Embodiment 1
[0047] Embodiment 1: After the gesture recognition device is powered on, multiple sensors detect the temperature for 30 minutes. After the detection is completed, calculate the average value of all the temperatures detected within the 30 minutes. If the temperature within the 30 minutes The difference between the value and the average value is less than the preset threshold, indicating that the temperature detected within the 30 minutes is relatively stable, and no user passes through the detection area of multiple sensors, and the temperature detected is the ambient temperature, then Use this average value as the current ambient temperature.

The invention provides a gesture recognition method, a gesture recognition device and a piece of equipment. The gesture recognition method comprises the steps of judging whether a current temperature value detected by each sensor of multiple sensors is in a reference environment temperature range or not; correspondingly recording time when a maximum temperature value is detected by each sensor in a first preset time period afterwards if the current temperature value detected by any one sensor of the multiple sensors is not in the reference environment temperature range; and determining a gesture action according to the time corresponding to each sensor. Through adoption of the method, the device and the equipment of the technical scheme provided by the method, the device and the equipment, the gesture action of a user is avoided from being recognized through infrared rays which are externally emitted by use of an infrared emitting tube and are harmful to body, and therefore, the security of the user is ensured when the gesture recognition is carried out.
Description
technical field [0001] The present invention relates to the technical field of equipment, in particular, to a gesture recognition method, a gesture recognition device and a device. Background technique [0002] At present, in related technologies, a low-cost gesture recognition device is constructed by two or three infrared LED lights (Light Emitting Diodes, light emitting diodes), photodiodes, and gesture sensing chips. Infrared light is then reflected back to the photodiode through obstacles (such as the user's hand), and the photodiode converts the optical signal into an electrical signal, and compares the converted electrical signal with the signal of another compensation tube before sending it to the gesture The sensor chip recognizes gestures according to the changing trend and amount of the signal. However, the above schemes all require infrared LED lamps to emit infrared rays outward, and infrared rays are harmful to the human body. [0003] Therefore, how to avoid...
