In order to realize the dynamic imaging simulation for optical sensor in space rendezvous and docking, in this paper, a dynamic imaging modeling and simulation method for optical sensor is presented based on the general idea of surface meshcreating. The simulation models include geometry and optical characteristics models of space object and star background, imaging model of space based optical sensor, and the noise model during the process of imaging are given out. Taking advantage of these models, dynamic imaging simulation of optical sensor is finally accomplished. For two satellite objects, the imaging simulations are realized with this method in different conditions. Results show that the method could accurately and efficiently simulate the images of optical sensor, so this method could be applied in the development of space rendezvous and docking system.

“…The principle of stereophotogrammetric measurement has been well known for decades (Lane et al, 1993;Slama, 1980;Zhizhuo, 1996). The same object is seen from two different points of view and permits a three-dimensional stereoscopic observation.…”

This paper focuses on a topographic methodology to characterize the amount of sediment stored in channels and the use of historical photographs for aerial survey by stereophotogrammetry, as part of wider research on debris-flow magnitude prediction. The topographic methodology uses equidistant four-point cross-sections along the long profile of the channel. Each cross-section is representative of a 50-m reach of the channel. To calculate the volume of each reach, the difference is calculated between a reference level and the topographic surface. The reference level is the lowest level where the debris flow can erode, and in the current method this level is estimated from fixed points along the long profile of the channel. The accuracy of the method has been estimated by comparing results of a detailed topographic survey, with a standard deviation corresponding to about 6 per cent of the total calculated sediment volume.This topographic methodology has been used on aerial photographs by photogrammetry. This tool was applied to photographs taken on 12 past dates. The scales of the archive photographs used range from 1:3000 to 1:30 000, but results are consistent and permit us to calculate sediment states of the channel for different past dates with an uncertainty of about 6 per cent of the total volume. The application of the technique to the Manival debris-flow torrent has permitted us to propose some partial sediment budgets and erosion-rate estimates.

“…That is, based on the user-specified overlap, add the overlap correction relevant to the terrain undulation. If the influence of the terrain undulation to the photo overlap is not taken into account, the overlap may not be enough and there will be a "gap" [1,2] . However, the photo overlap must also not be too much, because it will reduce the efficiency of the aero photography and the succeeding steps.…”

In aerial photography, the primary factor is terrain undulation. However, most of the external aerial photography software used for aerial photography design do not take terrain undulation influence into consideration. Therefore, the design result has comparative randomicity and "gaps" are expected. An aerial photography design system is developed by analyzing the terrain undulation influence to the design result with DEM data so that the forward overlap and side overlap can be justified according to the block terrain undulation to meet specifications or standards. The data designed by this system is compared with the real flying data. The results show that making use of DEM to assist in aerial photography design can ensure that the designed result fits the real terrain better.
