical field of computer visual sense and man-machine interaction, and particularly to a 3D dynamic gesture identification method for an intelligent home system. The method comprises the following steps: a Kinect camera connected with a computer acquiring a depth image and an RGB image; preprocessing the depth image; performing human face detection on the RGB image; extracting human face depth; separating a human body hand portion area image; searching for a palm area; and storing palm position information. The method provided by the invention can be used for controlling the intelligent home system so that conventional switch keyboard control is replaced; human hand motion is transmitted to a central system so that a human does not have to get up and go to housing products for adjustment because all that can be done by a computer and the operation method is quite easy and simple.

Description

technical field [0001] The invention relates to the technical fields of computer vision and human-computer interaction, in particular to a 3D dynamic gesture recognition method for a smart home system. Background technique [0002] There are various gesture detection methods on the Internet. For different methods, each has its advantages and disadvantages. For example, some detection methods can achieve basic accuracy, but the detection method is complicated and takes too long. It is difficult to achieve the real-time processing effect we want if it is only on a general personal computer. Secondly, gesture recognition methods are also intricate. Although some recognition methods have a low error rate, they require pre-training, and the data after training will greatly occupy the user's disk space. [0003] Kinect is the name officially released by Microsoft to the Xbox360 somatosensory peripheral peripherals, specifically a video camera, which is used as a visual sensor in...
