Problems solved by technology

However, different multimedia devices require specific remote control devices to operate, and not all multimedia devices can use remote control devices to remotely adjust the volume. In the PowerPoint demonstration in the classroom, the remote control device can be used to perform remote operations on the page, but the volume of the video or other multimedia can only be adjusted by the mouse
Therefore, the existing multimedia volume adjustment method has low convenience

Embodiment 1

[0059] figure 1It is a flow chart of Embodiment 1 of the multimedia volume adjustment method of the present invention. Such as figure 1 As shown, the method includes:

[0060] Step 101: Obtain a depth image of a user's gesture. The depth image includes the spatial coordinates of the hand joints in the user gesture, such as figure 2 as shown, figure 2 It is the depth image acquired in Embodiment 1 of the multimedia volume adjustment method of the present invention;

[0061] For example, a Kinect camera may be used to acquire depth images of user gestures. Kinect is a 3D somatosensory camera, which is an XBOX360 somatosensory peripheral peripheral officially announced by Microsoft at the E3 exhibition on June 2, 2009. It is a 3D somatosensory camera (developed code-named "ProjectNatal"), and it introduces functions such as real-time motion capture, image recognition, microphone input, voice recognition, and community interaction. The Kinect camera is used as the device ...

Embodiment 2

[0079] Figure 12 It is the flow chart of embodiment 2 of the multimedia volume adjustment method of the present invention; as Figure 12 as shown, Figure 12 It is a specific flow chart executed according to the multimedia volume adjustment method of the present invention. Output classification results map interest Figure 13 as shown, Figure 13 It is a classification result diagram of Embodiment 2 of the multimedia volume adjustment method of the present invention; it is shown in the figure that the classification result is the first type of gesture, and the level corresponding to adjusting the multimedia volume according to the gesture classification result is level 1, and the volume level of the first level in this embodiment The corresponding volume is 20; for example Figure 14 as shown, Figure 14 It is a schematic diagram of volume adjustment in Embodiment 2 of the multimedia volume adjustment method of the present invention.

Abstract

The invention discloses a multimedia volume adjusting method and system. The method comprises the steps of obtaining a depth image of a user posture; conducting image division of a hand target area on the depth image; obtaining a divided target area image; using a Sobel operator to conduct gesture edge profile detection according to the target area image to extract edge parameter features; using a DAG-SVMs classifier to obtain a gesture classification result according to the edge parameter features; adjusting the volume level of a multimedia according to the gesture classification result, wherein different gesture classifications correspond to different volume levels. According to the multimedia volume adjusting method and system, the control over the volume of the multimedia itself can be achieved through gesture operations simply by making multimedia equipment connected to one piece of externally-arranged depth image acquisition equipment, in the control process, a common digital gesture in life is adopted, and the external equipment is simple, high in operability and high in convenience in the whole control process.

Description

technical field [0001] The invention relates to the field of intelligent control, in particular to a multimedia volume adjustment method and system. Background technique [0002] Multimedia is a combination of various media, generally including text, sound and image and other media forms. Currently, there are two commonly used methods for controlling the volume of multimedia: one is manual adjustment through the volume button of the multimedia device; the other is remote adjustment through a remote control device. Compared with the way of manually adjusting the volume, the remote adjustment improves the convenience to a certain extent. However, different multimedia devices require specific remote control devices to operate, and not all multimedia devices can use remote control devices to remotely adjust the volume. In the PowerPoint demonstration in the classroom, the remote control device can be used to perform remote control of the page, but the volume of the video or ot...
