[0023] Please also refer to Figures 1 to 3 The non-contact facial image acquisition device provided in an embodiment of the present application will now be described. The non-contact facial image acquisition device includes a facial image acquisition device 10, which includes a light board 11, a circuit board 12, and a support column 13. The support column 13 is disposed between the light board 11 and the support column 13. The light board 11 is provided with a fill light component, a distance measuring unit 15, and a positioning hole. The circuit board 12 is provided with a main control chip (not shown), a facial image acquisition module, and a data export interface 18. The acquisition end of the facial image acquisition module is fixed in the positioning hole. The fill light component, the distance measuring unit 15, the facial image acquisition module, and the data export interface 18 are respectively connected to the main control chip.

[0024] It can be understood that, compared with the existing telescope-type iris collector, the non-contact facial acquisition instrument uses the ranging unit 15 to sense the human body and turn on the fill light component and the facial acquisition module. The fill light component fills the light on the human face and then the facial acquisition module collects the image, realizing non-contact facial acquisition and improving the acquisition range, convenience, and hygiene and safety.

[0025] The support column 13 is arranged between the lamp board 11 and the support column 13 , which, on the one hand, limits and fixes the face acquisition module, and on the other hand, forms a heat dissipation space between the lamp board 11 and the circuit board 12 to improve the heat dissipation capacity.

The heat conductive sheet 26 can enhance the heat transfer efficiency between the circuit board 12 and the rear shell 24 to increase the overall heat dissipation efficiency.

[0034] In another embodiment of this application, please refer to Figure 2 The light collection device 10 further includes a dustproof foam 27 , a light averaging plate 28 and a glass panel 29 . The dustproof foam 27 and the light averaging plate 28 are located between the light board 11 and the glass panel 29 .

[0035] It can be understood that the light-homogenizing plate 28 can make the fill light more uniform, thereby improving the effect of face and iris collection, and the dust-proof foam 27 plays a role in dust prevention and shock absorption.

[0036] In another embodiment of this application, please refer to Figure 3 The non-contact facial feature acquisition instrument further includes a tripod 30 , and the facial feature acquisition device 10 is movably disposed on the tripod 30 .
