Abstract

The invention discloses a gesture recognition method and device based on multi-point TOF, and belongs to the technical field of information processing. According to the main technical scheme, the method comprises the following steps: starting an infrared time-of-flight TOF sensor; recording an entering moment when a hand to be measured enters the TOF sensor and an exiting moment when the hand to be measured exits the sensor, and calculating a signal phase calculation moment according to the entering moment and the exiting moment; and calculating a motion deviation angle of the hand to be measured relative to the central coordinate of the plane where the TOF sensing detection device is located according to the signal phase calculation moment, and determining the motion direction of the handto be measured according to the motion deviation angle and the signal phase calculation moment.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a multi-point TOF-based gesture recognition method and device. Background technique [0002] With the continuous development of social productivity and science and technology, all walks of life pay more and more attention to gesture recognition methods in human-computer intelligent interaction scenarios, such as intelligent interaction scenarios, virtual reality interaction scenarios, smart homes, etc. In the above scenarios, gesture recognition can be Bring an immersive control experience to the operator. [0003] At present, common gesture recognition is mostly implemented based on image recognition algorithms. Although this method can realize the control of gesture recognition, this method requires high processor performance, high system power consumption and high cost, and is not suitable for cost-sensitive, Application scenarios of low power consumpti...
