The invention provides an object three-dimensional shape reconstruction method and device, equipment and a storage medium, and relates to artificial intelligence image processing, and the method comprises the steps: carrying out the normalization of a two-dimensional image comprising a single object, and obtaining a normalized image; inputting the normalized image into an object shape reconstruction network, obtaining corresponding feature information through a feature extractor of the object shape reconstruction network, and inputting the feature information into a generator of the object shape reconstruction network to obtain a confidence three-dimensional tensor of a predicted voxel of the object; and carrying out binarization processing on each element in the confidence coefficient three-dimensional tensor based on a preset threshold value to obtain voxels representing the three-dimensional shape of the object. According to the method, the three-dimensional structure of the object can be accurately and efficiently recovered from the two-dimensional image, the efficiency of three-dimensional shape reconstruction is improved, and manpower and material resources are saved.
