Abstract

Optical route examination systems and methods described herein obtain image data of a field of view (108, 110) of a camera (106; 1606) disposed onboard a first vehicle (102; 1602) as the first vehicle (102; 1602) moves along a first route (120; 1620), and autonomously examine the image data onboard the first vehicle (102) to identify one or more of a feature of interest (200, 202, 204; 500; 804, 806, 808; 1000, 1002, 1004; 1100, 1102, 1104; 1704; 2002, 2006) or a designated object (200, 202, 204; 500; 804, 806, 808; 1000, 1002, 1004; 1100, 1102, 1104; 1704; 2002, 2006).
