Reconstruction method of head three-dimensional model and electronic equipment

The invention provides a reconstruction method of a three-dimensional head model and electronic equipment, which are used for improving the quality of the three-dimensional head model. Comprising the following steps: for any target object, inputting a multi-view RGBD image of the target object into a pre-trained head three-dimensional model reconstruction neural network to obtain a head three-dimensional model; wherein the training mode of the head three-dimensional model reconstruction neural network is as follows: inputting a training sample into the head three-dimensional model reconstruction neural network to obtain a predicted sdf value of each rendered image, each predicted rendered image and a head three-dimensional model, the training sample comprises each rendered image after the head three-dimensional model is rendered at different visual angles and illumination and a target sdf value of each rendered image; determining a target loss value by using a first intermediate loss value obtained based on e
