<p><P>PROBLEM TO BE SOLVED: To acquire simply and accurately reinforcement arrangement information of a deformed reinforcement. <P>SOLUTION: A digital camera capable of setting 4 million pixels or more, and obtaining an autofocus function is determined (S701, S702), and a photographing object portion including a deformed reinforcement is determined (S705). Then, markers are applied to both two ends among a plurality of deformed reinforcements which are photographing objects (S707), and photographed from a position separated by 2 meters by using the digital camera (S708). Then, image data of the photographed deformed reinforcements are transferred from the digital camera to a portable terminal, and image processing is executed by using the portable terminal (S714). In the image processing, one pixel length which is a length per pixel in the image data is specified, and the number of pixels of a diameter length of the deformed reinforcement in the image data is counted, and the number of pixels of the diameter length and the one pixel length are multiplied together, to thereby calculate the diameter length. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
