Mathematical models and methods of objects spatial coordinates estimation in multiposition systems of thermovision in the infrared range of wave lengths and passive scanning systems of radiovision of millimetric range are considered. The aim of the work – is to develop methods of objects spatial coordinates estimation in the specified observation systems on the basis of matrix methods with determination of mutual orientation of observers coordinate systems allowing to increase the accuracy of estimates due to increase in number of observers. The methods based on observations classifications in case of search of conjugate couples of basis vectors of the directions on objects, measurement of range to them and determination of mutual orientation of coordinate systems for two observers by the results of classification are offered. The concept to create the system with more than two observers allowing to increase reliability of system and accuracy of coordinates estimates is formulated. Results of computer simulation in case of methods implementation are given. Influence of basis vectors determination errors on the accuracy of spatial coordinate estimates in case of unknown mutual observers orientation is considered.
Key words: multiposition systems, thermovision, passive radiovision, mutual orientation, the conjugate vectors, estimates of spatial coordinates, matrix methods.
