Embodiment Construction

[0024] The active infrared action recognition device is composed of an infrared luminescent point and an action detection device.

[0025] figure 1 It is an infrared light-emitting point 4, which is composed of an infrared LED1, a reflector 3 and a frosted glass 2. The infrared LED1 is an infrared light source, built in the middle of the infrared light-emitting point 4 . The reflector 3 is in the shape of a semi-circular arc and placed behind the infrared LED, and its function is to improve 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 receptive area of ​​the infrared light.

[0026] like figure 2 As shown, the motion detection device includes a right imaging mechanism, a left imaging mechanism, FPGA11, DSP12 and a host computer. In the right imaging mechanism, the right o...
