Gesture sensing method, gesture sensing device and audio/video playing system

Abstract

The invention discloses a gesture sensing method, a gesture sensing device and an audio / video playing system, and relates to the technical field of image detection and processing. The gesture sensing method comprises the following steps: S1, a current frame video image of an area to be detected is acquired by a camera and received; S2, the current frame video image is compared with a previous frame video image, a S3 is executed if pixels are different, and a S4 is executed otherwise; S3, current different pixel point coordinates are acquired and saved, and the S1 is returned to; S4, the saved different pixel point coordinates are compared to obtain gesture information; S5, audio / video playing on a display device is controlled according to the gesture information. According to the gesture sensing method, the gesture sensing device and the audio / video playing system, infrared camera shooting is used for sensing and triggering control, a user can wave hands to control operational instructions including audio playing / pause, video playing / pause, circulation, special effects and the like, therefore, operation is simple, playing is flexible, and adaptability is strong.

Description

technical field [0001] The invention relates to the technical field of image detection and processing, in particular to a gesture sensing method, a gesture sensing device and an audio and video playback system. Background technique [0002] Indoor places (such as: large shopping malls, museums, exhibition halls, etc.) usually need to set up advertising players or music players for audio and video introduction or music playback, usually in three ways: continuous playback, timing playback and human-controlled playback. [0003] The continuous playback method is generally suitable for places with relatively dense traffic. It plays continuously when the traffic is large, and turns off playback when the traffic is small to save resources. However, the traffic of people changes all the time, so this method can only be used in daily It is based on the statistics of people's traffic, such as playing during the day and not playing at night, resulting in many place restrictions for co...

Problems solved by technology

Therefore, this method can be used in a wide range of places. However, this method is the same as the continuous playback method. It also needs to set the playback frequency for each use place according to the general traffic statistics, so it is troublesome to use, and it will still cause a waste of resources.

[0005] The way of artificially controlling the playback can allow the staff to control the playback of advertisements or music according to the real-time flow of people, which can achieve accurate control. However, although resources are effectively saved and the purpose is strong, it increases human resources and limits this. place of use

[0006] Although the above three methods can meet the basic requirements of audio and video playback, they are generally controlled by touch screen on-demand, and the playback content is relatively fixed, resulting in poor flexibility and adaptability to the venue.
