| Abstract: | In the last decade, mobile mapping system has been one of the hot research spots in the field of survey and mapping, and also the typical represents of 3S integration technology. A mobile mapping system consists mainly of a moving platform, navigation sensors, and mapping sensors. The mobile platform may be a land vehicle, a vessel, or an aircraft. The navigation sensors mainly are Global Positioning System (GPS) receivers and Inertial Navigation System (INS). Objects to be surveyed are sensed directly by mapping sensors, for instance, Charge Coupled Devices (CCD), laser rangers, and radar sensors. Because the orientation parameters of the mapping sensors are estimated directly by the navigation sensors, complicated computations such as photogrammetric triangulation are greatly simplified or avoided. Spatial information of the objects can be extracted directly from the geo referenced mapping sensor data by integrating navigation sensor data. This paper presents the principle and method for the determination of the object oriented geometric parameters with imagery obtained by vehicle based CCD cameras. Some useful conclusions and suggestions are gained after the experiment. |
