A plurality of light sources placed at one end of a surface imaging system may generate and direct light rays to be incident onto a surface to be detected at high incident angles that are greater than or equal to a predetermined angle threshold, the predetermined angle threshold may be set to ensure that images of the surface to be detected that have at least a predetermined degree of contrast are to be obtained. An image sensor that is placed at another end of the surface imaging system may collect light rays reflected from the surface to be detected to form a first image of the surface to be detected.
