Abstract
The article presents verification of robustness of contactless method based on 2D image camera, which is used to measure catenary contact wire position in changeable ambient lighting conditions. Robustness in changeable lighting conditions is ensured through the combination of advanced image processing for background information removal and the algorithm of error correction. This algorithm detects incorrect images and substitutes information from these images with proper measurement data obtained from correct images which precede and follow the incorrect one. The paper presents and discusses the processing algorithms used, as well as shows examples of measurement results obtained on a full scale laboratory stand.
