Method and device for acquiring three-dimensional reconstruction training data and electronic equipment

The embodiment of the invention provides a three-dimensional reconstruction training data acquisition method and device and electronic equipment, and the method comprises the steps: deploying a plurality of virtual cameras in a virtual three-dimensional environment, and obtaining the external parameters of each virtual camera; generating a plurality of virtual three-dimensional point coordinates in the view field range of the plurality of virtual cameras; for each virtual three-dimensional point coordinate, determining a target two-dimensional point coordinate, mapped to a two-dimensional image collected by each virtual camera, of the virtual three-dimensional point coordinate according to an external parameter and a preset internal parameter of each virtual camera, and obtaining a target two-dimensional point coordinate set corresponding to the virtual three-dimensional point coordinate; and determining each virtual three-dimensional point coordinate and the corresponding target two-dimensional point coordin
