has been a low cost alternative [10], and is highly
accurate [11]. It also offers a quick, remote, three-dimensional (3D) data acquisition
with images that provide a permanent visual recording of the test. But the compulsory
use of targets might be disadvantageous in some circumstances; especially when the
access to the object is risky or even when it is inaccessible to operators. In contrast,
the depth dimension could be slightly solved, just avoiding the use of multiple convergent images. Due to the lack of scale definition in the photogrammetric process,
measurements must be taken by using additional instrumentation (for example, reflectorless
total station).
