As a preferred embodiment of the present application, as shown in fig. 6 and 7, the left camera unit 41 includes a left camera 411 and a left supplementary light source 412, the left supplementary light source 412 is disposed around the periphery of the left camera 411, the right camera unit 42 includes a right camera 421 and a right supplementary light source 422, the right supplementary light source 422 is disposed around the periphery of the right camera 421, and the left supplementary light source 412 and the right supplementary light source 422 can supplement non-visible light to the left and right eyes, respectively. The left and right eye parts can be subjected to light supplement in the detection process through the arrangement of the left and right supplement light sources 422, so that the detection accuracy is improved.

The method can be realized by adopting or using the prior art for reference in places which are not described in the invention.

The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments.

The above description is only an example of the present invention, and is not intended to limit the present invention. Various modifications and alterations to this invention will become apparent to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
