A team in biology from the Universite de Montreal, the Montreal Botanical Garden, and McGill University has successfully used photogrammetry to quickly and accurately build a model of a flower from two-dimensional images and transform it into 3D. This is done in order to have greater clarity about the evolution of flowers. Photogrammetry is much more accessible, since it's cheap, requires little specialized equipment and can even be used directly in nature," said Marion Lemenager, a doctoral student in biological sciences at UdeM and lead author of the study. "In addition, photogrammetry has the advantage of reproducing the colours of flowers, which is not possible with methods using X-rays."
