Provided are a method and an electronic device for generating a point cloud. The method includes obtaining, from at least one sensor of the electronic device, first sensing data corresponding to an object, obtaining a first point cloud corresponding to the object, based on the first sensing data, identifying, by using at least one artificial intelligence model, at least one outlier point indicating violation of at least one predefined rule in the first point cloud, and providing a re-photographing location guide for re-photographing the object, based on the at least one outlier point.
