Abstract
A system for range sensor-based calibration of roadside cameras includes one or more cameras and range sensors with overlapping fields of view of a roadway. Control logic stored within and executed by a controller includes control logic for capturing image and range sensor data, for filtering the data to focus on first and second regions of interest (ROIs); for filtering the data to focus on first and second movements of interest (MOIs); for filtering the data to focus on first and second objects of interest (OOIs); for filtering the data to focus on first and second positions of interest (POIs); and for defining that objects detected by the camera and sensor and that satisfy both the first and second ROI, MOI, OOI, and POI filters are matching objects. The control logic calibrates the camera by applying a correction factor based on the matching objects.
