Abstract: Two-dimensional color image data is generated by capturing an image of a target object. A plurality of pixels that form the color image data are classified to generate classified image data containing the plurality of pixels to which classification information is assigned. Kernels associated with the types are determined. The kernels have sizes according to the sizes of regions formed of pixels that belong to the types. First data on a three-dimensional point cloud is generated by capturing an image of the target object. The first data is projected onto a plane to generate second data on a point cloud corresponding to the point cloud indicated by the first data and identified in a two-dimensional coordinate system. A point of the point cloud contained in the second data is associated with a pixel in the classified image data to classify the point cloud contained in the first data into the types via the point cloud contained in the second data.
