Example Embodiment

[0027] The active infrared action recognition device is composed of an infrared light-emitting point and an action detection device.

[0028] figure 1 It is an infrared light-emitting point 4, which is composed of an infrared LED1, a reflector 3 and a ground glass 2. The infrared LED 1 is an infrared light source, and is built in the middle of the infrared light emitting point 4. The reflector 3 has a semicircular arc shape and is placed behind the infrared LED, and its function is to increase the utilization rate of the light source. The frosted glass 2 is placed in front of the infrared LED, and its function is to change the direct light emitted by the infrared LED 1 or reflected by the reflector 3 into scattered light and increase the receiving area of ​​infrared light.

[0029] Such as figure 2 As shown, the motion detection device includes a right imaging mechanism, a left imaging mechanism, FPGA 11, DSP 12 and a host computer. In the right imaging mechanism, the right filt...
