This drawing preparation system, which prepares a shape drawing from the results of a measuring unit measuring the surroundings, is provided with: a normal line recognition unit which estimates the normal line of a plane configured by shape data measured by the measurement unit; a coordinate system calculation unit which calculates a coordinate system in having a coordinate axis in direction of the aforementioned normal line; a partial shape determination unit which sets, as partial shapes, shapes surrounded by planes orthogonal to the aforementioned coordinate axis of the coordinate system; and a shape reconstruction unit which arranges a plurality of the aforementioned partial shapes such that the partial shapes encompass the points representing the shape data and such that planes of adjacent partial shapes are smoothly connected to each other. |
