1. A scanning device for digital image scanning of a surface of an object, the scanning device comprising:
a light source;
a first image sensor, which captures a first set of images of a first region of the object, the first region being illuminated by the light source;
a second image sensor, which captures a second set of images of a second region of the object, the second region being illuminated by the light source;
a laser, which projects laser light onto the object, wherein the projected laser light has a shape of a cross on the object;
wherein the first image sensor and the second image sensor capture/cover an overlapping region on the object, the overlapping region comprising a part of the first region of the object and a part of the second region of the object;
wherein the laser light from the laser is projected onto the overlapping region;
wherein the first image sensor and the second image sensor additionally capture a third set of images and a fourth set of images, respectively, of the object including the projected laser light on the overlapping region; and
wherein the first image sensor comprises a red (R), a green (G) and a blue (B) color channel, and wherein the wavelength of the laser light is selected so that the green (G) and the blue (B) color channels, or the green (G) and the red (R) color channels, capture the third set of images of the object including the projected laser light on the overlapping region.
