Absolute Position Determination with Single Vision Using Laser Range Finders

With the speed of information networks and the demand for real time service over the past few years, demand for up-to-date spatial information has accordingly been rising. Mobile mapping systems can be efficient equipments that meet such requirements to achieve real-time spatial information. For that, rapid absolute position determination is needed using images obtained from mobile mapping systems. A method has been proposed, which determine the absolute position of single vision in real time using sensor position, attitude information, and distances acquired from laser range finders. The proposed method provides the solution of absolute position with distances of more than 3 measuring points and angles between rays connecting the lens to the road surface. It is expected that the proposed method can perform rapid geospatial data generation from single vision by minimizing separate post-processing for absolute position determination.
