The two chunks have
been aligned based on the markers
with identical names, and merged.
The new chunk ‘merged chunks’
contains all images and all markers
(green circle). Note that the merged
sparse point cloud shows slight
alignment problems on the lower
left edge of the bone shaft near the
two markers ‘X 4’. However, the
near-perfect alignment of the
markers, so close that in the model
view they differ by less than three
pixels each, shows that each
individual set of images was wellaligned
(otherwise the 3D
placement of the makers would not
fit the other set).
