Abstract

Although advances in camera and sensing technology in the last decade helped propel the automation of pavement distress detection and characterization, increased equipment acquisition and running costs limit access to the most effective solutions. Furthermore, some of these advanced techniques require substantial human involvement to process and analyze data correctly. We propose a cost-effective, end-to-end automated approach to pavement condition assessment that employs a neural object detector to identify and measure instances of pavement distress in real time from oblique two-dimensional imagery acquired using an unmanned aerial vehicle. A state-of-the-art object detector architecture is applied to identify and localize pavement distress instances in these images. Camera data, information about Street View image acquisition conditions, and the principles of photogrammetry and planar homography are exploited to construct a mapping for translating pixel distances to real-world distances. This capability is integrated into the neural network inference process to derive an end-to-end system for real-time distress identification and measurement.
