Rapid imaging in the field followed by photogrammetry digitally captures the otherwise lost dimensions of plant specimens

PREMISE: We recognized the need for a customized imaging protocol for plant specimens at the time of collection for the purpose of three‐dimensional (3D) modeling, as well as the lack of a broadly applicable photogrammetry protocol that encompasses the heterogeneity of plant specimen geometries and the challenges introduced by processes such as wilting. METHODS AND RESULTS: We developed an equipment list and set of detailed protocols describing how to capture images of plant specimens in the field prior to their deformation (e.g., with pressing) and how to produce a 3D model from the image sets in Agisoft Metashape Professional. CONCLUSIONS: The equipment list and protocols represent a foundation on which additional improvements can be made for specimen geometries outside of the range of the six types considered, and an easy entry into photogrammetry for those who have not previously used it.
