| Popis: | The aim of the study was to verify the possibility of registering video imagery acquired using a low-cost mobile platform mounted on a car. The platform consisted of an RTK GPS receiver, a laser rangefinder and a video camera. The first step of the algorithm is the video sequence acquisition by a video camera mounted on a car platform. The next stage relies on the automatic selection of video frames from video sequences based on the assumption that the overlap is 0.8. In order to determine linear exterior orientation elements, GPS RTK surveys had been used. In the bundle adjustment process, interior orientation elements had been taken into account. The calculated values of the video frames exterior orientation elements have been verified using coordinates from the geodetic network. |
