Key point detection method and device, equipment and medium

The invention provides a key point detection method and device, equipment and a medium, and the method comprises the steps: inputting a to-be-detected image into a key point prediction model, obtaining the coordinate value of a prediction frame in the to-be-detected image, determining the coordinate value of each predicted key point in a to-be-detected object according to the coordinate value of the prediction frame, and carrying out the detection of the key point according to the key point prediction model. And obtaining a prediction mask value and a prediction fine tuning value of each prediction key point, and obtaining a target coordinate value of the prediction key point according to the coordinate value, the mask value and the prediction fine tuning value of the prediction key point. According to the technical scheme, the positioning result of the key point is obtained by combining the coordinate value, the prediction mask value and the prediction fine adjustment value of the key point obtained through
