Abstract
A system and method obtain first image data of a route at a location of interest from a first optical sensor disposed onboard a vehicle system moving along the route. The first image data depicts the route at the location of interest prior to passage of the vehicle system over the route at the location of interest. Second image data of the route at the location of interest is obtained from a second optical sensor disposed onboard the vehicle system. The second image data depicts the route at the location of interest after passage of the vehicle system over the route at the location of interest. A determination is made as to whether a change in the route has occurred at the location of interest by comparing the first image data with the second image data.
