<p>PURPOSE:To image-display position and depth of embedded metals such as reinforcing bars, metal pipings and so on, with very simple handling, by analyzing and displaying detection signals by metal searching. CONSTITUTION:By moving a magnetic sensor 1, the sensor 1 detects reflected electromagnetic wave from embedded metals. From a metal searcher 3, detection information signal and coordinate signal of the embedded metals are transferred to an image processor 4 and the detection information is stored at a region b of a RAM 13 by a CPM 14. When the sensor 1 moves upto an end of horizontal line of a guide plate 7, the CPU 14 detects bringing-in of the detection information upto the end of one horizontal line and therewith displays a sample image displaying slant lines overlapping the horizontal line. The CPU 14 reads out the detection information in the region b and conducts analytical processing, and the analytical information is stored at the region c with the coordinate information. Then, the analytical information is read out and transferred to the display 4 as image data and therewith two dimensional analytical display image of the embedded metals is displayed.</p> |
