摘要: Abstract A new method of analysing strain from initially random lines is presented, which simultaneously considers their deformed length and orientation. Each line modelled as a vector whose that the element relationship between dispersion these vectors established. The provides simple rapid estimate ratio for wide variety objects directly digitized shapes. may also remove some sampling bias in analysis discrete straight elements, but its main advantage it can be used to analyse curved outlines objects.
