Document Type and Number:
Japanese Patent JP3342581
Kind Code:
PURPOSE:To provide an automatic diagnosing method for coating film deterioration and its device which can conduct automatic setting of calibration and a process range in evaluation of a deterioration part of painting surface based on image information taken into a computer. CONSTITUTION:The device, in which a painting surface 2 applied to a structure such as a steel bridge is taken into an image input device 3 and a deterioration part of the painting surface 2 is diagnosed based on the image, is provided with an object structure data base 9 wherein dimensions of characteristic parts of a structure to be inspected are stored; an image processing device 4 which takes in an image from the image input device 3 and detects characteristic parts in the image; and a calculating-diagnosing device 6 into which image data of the image processing device 4 as well as data of the object structure data base 9 are inputted and which conducts calibration based on both the data, determines a process range of the painting surface 2, and diagnoses deterioration of coating film.
