Abstract: The research focused on the effects of camera heights and tilt angles on the ability to detect cracks in thermographs obtained with an infrared camera. Results indicate that differences in the accuracy of estimating percent area of cracks due to different camera tilt angles are significant. Differences among the errors due to different camera heights were not significant. Overall, temperature differences between pavement cracks and sound pavement may affect accuracy more than camera geometry.
