Algorithm of definition of a situation and orientation of extended object on the basis of processing of pair the plotting received by spatially-carried template receivers

Statement of the problem. The quality of the functioning of the means of protection depends on the information support subsystem, in particular, on its algorithmic support, the improvement of which in terms of realizing the possibility of determining the spatial orientation and dimensions of an extended object will increase the effectiveness of protection methods.

Purpose. To develop algorithm of definition of a site and orientation of extended object on the basis of processing of pair the images received with use of spatially-carried matrix photodetectors and to define size of a realised error of measurement depending on parametres of optical system and a matrix photodetector.

Results. With attraction of methods of digital processing of images the algorithm allowing by allocation of characteristic points on images of projections of object and restoration of lines of position is developed to define its spatial orientation, a site, length and diameter. The results reflecting features of influence of parametres of optical system and a matrix photodetector on an error of measurement of spatial co-ordinates and overall dimensions of extended object are received.

Practical significance. The developed algorithm can be realised as a component of a subsystem of information support of the protection frames which efficacy depends on the had data about attacking object.
