"Alignment" signifies the process of aligning the optical axes of two cameras. This can be effected in video real-time by means of image localization, as localization of a section of an image in a larger image is termed. An optimal localization procedure consists of filtering in order to decorrelate disturbing parts and of determining the error values or calculating a cross-correlation function. Suboptimal procedures are presented which yield feasible structures. Comparing the procedures shows that the highest localization frequency can be attained by combining standardized correlation with adaptive pre-processing. |
