<p>PURPOSE:To locate a fault point accurately by previously installing a high luminance lamp around an equipment and using the lamp as a reference point at the time of image processing. CONSTITUTION:An ITV camera 3 mounted at an angle overlooking transformation equipment and a high luminance lamp 1 set up onto a strut 2 within the angle of view of the ITV camera are installed to the micro-tower 4 of an electric power substation. A scanned image is displayed onto a CRT as shown in an image 7 through an image processor. The picture is stored in a memory while using the light source of the high luminance lamp as an image reference point 5. An image in (n) and an image in (n-1) are superposed while employing the light source of the high luminance lamp as the image reference point and the difference section is stored at that time. Likewise, images in (n-1) and (n-2) are also processed, and the difference section is added to the difference section of (n) and (n-1). Such processing is repeated up to images in (n-1) and (n-19), the sum of the difference sections obtained is superposed while using the reference point 5 of the image 7 as a reference, and the modality of an accident is displayed onto the display screen.</p> |
