[0037] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0038] like Figure 1-2 As shown, the device structure of the present invention is composed of an infrared emission unit, an image acquisition unit, and a control and processing unit. The infrared emission unit includes an infrared emission circuit 2 and an 850 nm infrared LED lamp 6 . The image acquisition unit includes a lens 3 with a filter. The control and processing unit is the visual processor 7, which adopts the video image processor DM6437. The power supply is used to provide electrical energy for each of the above-mentioned power supplies.
[0039] First, the infrared emission circuit 2 of the infrared emission unit controls the switch of the infrared LED lamp 6, and emits infrared rays with a wavelength of 850 nm near the lens 3 with the filter, and the infrared emission angle is 30°. The light passes through the protective cover 5...
