Abstract

The problem of optimizing the disposition of a pair of video cameras to provide the maximum accuracy of the calculated radius and velocity vectors of natural and artificial objects in the atmosphere and near-earth space from double-station TV observations is considered. The effects of the video camera resolution and the accuracy of determining the positions of the observational sites on the accuracy of the calculated distance to the atmospheric object are investigated. A relation for calculating the relative determination error for the distance relative to the baseline is derived. Errors of components of the radius and velocity vectors are calculated using a Monte Carlo simulation of the direct problem. A 3D distribution is presented for the errors in calculating the coordinates of the object under observation. A demonstration is provided of the calculation accuracy for the absolute value of the body’s velocity and the error distribution for the velocity-vector direction on a sphere. The demonstration uses the calculated results for atmospheric kinematic parameters of meteors. A brief discussion is given of the possible fields to apply the results obtained: astronomy, geophysics, atmosphere physics, geodesy, aviation, and computer vision systems.

优化摄像机设置以最大程度地提高立体观测中自然和人造大气物体的坐标精度

摘要

考虑了优化一对摄像机的配置以提供从双站电视观测中计算出的大气和近地空间中自然和人造物体的半径和速度矢量的最大精度的问题。研究了摄像机分辨率和确定观测点位置的精度对所计算的距大气物体距离的精度的影响。得出用于计算相对于基线的距离的相对确定误差的关系。半径和速度矢量分量的误差是使用直接问题的蒙特卡罗模拟计算的。针对计算中观察对象的坐标中的误差,提供了3D分布。演示了物体速度绝对值的计算精度以及球面上速度矢量方向的误差分布。该演示将计算结果用于流星的大气运动学参数。简要讨论了应用所得结果的可能领域:天文学,地球物理学,大气物理学,大地测量学,航空和计算机视觉系统。
