Automated Macro Photogrammetry Station

Project Title: Automated Macro Photogrammetry Station

Description: Photogrammetry is the process of converting scores of photographs into three-dimensional models. The more photographs, the better the accuracy of the model: the operation usually involves taking hundreds of high-quality photographs from different angles. Photographs must have consistent focal lengths and focuses to generate an accurate model, and the limitations of taking photographs by hand often results in the loss of fine details. To combat this, the Digital Initiatives, Scholarship, and Collaboration (DISC) team built an automated macro-photogrammetry station from 3D printed, laser-cut, and purchased components. The station is based on the scAnt program and device, which was originally designed to photograph insects. A small object is placed inside a spherical enclosure illuminated with LEDs, eliminating messy backgrounds and variations in lighting. Rotating on a stand, the object is automatically photographed from different angles by a high-quality camera positioned on a slider. A program is used to adjust parameters such as camera and stepper settings. By increasing the speed and quality of the photogrammetry process, the scAnt device opens up a range of possibilities for digitally imaging and modeling anything from works of art to natural specimens to historical artifacts.
