An embodiment of the present invention provides a volume adjustment method and system, relates to the field of electronic technology, and is used to make up for the technical defects that the volume is low in precision and easy to be affected by the environment at present. The volume adjustment method comprises the following steps: combining images, which contain a human body and are simultaneously shot by a first camera and a second camera respectively at each moment of N shooting moments within preset time, into N three-dimensional images; extracting a human body contour in the three-dimensional image corresponding to a first image, wherein the first image is any image shot by the first camera at N shooting moments; acquiring distance information corresponding to at least one pixel point in the human body contour from the three-dimensional image corresponding to the first image; matching the distance information corresponding to at least one pixel point determined in each of the N three-dimensional images with a corresponding relationship between the volume and the distance in a standard volume adapter library within the preset time, to determine a target volume adjustment range; and executing a corresponding volume adjustment instruction according to the target volume adjustment range. The embodiment of the present invention can be used for television identification.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a volume adjustment method and system. Background technique [0002] With the development trend of intelligent terminals such as televisions, the traditional control of televisions through control devices (eg, mouse, keyboard, and remote controller, etc.) cannot meet the needs of modern users. Seriously affected the development and application of intelligent TV. In this context, the volume adjustment operation is to increase the volume adjustment function corresponding to the different distance information stored in the user's preference in the smart TV, so that the user can control the terminal equipment such as the smart TV through distance recognition. The most intuitive control method enables people to realize the flexible control of the smart TV more conveniently and improves the user experience. [0003] In the prior art, some manufacturers use infrared detection to d...
