Figure 4: Number of overlapping images computed for each pixel of the orthomosaic.
Red and yellow areas indicate low overlap for which poor results may be generated. Green areas indicate an overlap of over 5 images for every pixel. Good
quality results will be generated as long as the number of keypoint matches is also sufficient for these areas (see Figure 5 for keypoint matches).

The correlation between camera internal parameters
determined by the bundle adjustment. White indicates a full
correlation between the parameters, ie. any change in one can
be fully compensated by the other. Black indicates that the
parameter is completely independent, and is not affected by
other parameters.

T2
The number of Automatic Tie Points (ATPs) per pixel, averaged over all images of the camera model,
is color coded between black and white. White indicates that, on average, more than 16 ATPs have
been extracted at the pixel location. Black indicates that, on average, 0 ATPs have been extracted at
the pixel location. Click on the image to the see the average direction and magnitude of the reprojection error for each pixel. Note that the vectors are scaled for better visualization. The scale bar
indicates the magnitude of 1 pixel error.

Min Error and Max Error represent geolocation error intervals between -1.5 and 1.5 times the maximum accuracy of all the images. Columns X, Y, Z show the
percentage of images with geolocation errors within the predefined error intervals. The geolocation error is the difference between the initial and computed image
positions. Note that the image geolocation errors do not correspond to the accuracy of the observed 3D points.
