A device for the detection and recording of movement tracks a fingertip based on image processing by means of a lane tracking method, comprising:an image acquisition module (1), which is formed, a hand document track in an image data file to detect and to convert;an image processing module (2), which with the image acquisition module (1) is connected and is designed, skin-colored - regions in the recorded images of respective backdrops, whereby the skin color and the background colour are variable by binary coded segment, so that corresponding edges of the skin colors - regions to determine;a hand segment - evaluation module (3), which with the image processing module (2) is connected and is formed, corresponding hand - and the face segment in the digitized images to be marked and then to extract the correct hand segment;a coordinates tracking module (4), which with the hand segment - evaluation module (3) is connected, wherein the coordinates of tracking module (4) is formed, the contiguous pixels and their coordinates in the of the hand segment - evaluation module (3) to define detected hand segment, so that a rectangular outer frame of the hand segment is formed, whereupon the position of the fingertip on the basis of the individual tips points on four sides of the outer contour is selected; anda coordinates recording module (5) which, with the coordinates of tracking module (4) is connected and is formed, the finger tip in the individual images can be seen, with the coordinates of the finger tip in the individual images are recorded, and wherein the recorded coordinates can be connected to each other to form a motion tracking, so that the composite sequence from the individual coordinates for the recognition of the path of movement of the fingertip can be used.
