Popis: Many applications developed for tracking moving objects apply multiple cameras distributed in the study scenario. However, this form requires a lot of effort to know the time position of the moving object to align the frames at the same time and position. This paper presents a study on the camera space-time alignment to increase the degree of certainty about the location of objects monitored by merging information obtained from cameras and GPS. The results obtained by testing on simulator and a study scenario showed a degree of 98% and 71.42% accuracy. The lower result in the actual scenario was due to GPS signal use limitation. The major contribution of this work is to provide an alternative to future works which propose solutions to the problem of spatiotemporal alignment of cameras without overlapping fields.
