PROBLEM TO BE SOLVED: To provide a working drawing creation support method which enables working drawing creation in consideration of a distance relation by a distance of a construction site. SOLUTION: Three-dimensional point group data of an object of the working drawing creation is acquired by a laser scanner, and also two dimensional color image data is obtained by photographing a digital picture of an object of working drawing creation. The three-dimensional point group data creates a triangle patch model which connects each adjoining point, The two dimensional color image data performs digital photogrammetry of a defective section of the three-dimensional point group data, and creates a digital photogrammetry model of a part concerned in three dimension. Both models are combined, a three-dimensional synthetic model for the working drawing creation object is created, and a contour line of the three-dimensional synthetic model is extracted. The contour line is made to reflect as a working drawing by carrying out digital conversion for an extracted contour line as a CAD drawing. COPYRIGHT: (C)2005,JPO&NCIPI
