Human face feature point auxiliary labeling method

The invention belongs to the technical field of video monitoring, and particularly relates to a human face feature point auxiliary labeling method, which comprises the following steps of: splitting human face feature points into main feature points and secondary feature points, pre-labeling the main feature points, performing auxiliary labeling on the secondary feature points, and manually judgingwhether the positions of the feature points need to be adjusted or not; wherein in the human face image, the main feature points are composed of points which are relatively fixed in position and canrepresent key information of the face; determining the secondary feature points by two adjacent main feature points and face edge information, wherein the positions of the secondary feature points canbe flexibly changed according to requirements. A main feature point pre-marking method and a secondary feature point auxiliary marking method are fully utilized to improve the marking efficiency; theapplicability of the labeling system is enhanced in a mode of combining the main feature points with different secondary feature point labeling schemes; labeling deviation caused by subjective factors is reduced through equidistant distribution constraints of the sub-feature points.
