Method for improving the quality of a set of a three dimensional (3D) point cloud data representing a physical surface by detecting and filling null spaces (606). The method includes analyzing (206) the data to identify the presence of a plurality of level 1 fractals (401), each defined by a plurality of voxels (400) containing data points arranged in one of a plurality of three-dimensional patterns. The method also includes selectively filling (212) voxels in the 3D point cloud data with a first predetermined limited number of data points to increase a number of instances where level 2 fractals (604) can be used for representing the 3D point cloud data. Each level 2 fractal is defined as a common plurality of the level 1 fractals having a common three-dimensional pattern, where the common plurality of level 1 fractals are also arranged in accordance with the common three dimensional pattern.

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.
