<p>PURPOSE:To detect to find out appropriately and to make proper judgment of positions of embedded metals such as reinforcing bars, piping and the like, by displaying a grid scale corresponding to a scale plate which is constituted of grid-like divisions. CONSTITUTION:By applying a scale plate 7 which is constituted of gird-like divisions, to an object to be checked, such as a concrete structure, building and so on, and by making a magnetic sensor 1 scan on the scale plate 7, embedded metals such as reinforcing bars, pipings and so on, can be displayed on an image display 6 via the magnetic sensor 1, an electro-magnetic metal sensor 3 and an image processor 4. By combined effect derived from both of scanning position of the scale plate 7 and a TV image displayed on the image display 6, the positions of the embedded metals such as the reinforcing bars, pipings and so on, can be detected, found out and judged very quickly and appropriately.</p> |
