EVALUATION METHOD AND EVALUATION DEVICE FOR FACIAL KEY POINT POSITIONING RESULT

摘要

Disclosed are an evaluation method and evaluation device for a facial key point positioning result, wherein the implementation of the method comprises: acquiring a facial image, and acquiring a positioning result coordinate of a key point of the facial image (101); performing normalization processing on the positioning result coordinate and an average facial model, so as to obtain a normalized facial image (102); and extracting a facial feature value of the normalized facial image, and calculating an evaluation result according to the facial feature value and a weight vector (103). After a positioning result coordinate is obtained, normalization processing is implemented by means of an average facial model, and according to a facial feature value of a normalized facial image and a weight vector, an evaluation result is then worked out. The whole evaluation process does not need manual intervention, the evaluation speed is high, and parameters used for the calculation of an evaluation result can be quantified, so the evaluation result can be quantified.
