“…The grid area was considered to contain a defect, if the gradient and distance were larger than predefined thresholds; no guidance was provided for threshold selection. In an alternative approach, to identify cracks in asphalt paving, Tsai and Li [22] used a dynamic-optimization-based crack segmentation method followed by a linear-buffered Hausdorff scoring method for quantitative crack segmentation.…”

This paper presents the fundamental mathematics to determine the minimum crack width detectable with a terrestrial laser scanner in unit-based masonry. Orthogonal offset, interval scan angle, crack orientation, and crack depth are the main parameters. The theoretical work is benchmarked against laboratory tests using 4 samples with predesigned crack widths of 1-7mm scanned at orthogonal distances of 5.0-12.5m and at angles of 0˚-30˚. Results showed that absolute errors of crack width were mostly less than 1.37mm when the orthogonal distance varied 5.0-7.5m but significantly increased for greater distances. Orthogonal distance had a disproportionately negative effect compared to the scan angle.2

“…Although the error level of the automatic systems is acceptable compared to that of the human visual inspection [1], dealing with varying lighting conditions and low contrast images remains a challenge [2]. Therefore, precise knowledge of the road geometry emerges as a promising approach to improve automatic system performances.…”

In this paper, a comprehensive automatic visual inspection system for detecting pavement cracks, built around a Laser Road Inspection System (LRIS) onboard an instrumented vehicle, is presented. Two inertial profilers, a Differential Global Position System (DGPS), a high-definition camera and a high-speed area scan camera are the additional acquisition equipment. Visual appearance and geometrical information are obtained simultaneously since 3D profiles are obtained by capturing the laser line projected by the LRIS with the external area scan camera. Using AdaBoost algorithm for the combination of the processing results of these two types of data allows us to improve surface crack detection rates.

“…TLS produces high resolution, continuous transverse pavement profiles and it is insensitive to lighting conditions (day, night, or shadow) or low contrast conditions [126]. The high cost of the TLS instrumentation and hardware may make its implementation cost prohibitive.…”

Introduction Evaluating the condition of transportation infrastructure is an expensive, labor intensive, and time consuming process. Many traditional road evaluation methods utilize measurements taken in situ along with visual examinations and interpretations. The measurement of damage and deterioration is often qualitative and limited to point observations. Remote sensing techniques offer nondestructive methods for road condition assessment with large spatial coverage. These tools provide an opportunity for frequent, comprehensive, and quantitative surveys of transportation infrastructure. Methods The goal of this paper is to provide a bridge between traditional procedures for road evaluation and remote sensing methodologies by creating a comprehensive reference for geotechnical engineers and remote sensing experts alike. Results A comprehensive literature review and survey of current techniques and research methods is provided to facilitate this bridge. A special emphasis is given to the E. Schnebele ( ) · G.
