Three-dimensional reconstruction method, device and equipment based on target identification and model matching

The invention provides a three-dimensional reconstruction method, device and equipment based on target identification and model matching, relates to the technical field of three-dimensional modeling, and is used for solving the problem of low three-dimensional reconstruction efficiency. The method comprises the following steps: determining corrected real geographic coordinates of a plurality of pixel points only according to pixel coordinates of the plurality of pixel points corresponding to each image target in an acquired image; wherein the acquired image is an image which is acquired for a target area and contains depth information, and the plurality of pixel points comprise a centroid and boundary angular points; target model samples corresponding to the image targets meeting a preset similarity condition are determined from a preset model sample library; wherein the model sample library comprises a plurality of facility model samples and sample information of the plurality of facility model samples; and
