It can also be flexibly adjusted according to requirement existing under locating actual conditions, herein and be not specifically limited.
Further, when perspective view and pictorial diagram are obtained respectively by two systems, it is more likely that because picture is differentiated
The different of rate setting causes perspective view and pictorial diagram to use different resolution ratio, this will lead to the size of two images not
One, it will interfered for fusion process, therefore in order to enable syncretizing effect more preferably, it is also necessary to when there are such situation, adjust
The resolution ratio of whole two images, so that two images are merged with identical size, so that in subsequent each pixel
Point is more accurate when being overlapped.
Specifically, the different two images of resolution ratio will necessarily have relatively large and relatively small, and resolution ratio
Adjustment be not that A figure is directly amplified to B figure or B figure is narrowed down into A figure because simple amplification and diminution are not influence point
Resolution, and the method that will lead to fogging image, therefore generally use field interpolation when increasing resolution ratio, reduce resolution ratio
Shi Ze is using local mean value or the method for equal interval sampling.And due to image it is big mean that data volume is big, brought to computer
Load is big, so more preferred mode is to adjust resolution ratio relatively large image using the mode for reducing resolution ratio
To another relatively small image of width resolution ratio, the load of computer is reduced with this.
