SURVEYED TWO-DIMENSIONAL FIGURE FORMING METHOD AND SYSTEM OF RUINS LEGACY OR THE LIKE

摘要

PPROBLEM TO BE SOLVED: To provide a method and a system wherein a two-dimensional figure necessary for ruins in ruin excavation investigation, instrumentation of legacy, and formation of measured figure based on it can be obtained in a short time by a precise chart, from point group data obtained by using a spot laser light scanning system three-dimensional measuring apparatus. PSOLUTION: In this method and system, three-dimensional coordinate point group data of the ruins and the legacy measured by using the three-dimensional measuring apparatus and two-dimensional figure conditions are input. The size of a two-dimensional figure is calculated from paper size to be output and resolution. Coordinates of the three-dimensional coordinate point group data are converted by the direction of visual sense, and the above date in the depth direction are converted to color density. Pixel density of the two-dimensional image is obtained by statistics processing, Density of each pixel of the two-dimensional image is newly set by using density value of peripheral pixels. An image file is out by processing like color reverse of the two-dimensional image. PCOPYRIGHT: (C)2004,JPO
