Patchwork

Road-defect register · damaged area in m² measured with OpenCV 5
Synthetic survey over real roads. The roads, schools, hospitals and bus stops are real (OpenStreetMap). The dashcam video and the defects are simulated, so every measurement can be checked against exact ground truth. These are not real potholes.
