Digital Multispectral Images Superimposition Based on Preliminary Calibration or Contour Analysis: Advantages and Disadvantages

The article considers two approaches to solving the problem of multispectral images superimposition in vision systems: based on the search for key points correspondences and preliminary photogrammetric calibration using a universal test object. Shows two variants of the test object design. The advantages and disadvantages of superimposition of the visible and infrared images by two strategies are analyzed.
