Tips for Teachers: Paired-laser photogrammetry

This activity is based on a method used by field biologists called paired-laser photogrammetry. It’s used to remotely estimate the body size of free-ranging animals that would be difficult or impossible to measure directly. For simplicity, this activity ignores potential parallax or image distortion errors (discussed in references above).
