The invention discloses a threaded hole center coordinate extraction method, device and equipment, and belongs to the technical field of building machinery. The threaded hole center coordinate extraction method comprises the steps that point cloud data and image data of a to-be-detected structural component are acquired, and the to-be-detected structural component comprises at least one threaded hole; extracting spatial features of the point cloud data and texture features of the image data; fusing the spatial features and the texture features to obtain fused features; and inputting the fused features into a deep learning model, and outputting hole center coordinates of the threaded hole in the to-be-detected structural component. The point cloud data and the image data can be combined, the hole center coordinates of all the threaded holes in the structural component to be measured can be automatically measured, the limitation in the prior art is overcome, and the measurement precision and efficiency can be i
