According to the present disclosure, there are provided an apparatus and a method in which a three-dimensional model of a target object is created from point cloud data in which each point represents three-dimensional coordinates, the three-dimensional model is superimposed on an image in which a target object of the three-dimensional model is photographed, a point cloud data to be added to a point cloud data that constitutes the three-dimensional model is selected by comparing the three-dimensional model with the target object in the image, and the three-dimensional model of the target object is created again using the point cloud data including the point cloud to be added. ## Claims ### Claim 1 An apparatus wherein a three-dimensional model of a target object is created from point cloud data in which each point represents three-dimensional coordinates, the three-dimensional model is superimposed on an image in which a target object of the three-dimensional model is photographed, a point cloud to be added to a point cloud that constitutes the three-dimensional model is selected by comparing the target object in the image with the three-dimensional model, and the three-dimensional model of the target object is created again including the point cloud to be added. ### Claim 2 (depends on 1) The apparatus according to claim 1, wherein a point cloud within a threshold from an approximate line of the three-dimensional model is selected as the point cloud to be added. ### Claim 3 (depends on 1) The apparatus according to claim 1, wherein the target object in the image is compared with the three-dimensional model using a color of the target object in the image. ### Claim 4 (depends on 3) The apparatus according to claim 3, wherein color information of the target object in the image is assigned to each point superimposed on the target object, and the point cloud to be added is selected by comparing a range of point clouds having the same color information as the target object with the three-dimensional model. ### Claim 5 (depends on 3) The apparatus according to claim 3, wherein color information of the target object in the image is assigned to each point superimposed on the target object, and the point cloud to be added is selected by extending the three-dimensional model until a point cloud having different color information from the target object appears. ### Claim 6 (depends on 1) The apparatus according to claim 1, wherein a size of the target object in the image is acquired by referring to a database storing information on the size of a random target object, and the point cloud to be added is selected by comparing the size of the acquired target object with the three-dimensional model. ### Claim 7 A method comprising: creating a three-dimensional model of a target object from point cloud data in which each point represents three-dimensional coordinates; superimposing the three-dimensional model on an image in which a target object of the three-dimensional model is photographed; selecting a point cloud data to be added to a point cloud data that constitutes the three-dimensional model by comparing the three-dimensional model with the target object in the image; and creating the three-dimensional model of the target object again using the point cloud data including the point cloud to be added. ### Claim 8 (depends on 1) A non-transitory computer-readable medium having computer-executable instructions that, upon execution of the instructions by a processor of a computer, cause the computer to function as the apparatus according to claim 1.
