1. A face image and iris image acquisition method, wherein, a face lens and an iris lens are installed on a first tripod head, a supplementary light source is installed on a second tripod head, the method comprising:
rotating the first tripod head to force the face lens and the iris lens to be in acquisition positions;
capturing a first face image and a first iris image simultaneously by the face lens and the iris lens; and
locating an iris in the first iris image, and if no iris is located, determining whether a condition for a supplementary light source rotation is satisfied, and if the condition is satisfied, rotating the second tripod head to adjust an angle or a position of the supplementary light source to enable a light spot region to avoid an iris region;
wherein, the determining whether the condition for the supplementary light source rotation is satisfied comprises:
locating the light spot region in the first iris image, and calculating an area of the light spot region;
locating facial features comprising an eye in the first face image, and locating the facial features in the first iris image;
determining whether the light spot region covers the iris region according to positions of the facial features of the same part in the first face image and in the first iris image, a position of the eye in the first face image, and a position of the light spot region in the first iris image; and
determining that the condition for the supplementary light source rotation is satisfied, if the area of the light spot region satisfies a set threshold condition and the light spot region covers the iris region.
