METHOD FOR NON-CONTACT SOUNDING OF LEAKAGES, PARTICULARLY ON WATER AND SEWAGE PIPES

摘要

The aim of the invention is to achieve a sounding by means of computer-supported evaluation of technical, geographical, terrestrial and aero-terrestrial data, by application of aerial IR-sensor technology. Said aim is achieved as follows: Firstly, limiting conditions are determined and evaluated for an optimum application time. In addition to the above determination, DGPS, geographical and line parameters serve as the software input for a flight guidance and control system, for the aerial application of the sensor technology for the recording, automatic selection and transmission of said sensor values. The dynamic image data recorded as above is transmitted to an analytical unit, collated into an infra-red raster image, geo-referenced and equalised. For further evaluation, the images are processed by means of software as well as the above geographical and line parameters in such a way that so-called point accumulations can be identified as a collection of IR images and thus as anomalies. The anomalies are correlated with position co-ordinates for verification of damaged points.
