Gesture position flexible identification method, system and device and medium

The invention discloses a gesture position flexible recognition method. The method comprises the following steps: S1, acquiring three-dimensional information of a hand and eyes by using a depth camera; s2, determining a sight line direction, a face orientation and a hand anchor point; wherein the hand anchor point is determined by a gesture; s3, calculating a position a which starts from the hand anchor point and intersects with the display along the sight line direction; calculating a position b which starts from the hand anchor point and intersects with the display along the face direction; s4, according to the distance between the hand and the displayer and the distance between the eye and the displayer, weight values alpha and beta are given to the position a and the position b respectively, and a weighted center point c of the position a and the position b is calculated; wherein alpha + beta = 1. The method has the advantages of being large in operable range, low in cost, easy and convenient to operate a
