GESTURE RECOGNITION SYSTEM AND GESTURE RECOGNITION METHOD THEREOF

摘要

A gesture recognition system is disclosed. The gesture recognition system comprises at least one lighting module, at least one angle detecting module, an image capturing module and a gesture information control module. The lighting module is used for emitting a light. The angle detecting module receives a reflected light of the light and accordingly outputs a light sensing signal. The image capturing module is used for capturing at least one 2-D reference image for at least one hand of the user. The distance between the angle detecting module and the image capturing module is a fixed length. The gesture information control module acquires a plurality of angle data according to the light sensing signal and the 2-D reference image to calculate at least one depth data for at least one hand according to the plurality of angle data and the fixed length, so as to recognize the gestures.

1. A gesture recognition system, recognizing single-hand gestures, comprising:
a first lighting module for emitting a first light according to a first lighting control signal wherein the first light has a first light illumination range; an angle detecting module receiving a first reflection light of the first light according to an angle detecting control signal, and outputting a light sensing signal according to the first reflection light, wherein the first reflection light is generated from the reflection resulted when the first light illuminates the single hand; an image capturing module capturing at least one two-dimensional reference image of the single hand, and outputting the two-dimensional reference image, wherein the distance between the angle detecting module and the image capturing module is a fixed length; and a gesture information control module electrically connected to the first lighting module, the image capturing module and the angle detecting module, and the gesture information control module acquiring a first angle reference data and a second angle reference data respectively according to the light sensing signal and the two dimension reference image; wherein the gesture information control module calculates a depth data and a horizontal displacement data of the single hand according to the first angle reference data, the second angle reference data and the fixed length, so as to recognize gestures of the single hand; wherein the gesture information control module respectively transmits the first lighting control signal and the angle detecting control signal to the first lighting module and the angle detecting module.
