FINGER POSITION DETECTION-BASED CONTROL METHOD FOR NAIL PAINTING MACHINE

WIPO Patent Application WO/2020/015489

A1

A finger position detection-based control method for a nail painting machine, the method comprising: adding a side camera (4) and a supplementary-lighting lamp (5) on the nail painting machine; and receiving a detection image (6) captured by the side camera (4) to perform a nail detection step on the basis of the detection image (6). The invention captures the detection image (6) by means of the side camera (4), and analyzes and determines, on the basis of the captured detection image (6), whether the highest point H along an outline of a finger (3) of a user is between an upper detection line (L1) and a lower detection line (L2), so as to detect whether the user finger (3) is placed at a correct position, i.e., detecting whether: the position of a nail of the user finger (3) is so high that a collision between the nail and an ink jetting component could be caused, or whether the nail of the user finger (3) is excessively low, which would result in an unclear inkjet-painted image. Therefore, by means of such detection, the invention prevents misplacement of a user finger (3) affecting nail painting.
