Japanese Patent JP7467722

B2

To provide a system capable of efficiently managing features.SOLUTION: A captured image of a feature imaged by a camera 244 of a mobile terminal device 240 is transmitted to a server device 210 by image transmitting means 242. At this time, if the camera 244 has an imaging position addition function, an imaging position (position by absolute coordinates) is also transmitted to the server device 210. Receiving means 216 of the server device 210 receives the captured image and the imaging position. Based on the imaging position, two-dimensional projection image generating means 218 generates two-dimensional projection images for a plurality of angles when viewing surrounding three-dimensional point cloud data from the imaging position. Comparison means 220 selects a two-dimensional projection image that best matches the received captured image from among the plurality of generated two-dimensional projection images. As a result, the captured image of the feature is recorded in association with the feature of the selected two-dimensional projection image.SELECTED DRAWING: Figure 1
