That’s why I became interested in adapting technological tools to capture the form of flowers,” says McGill University professor Daniel Schoen, who first had the idea of applying photogrammetry to flowers, while doing research at the Institut de recherche en biologie végétale. “The variety of shapes and colours seen in the plant world are difficult to capture with simple photography. Databases of flowers – or even of complete plants – could give scientists and the public a way to finally see the unique features of plant species that remained hidden from view. Specimen from the collection of the Montreal Botanical Garden.Īccording to the researchers, photogrammetry has the potential to boost research on flower evolution and ecology by providing a simple way to access three-dimensional morphological data. Colours are then applied to the 3D flower using information from the photos.įlower of Schlumbergera sp. Thanks to the triangulation of common points present on the photos, it’s possible to reconstruct a 3D model of a flower. Photogrammetry uses information gathered from photos taken from different angles. The team, including researchers from McGill University, Université de Montréal, and the Montreal Botanical Garden, published the results of their work in the journal New Phytologist. This is the first time scientists have used the technique to study flowers. To better understand the evolution of flowers, researchers from Montreal are harnessing photogrammetry – a technique commonly used by geographers to reconstruct landscape topography.
