Abstract:
This article deals with a Geographical Information System (GIS) module which complements a video-infrared integrated application system for pipeline leakage detection inspection. This system is based on the theory that under pressure, leakage can occur and part of the product goes from liquid to gas state. In the leaking vicinity (over the land surface or in the waters) the temperature will change allowing appreciate a thermal difference that can be registered by the video-infrared equipment resulting in thermal contrast over the land, so that the infrared (IR) equipment can be used successfully for detecting and determining pollution due to petroleum. Similar arguments follow for the gas case. The system is designed to receive data from various electronic devices which operate in different frequency ranges. Data validation must be carried with suitable formulas to get the best final yield. Three types of information sensors form the major part of equipment: an infrared camera, a vid
eo camera and global positional system (GPS). Equipment, software and some inspection results using this system are presented. Tests show that the flight conditions (120-140 km/h, altitude of 400-500 m) are suitable for inspection services.
