Computer vision supported pedestrian tracking: A demonstration on trail bridges in rural Rwanda
Fig 10
Daily total bridge crossings detected with computer vision algorithm, and daily CHIRPS remotely observed rainfall for four bridge crossings over about 2-14 weeks in fall 2019.
Non-zero rainfall is observed only for the Ruharazi and Kabere bridge sites, for which observations were available during the rainfall season September-November. Site-level and aggregated linear regressions (not shown) of daily bridge crossings compared to daily rainfall or 7-day mean rainfall did not indicate any correlation, indicating that bridge use during these observation periods at these sites was not dependent on rainfall.
