The problem of simulation modeling of formation and subsequent superposition of planar object images from multispectral cameras the homography matrix for which is estimated from the image of a universal planar test object is considered. The developed parametric model allows setting external and internal parameters of cameras, spatial coordinates of observation objects, measurement errors, forming frames from virtual cameras and performing their combination. As a result of simulation modeling, the authors have shown that in order to achieve the value of matching quality criterion based on the calculation of local area overlap area not worse than 0.8, permissible RMS errors of placement of test object reference emitters and estimation of their pixel coordinates should not exceed the values of 2.5 mm and 0.14 pixels, respectively.
Key words: : photogrammetry camera calibration, image imposition, homography matrix, test-object.
