Fig. 2. — Argus Clicker can be used to quantify animal movement. Trajectories from two carpenter bees in the Argus tutorial videos. (A) Trajectories in an Argus Clicker screenshot (modified for visual clarity here) and the options panel. (B) Trajectories in 3D coordinates arrived at by reconstructing the 2D positions shown in A and 2D positions in the other two cameras (not shown). Reconstruction requires quantification of optical distortion and camera intrinsic parameters via Argus Patterns and quantification of camera extrinsic parameters via Argus Wand, after which Argus Clicker can be used to generate output similar to that shown above.
