Nowadays, various registration systems, in which several general-purpose video cameras are used, are becoming increasingly widespread. They are used almost everywhere as in civilian areas: traffic monitoring, observation of large water areas and traffic flows, aerial photography, the creation of modern maps, etc., and in the military: reconnaissance, evaluation of the results of using various types of ammunition, etc. Since the video cameras used in such systems are not any specialized means of registration, but can be ordinary household and, moreover, of different types, the task of determining the discrepancy time in the operation of the video cameras of the registration system is relevant. To determine the time of mismatch of registration of two cameras, the method of registration in the field of view of each camera systems associated with the reference frequency generator is used. A test bench was developed to implement the proposed method. Approbation of the proposed method for determining the time of discrepancy between the registration of two cameras and the test bench developed for this purpose was carried out in the laboratory. It showed that the error in determining the time of mismatch did not exceed one millisecond. Thus, the proposed method and the developed test bench make it possible to quite accurately solve the problem of determining the discrepancy time of registration of two video cameras.
