In close-range or unmanned aerial vehicle (UAV) photogrammetry, Schneider concentric
circular coded targets (SCTs), which are public, are widely used for image matching and as …

To address the issues of low tracking efficiency and poor localization accuracy of artificial
coded targets under complex background interference conditions, a new method for …

Conventional methods for measuring the deformational response of geosynthetics, such as
the linear variable differential transformers (LVDTs), strain gauges, and extensometers have …

To recreate high-quality three-dimensional (3D) models of rock joints for quantitative
roughness characterization more economically, portably, and quickly, it is necessary to …

Triaxial tests has been routinely used to measure the stress–strain relationship for
geomaterials. During triaxial testing, many sources of errors that cannot be completely …

Artificial point-distributed coded targets owns unique coded sequence numbers that can be
recognized automatically. To address the issue of decreasing recognition accuracy and …

A robust and effective method for the identification of point-distributed coded targets (IPCT)
in a video-simultaneous triangulation and resection system (V-STARS) was reported …

In close-range photogrammetry, circular-coded targets (CCTs) are a reliable method to solve
the issue of image correspondence. Currently, the identification methods for CCTs are very …

Circularly coded targets are widely used in 3D measurement, target tracking, augmented
reality, and other fields as feature points to be measured. The traditional coded target …
