Abstract
In recent years, the necessity of efficient and high accuracy mapping method research is increasing. Aerial photogrammetry is one of the mainstream methods of mapping wide area. But the information, under elevated structures, in tunnels, shadow of buildings, and under street trees etc, cannot be captured from aerial photogrammetry. Therefore, the efficient data acquisition technique is required under those environments. This paper describes a data acquisition method using a Mobile Mapping System (MMS). MMS is a vehicle, which consists of GPS-Gyro/IMU combined navigation system and a CCD camera. In this paper, a road ortho mosaic creation algorithm is proposed and the result of road ortho mosaic image is introduced. And this paper describes advantage of road ortho mosaic over the aerial photogrammetry.
