Device for acquisition of medical images of an ulcer, comprising: - a plurality of light sources arranged on the perimeter of a closed regular plane geometry in a circular crown arrangement, and adapted to illuminate an ulcer by means of respective light beams covering the surface of the ulcer in an overlapped fashion; - image acquisition means placed within said perimeter of the light sources and adapted to acquire medical images of said illuminated ulcer; wherein said light sources are white LEDs, wherein said light sources are progressively activated in sequence one after the other, synchronizing the on times with the acquisition of the images implemented by said image acquisition means in a manner such that an image can be acquired with at least a light source switched on, acquiring, at the end of said progressive sequence, one last image with all sources simultaneously switched on, and wherein the arrangement of said light sources allows to irradiate the ulcer from different angles and to generate shadows in the ulcer so as to highlight the non-uniformity of the ulcer itself, wherein said device is positionable at a predefined distance (h) from the ulcer, directing towards the latter the light sources and the image acquisition means, and wherein said device further comprises a processing unit connected to said sources and image acquisition means and adapted to control both the illumination of the ulcer and the acquisition of the images, characterized in that the processing unit is configured to: - sequentially acquiring a plurality of images, equal to the number of light sources plus one; - performing a step of combining and averaging said images, thereby obtaining an output image; - applying a "cellular automaton" algorithm to said output image, thereby obtaining the contour of the ulcer and the contours of shadow areas within the surface of the ulcer, wherein each shadow area is generated by a difference in level existing between a skin profile and an inside of the ulcer when illuminated by said respective light beams and comprises a respective portion of ulcer extending beyond the edge of the respective contour and in the direction of a light beam emitted from a respective light source taken into consideration; - calculating the depth of the ulcer on the basis of lengths of said shadow areas defined starting from said contours of the ulcer and contour of the shadow areas. - a plurality of light sources arranged on the perimeter of a closed regular plane geometry in a circular crown arrangement, and adapted to illuminate an ulcer by means of respective light beams covering the surface of the ulcer in an overlapped fashion;
