Abstract

The invention relates to an intelligent wireless operating system and method based on grating diffraction and gesture recognition. The system includes: a gesture extraction unit, which extracts gestures in the form of infrared diffraction signals through a grating; a gesture recognition unit, which recognizes gestures The instruction information represented by the corresponding infrared diffraction signal; the instruction unit, which wirelessly operates the external controlled system to complete the instruction through the identified instruction information. Compared with the prior art, the present invention does not need an external signal source, the system is simpler, the cost is low, the system is not affected by ambient light and background conditions, and the recognition accuracy and robustness are high.

Description

technical field [0001] The invention relates to an intelligent wireless operating system and method, in particular to an intelligent wireless operating system and method based on grating diffraction and gesture recognition.

AI Technical Summary

Problems solved by technology

[0003] Due to the complexity of gestures and the interference of environmental conditions, the traditional gesture recognition technology based on direct visual analysis has low recognition efficiency and accuracy, and is not widely practicable.

The existing wireless operation technology based on gesture recognition mainly uses the effect of different gestures on external signal sources to achieve the purpose of recognition and operation. The external signal sources in this technology mainly include millimeter waves, ultrasonic waves, near-infrared light, etc. The external signal The introduction of sources often makes the system more complicated and the cost increases

For example, Chinese patent CN208384523U discloses a wireless non-contact gesture direction detection device, including the first, second, third, and fourth infrared pair tubes, the first, second, third, and fourth voltage signal amplifiers, and the first, second, and third , 4 A / D conversion modules, main control single-chip microcomputer, Bluetooth module, peripheral equipment and operated computer, the system structure is complex and the cost is high
