The topographic change has been estimated on basis of 3D laser data and aerial photogrammetric survey. The newly-developed, time-saving approach is by using airborne and ground-based lidar. A points-cloud of high precision and density distribution can be obtained in a few minutes for the sensitive latent landslide area. With a limited control survey of precise targets using GPS and total statio...

This paper presents the results of work carried out under the auspices of the joint ISPRS CNES Scientific Assessment Program of DEM generation from SPOT 5 high resolution stereoscopic (HRS) image data. A stereo pair of HRS images of Melbourne, Australia, with a ground sample distance of 5m in the along track direction, and 10m in the across track direction, was used to create digital surface mo...

this paper presents a control strategy for fuel cell/energy storage power generation system during voltage sag conditions. the hybrid dc power sources are connected to grid using power electronic converters include dc-dc converter and grid connected voltage source inverter. the power from hybrid power sources is controlled during voltage sag by designing of control strategy for dc-dc converter....

abstract this paper presents a multiobjective power control algorithm that updates the transmitted power based on local information. the proposed algorithm is expanded by using multiobjective optimization schemes. the objectives to be optimized in this paper are determined so as to reduce the sinr fluctuations as well as maintaining the sinr to an acceptable level with minimizing an average tra...

Relative to the rigorous physical model, rational polynomial coefficient (RPC) has been adopted as an alternative common sensor model data for image Geometric correction exploitation. In this paper, based on collected QuickBird imagery in Shanghai region, the iterative least-squares solution with regularization(ILSR) is derived to determine the RPCs by using 50 fair distributed ground control p...

This paper deals with the orientation of 3-line imagery which has been taken during the MOMS-02/D2 experiment in spring 1993, and which will be acquired in course of the MOMS-02/PRIRODA project, scheduled for launch in April 1996. The reconstruction of the image orientation is based on a combined adjustment of the complete image, ground control, orbit and attitude information. To this end, the ...
