A wall-thickness thinning rate at a not-measured position is estimated using information having a small number of measured points. Simulation of behavior of fluid flowing inside a pipe line is performed based on wall-thickness data of pips and three-dimensional layout data of the pipe line including the pips using a computer, and simulated wall-thickness thinned data of the pipes composing the pipe line is calculated from change of the simulated behavior of fluid.

Method of offering wall-thickness thinning prediction information, and computer-readable recording medium storing wall-thickness thinning prediction program, and method of planning piping work plan

An image matching device for extracting differences between an image taken of an actual object and model data with high accuracy. The image matching device includes a model data storage unit for storing model data of a layout of component parts of a plant, an image data storage unit for storing, for example, data of images taken of the plant, a parts library containing data on parts, heat insulating material library containing information of heat insulating materials, a model correcting unit, and a matching unit. The model correcting unit produces, based on model data and parts data, synthesized image data of an image viewed from the same position and in the same direction as actual image data is obtained by taking a photo of the plant. The matching unit matches a synthesized image to a real image.
