The embodiment of the invention provides a fidelity image generation method and device and electronic equipment, and belongs to the technical field of data processing, and the method comprises the steps: collecting a plurality of images comprising a target object, and determining one or more continuous actions of the target object based on the plurality of images; acquiring a texture map of a specific area on the target object and a shape constraint map of a specific element from the plurality of images; based on the texture map, the shape constraint map and the two-dimensional image information of the plurality of images, constructing a reconstruction model of the target object; and generating a fidelity image matched with input information of the target object by using the reconstructionmodel, the fidelity image comprising one or more prediction actions matched with the input information. Through the processing scheme provided by the invention, the authenticity of the generated image is improved.
