A measuring system includes a processor. The processor calculates first information. The first information indicates a position and an attitude of a camera. The camera measures depth information along with an image of a measurement target. The processor extract second shape information from first shape information based on the first information. The first shape information indicates a three-dimensional shape of the measurement target. The second shape information indicates a three-dimensional shape corresponding to an imaging range of the camera. The processor calculates second information based on a result of a comparison between the depth information and the second shape information. The second information indicates the position and the attitude of the camera with a higher precision than the first information.
