About This Seminar

The affordability and ubiquity of cameras have led to their increasing use in many disciplines. In plant phenomics, it is common to see experimental data based on image-derived measurements. This seminar will explain geometric camera calibration, whereby pixel measurements are mapped to physical measurements and the conditions under which participants can calibrate their own cameras. The value of using calibrated cameras in plant science experiments is the possibility of replacing scanners with cameras, using a variety of individual cameras in experiments, and ensuring integrity and consistency of image-derived measurements.

Participants will be able to (learning objectives):
