  • Publication number: 20160262624
    Abstract: Provided are a system and method for surface condition measurement and analysis to effectively utilize image data photographed when a surface as an object is photographed regularly and continuously. When a surface as an object is sequentially photographed as time passes and the photographed image data is sequentially stored, the sequentially stored images are compared and the presence or absence of image regions among the images that nearly coincide with each other is determined. When there are images with image regions that nearly coincide with each other, a coordinate system having one image as a reference is set, and a position of the other image in the coordinate system is determined. When an image with an undetermined position overlaps with an image with a determined position, including images photographed subsequent thereto, the position of the image is determined.
